Foreword The Sicilian Defense The Sicilian Defense is an opening that commences with the moves 1.e4 c5. The Sicilian Defense is the most popular and best-scoring response to White’s first move 1.e4. For example, 1.d4, is a statistically more successful opening for White because of the high success rate of the Sicilian Defense against 1.e4. New In Chess stated in its 2000 Yearbook that of the games in its database, White scored 56.1% in 296,200 games beginning 1.d4, but 54.1% in 349,855 games beginning 1.e4, mainly because the Sicilian Defense held White to a 52.3% score in 145,996 games. 17% of all games between GMs and 25% of the games in the Chess Informant Database, begin with the Sicilian Defense Almost one quarter of all games use the Sicilian Defense. Grandmaster John Nunn attributes the Sicilian Defenses’ popularity to its combative nature since in many lines Black is playing not just for equality, but for the advantage. The drawback is that White often obtains an early initiative thus Black has to take care not to fall victim to a quick attack. Grandmaster Jonathan Rowson considered why the Sicilian Defense is the most successful response to 1.e4, even though 1...c5, develops no pieces and the pawn on c5 controls only d4 and b4. J.Rowson writes: ‘To my mind there is quite a straightforward explanation. In order to profit from the initiative granted by the first move, White has to make use of his opportunity to do something before Black has an equal number of opportunities of his own.’ However, to do this he has to make ‘contact’ with the black position. The first point of contact usually comes in the form of a pawn exchange which leads to the opening of the position. The thought behind 1...c5 is this: ‘OK, I’ll let you open the position, and develop your pieces aggressively, but at a price - you have to give me one of your center pawns.’ (Jonathan Rowson, Chess for Zebras: Thinking Differently About Black and White). By advancing the c-pawn two squares Black asserts control over the d4-square and begins the fight for the center of the board. The move resembles 1...e5, the next most common response to 1.e4, in that respect. Unlike 1...e5, 1...c5 breaks the symmetry of the position which strongly influences both players’ future actions. White, having pushed a kingside pawn, tends to hold the initiative on that side of the board. However, 1...c5 does little for Black’s development, unlike moves such as 1...e5, 1...g6, or 1...Nc6, which either develop a minor piece or prepare to do so. In many variations of the Sicilian Defense, Black makes a number of further pawn moves in the opening (for example, ...d6, ...e6, ...a6, and ...b5). Consequently, White often obtains a substantial lead in development and dangerous attacking chances. Meanwhile, advancing a queenside pawn has given Black a spatial advantage there and provides a 10

basis for future operations on that flank. Often, Black’s c5-pawn is traded for White’s d4-pawn in the early stages of the game granting Black a central pawn majority. The pawn trade also opens the c-file for Black who can place a rook or queen on that file to support the queenside counterplay.

History of the Opening The earliest recorded notes on the Sicilian Defense date back to the late 16th century by the Italian chess players Giulio Polerio and Gioachino Greco. As it was already mentioned above, the Sicilian Defense was analyzed by Giulio Polerio in his 1594 manuscript on chess, though he did not use the term Sicilian Defense. It was later the subject of analysis by leading players of the day Alessandro Salvio (1604), Don Pietro Carrera (c. 1617), and Gioachino Greco (1623), and later Conte Carlo Francesco Cozio (c. 1740). The great French player and theoretician André Danican Philidor opined of the Sicilian Defense in 1777, ‘This way of opening the game... is absolutely defensive, and very far from being the best... but it is a very good one to try the strength of an adversary with whose skill you are unacquainted.’ In 1813, the English master Jacob Henry Sarratt effectively standardized his English translation of the name of this opening as the Sicilian Defense, referring to an old Italian manuscript that used the phrase, ‘il gioco siciliano’ (The Sicilian Game). The Sicilian Defense was fairly popular for much of the nineteenth century as Louis-Charles Mahé de La Bourdonnais, Adolf Anderssen, Howard Staunton, Louis Paulsen, and Carl Jaenisch all played it with some consistency. In the ninth edition of Modern Chess Openings, Walter Korn noted that the Sicilian ‘received three of its earliest practical tests, and a big boost in popularity, in the 1834 MacDonnell [sic]-La Bourdonnais match, 1843 Staunton-St. Amant match, and the 1851 London Tournament’. Staunton wrote of the Sicilian Defense, ‘In the opinion of Jaenisch and the German Handbuch, with which I coincide, this is the best possible reply to 1.P-K4, (1.e4 in algebraic notation) ‘as it renders the formation of a center impracticable for White and prevents every attack.’ The opening fell out of favour in the later part of the 19th century when some of the world’s leading players rejected it. Paul Morphy, the world’s best player in the late 1850s, decried ‘that pernicious fondness for the Sicilian Defense... extending from about 1843 to some time after 1851.’ Wilhelm Steinitz, the first FIDE World Champion, also disliked the Sicilian Defense and rejected it in favour of 1...e5. The death of the opening’s two greatest proponents, Staunton in 1874 and Anderssen in 1879 also contributed to its decline. It has been said that ‘these losses almost dealt a knockout blow to the Sicilian because it took a long time to find such important figures to carry the Sicilian’s standard.’ George H. D. Gossip, in The Chess Player’s Manual, first published in 1874, wrote: ‘Of late years... 11

discoveries have been made which have the effect of considerably strengthening White’s attack, and the Sicilian Defense is now considered by most modern authorities to be a comparatively weak mode of play.’ Freeborough and Ranken, in their treatise Chess Openings: Ancient and Modern (1889, 1896), wrote that the Sicilian Defense ‘had at one time the reputation of being the best reply to 1.P-K4, but this has not been confirmed by popular practice. Several eminent players have, however, held to the opinion that it is quite trustworthy.’ The Sicilian Defense continued to be shunned by most leading players at the start of the 20th century, as 1...e5 held center stage. J.R.Capablanca, FIDE World Champion from 1921 to 1927, famously denounced it as an opening where ‘Black’s game is full of holes.’ Similarly, James Mason wrote: ‘Fairly tried and found wanting, the Sicilian has now scarcely any standing as a first-class defense... [It] is too defensive. There are too many holes created in the Pawn line. Command of the field, especially in the center, is too readily given over to the invading force.’ Siegbert Tarrasch wrote that 1...c5 ‘is certainly not strictly correct, for it does nothing toward development and merely attempts to render difficult the building up of a center by the first player... The Sicilian Defense is excellent for a strong player who is prepared to take risks to force a win against an inferior opponent. Against best play, however, it is bound to fail.’ The Sicilian Defense was not seen even once in the 75 games played at the great St. Petersburg 1914 tournament. However, some leading players such as Emanuel Lasker (FIDE World Champion from 1894 to 1921), Frank Marshall, Savielly Tartakower, Aaron Nimzowitsch, and later Max Euwe (FIDE World Champion from 1935 to 1937) played the Sicilian Defense. Even J.R.Capablanca and S. Tarrasch, despite their critical comments, occasionally played the opening. It was played six times (out of 110 games) at New York 1924. The following year, the authors of Modern Chess Openings (4th edition) wrote: ‘The Sicilian has claims to be considered as the best of the irregular defenses to 1.P-K4 at Black’s disposal, and has been practised with satisfactory results by the leading players of the day.’ In this period Black’s approach was usually slow and positional, and the all-out attacks by White that became common after World War II had not yet been developed. The fortunes of the Sicilian Defense were further revived in the 1940s and 1950s by players such as Isaac Boleslavsky, Alexander Kotov, and Miguel Najdorf. Reuben Fine, one of the world’s leading players during this time period, wrote of the Sicilian in 1948, ‘Black gives up control of the center, neglects his development, and often submits to horribly cramped positions. How can it be good? Yet, the brilliant wins by White are matched by equally brilliant wins by Black; time and again the Black structure has been able to take everything and come back for more.’ Later, Bent Larsen, Ljubomir Ljubojević, Lev Polugaevsky, Leonid Stein, Mark Taimanov and Mikhail Tal all made extensive contributions to the theory and practice of the defense. 12

Through the efforts of World Champions Bobby Fischer and Garry Kasparov, the Sicilian Defense became recognised as the defense that offered Black the most winning chances against 1.e4. Both these great players favoured sharp, aggressive play and employed the Sicilian Defense almost exclusively throughout their careers, burnishing the defense’s present reputation. Today, most leading GMs include the Sicilian Defense in their opening repertoire. In 1990, the authors of Modern Chess Openings (13th edition) noted that ‘in the twentieth century the Sicilian has become the most played and most analyzed opening at both the club and master levels.’ In 1965, in the 10th edition of that book, Grandmaster Larry Evans observed that: ‘The Sicilian is Black’s most dynamic, asymmetrical reply to 1.P-K4. It produces the psychological and tension factors which denote the best in modern play and gives notice of a fierce fight on the very first move.’

SD B33 - The Grivas Sicilian Introduction The Variation A number of systems in the labyrinth of the Sicilian Defense involve the idea of increasing central pressure by playing ...Qb6. The main object of this early queen move is to decentralise the strongly placed white knight on the d4 square. The most direct way to apply this idea is the ‘Grivas Sicilian’, which arises after the moves: 1.e4 c5 2.Nf3 Nc6 3.d4 cxd4 4.Nxd4 Qb6

In this way Black immediately achieves his goal of decentralization of the white knight but this comes at a price. It will cost a future tempo as the black queen is exposed and will have to retreat in order to free the b7-pawn to advance and to seek safety. On the other hand, when the black queen later retreats to c7, Black argues that the white knight was better placed on d4, so no damage has been done. In most of the games, sooner or later, White brings the knight back to d4 essentially giving Black an extra tempo! The work in front of you is the fruit of several years of both practical experience and theoretical research. I tried to describe the known lines of the variation, giving my assessments as clearly and 15

responsibly as possible, and generally to create a useful guide. I must clarify that I took the liberty of changing the move order of many games. In this way it was possible to form an acceptable guide, avoiding confusion with the multitude of transpositions (or mistakes) that have occurred. Of’ course, the way you reach a certain position is important, but most important is to examine how you want to proceed. True value comes from knowing what to keep and what to throw away.

Statistical Overview The system is classified under ECO (Encyclopaedia of Chess Openings) code B33. Various transpositions can arise and are classified under ECO codes B32, B42, B60, B64, B65 and B82. The readers using NicBase codes should locate the variation under the SI-34.1 key. A quick research on the ChessBase MegaBase reveals an interesting statistic: Black scores a good 55.3% based on approximately 8.550 games! Well, I do not know a lot of systems where White scores so poorly (44.7%) and this simply verifies the validity of the system! When comes to my official games, the score is even better for Black: 68.2% based on 143 games! Well, experience is quite helpful!

Why is it the ‘Grivas Sicilian’? I started playing this system regularly more than 35 years ago. During all these years I managed to play it in approximately 150 official games and numerous blitz and rapid games. At the same time, I was analyzing the variation and trying to systematize the various possibilities and transpositions. This means that I have already spent a good portion of my life with this variation! In my opinion, I became an expert in it and have offered a lot of new ideas and ways of handling the positions arising from this system. As the variation had no official name, GM John Nunn decided to baptize it with mine, as he thought that I am the Grandmaster who loves, believes, played and analyzed it more than any other in the world. I went even further, giving names to each of the sub-variations of the system. For this purpose, I used names from the ancient Greek Mythology, in a way explained in each chapter and this method, in my opinion, suits my purpose well. I hope that the reader will ‘excuse’ me for taking the liberty to assign nomenclature in the way described above and will understand and accept my point of view. It is not important who played a system first, and where. The most important is who made it wellknown and popular - Alexander Alekhine.

Why play the ‘Grivas Sicilian’ Many things in chess theory, as in life, are relative and a matter of taste. Actually, there are no ‘good’ 16

or ‘bad’ openings. There are openings that you know and understand, and openings that you do not know and do not understand. This variation offers a lot of possibilities, new ideas and practical benefits that cannot be underestimated in modern chess. Playing Black can either be fun or a disaster! My opinion is that a serious chess player should master strong weapons against any of White’s first moves and try to be a true specialist in these. He should choose lively variations that not only offer fair chances of winning, but also the possibility of learning new things from every game. Dull positions, where the maximum possible result would be a draw, are not my cup of tea. Playing the 4...Qb6 variation is an invitation to a real fight. The main object is to achieve the symbol oo, which means ‘unclear position’. Then it does not matter which color your pieces are. For a player with general knowledge of various Sicilian Defense schemes, it will be much easier to understand the main ideas and variations described in this work. In practice there are unlimited possibilities of transpositions, and an experienced adherent of this variation can make good use of them. The result will be of great value, as the opponent will be directed to less familiar ground where he may easily be outplayed. I do not claim that the ‘Grivas Sicilian’ is a super-strong weapon or that someone can score massively with the black pieces using it. But I do claim that by using this variation you will achieve perfectly playable positions in which, thanks to your deep knowledge, you can achieve your goals. I do not claim that everything written in this work is 100% safe and correct. As in every theory book, assessments can easily be changed in the future and at any time. But I do claim that I wrote the work in all honesty, and I presented everything I know. Of’ course, as I already mentioned, there will inevitably be a number of controversial assessments in a variation like this due to the many unclear positions it leads to. So, there is plenty of ‘food for thought’, double-checking and judgment. As complex theoretical systems never die, the reader can always discover new roads, new ideas and new moves. Above all, he can be creative.

History The history of the variation is partly unknown. The first official game where the system with 4...Qb6, was seen for the first time was back in 1881, in Berlin, between M.Chigorin and L.Paulsen. Of course, this game was a disaster for the variation, but we have to admit that Luis Paulsen was not familiar with the subtleties of the system and played it mostly as a surprise weapon. Michael Chigorin played excellently, and the variation did not pass the ‘exam’ Chigorin Mikhail Ivanovich Paulsen Louis B47 Berlin 1881 17

Later, GM Vladimir Akopian and GM Bojan Kurajica provided good examples of the vitality of the variation, playing it regularly and achieving excellent results with it. Even the best player of the world, GM Garry Kasparov, played it once, although this was a blitz game against the German GM Roland Schmaltz.

Breakdown of Chapters • Variation A (Medusa) deals with White’s entire 5th move deviations from the main continuation 5.Nb3. • Variation B (Eros) deals with White’s entire 6th move deviations from the main continuation 6.Nc3. • Variation C (Cyclops) deals with the Fianchetto system (7.g3). • Variation D (Poseidon) deals with all of White’s lines where the move Bg5 is played, starting with 7.Bg5. • Variation E (Hestia) deals with all of White’s lines where the move a3 is played, starting with 7.a3. • Variation F (Hera) deals with the very interesting setup involving 7.Qe2 and long castling. • Variation G (Fates) deals with a rare line starting with 7.Be2. • Variation H (Teiresias) deals with the Black’s 7th move deviations from the main move 7...d6. • Variation I (Hermes) deals with all of White’s lines involving the move a4, starting with 9.a4. • Variation J (Apollo) deals with all of White’s lines where the move Bd2 is played, starting with 11.Bd2. • Variation K (Dionysus) deals with the straightforward and sharp 8.f4. • Variation L (Athena) deals with the white queen’s placement on e2, commencing with 10.Qe2. In this line White can castle to either side, each option resulting in different types of middlegames. • Variation M (Zeus) deals with the white queen’s placement on f3, commencing with 10.Qf3. As in the previous chapter, also in this line White can castle to either side, resulting in different types of middlegame. This is actually the most popular variation of the system and the one that leads to the sharpest positions and the most unclear assessments. The reader should analyse it carefully and understand it in depth, in order to have a fair share of success. 21

Contributors - Helpers During all the years that I have played and analyzed the variation, there were certain people who offered me great help. These were: Nikolai Andrianov (Russia - m), Suat Atalik (Turkey - g), Kivanc Haznedaroglu (Turkey - g), Spyridon Skembris (Greece - g), Andrey Terekhov (Germany/Russia - f) and Antonios Vragoteris (Greece - f). Significant help for preparation of this work was provided by a team of people who checked, analyzed and offered me their ideas and their general opinions. These were: Nikolaos Gavrilakis (Greece - m), Spyridon Kapnisis (Greece - m), Sotirios Logothetis (Greece), Anastasios Michailidis (Greece), Ioannis Simeonidis (Greece - f), Andreas Tzermiadianos (Greece - m) and Robert Zysk (Germany - m). I would like to thank all these chess players for their trust and their valuable help.

www.ChessBomb.com This is the famous Grivas Sicilian with 4...Qb6, rightly named after the famous trainer Efstratios Grivas who deeply explored it in the early 90s. The main idea of this early queen move 4...Qb6 is to decentralise the strongly placed white knight on the d4-square. In this way Black immediately achieves his goal.

Lady Godiva My Big Love Many chess players fall in ‘love’ with certain openings. The reasons are unknown and it’s not really of any great value to deeply research it. After all life is all about choices and preferences... In my chess life I fell in love with a certain opening - a Sicilian branch - which is identified by the moves 1.e4 c5 2.Nf3 Nc6 3.d4 cxd4 4.Nxd4 Qb6

This affair even started at a very early stage of my chess life; just some months after I learned the moves of the game. And for the wrong reasons! I had just finished reading a survey on isolated pawns and as I was playing the Sicilian Defense, I became afraid that after the moves 1.e4 c5 2.Nf3 Nc6 3.d4 cxd4 4.Nxd4, White threats 5.Nxc6, either destroying my possibilities of castling after 5...dxc6 or leaving me with a weak isolated pawn on a7 after 5...bxc6. Yes, I was young and naive, but this is why I played 4...Qb6, so that I could recapture on c6 with my queen!! Maybe it is not so bad to be naive after all... So, here is my first ever game with my ‘love’, just for the record: Klebetsanis Kiriakos Grivas Efstratios B32 Athens 1979 23

1.e4 c5 2.Nf3 Nc6 3.d4 cxd4 4.Nxd4 Qb6 5.Be3 Qxb2 6.Nb3 Qe5 7.N1d2 Nf6 8.f4 Qc3 9.Kf2 Ng4+ 10.Qxg4 d5 11.Qd1 d4 12.Bxd4 Nxd4 1/2-1/2 A very bad game indeed, but please forgive me that I was not much more than a beginner - even GMs are at a certain point of their chess life! After some years I found this variation to be quite interesting and I inserted it in my openings arsenal. It served me well as I played it in approximately 150 official games (and numerous other games), scoring well over 70% which is an extremely good figure for the black pieces. I always called it the ‘Qb6 Sicilian’, until 2004, when I agreed to write an opening book about it. GM John Nunn thought that it deserved to be called the ‘Grivas Sicilian’ and from that time this name was adopted. Keep in mind that I was not the first to play it, but I am the one who loves, believes, played, and analyzed it more than any other in the world. I went even further, giving names to each of the sub-variations of the system. For this purpose, I used names from ancient Greek Mythology!

Lady Godiva Lady Godiva by John Collier, c. 1897 Herbert Art Gallery and Museum

Imagine my surprise when some years later I discovered that some sources were calling it the ‘Godiva’ variation. But what the heck is ‘Godiva’ I wondered. A quick search in Wikipedia revealed the following ‘truth’: Godiva (old English: Godgifu), known as Lady Godiva, was an 11th-century Anglo-Saxon noblewoman who, according to a legend dating back at least to the 13th century, rode naked through the streets of Coventry in order to gain a remission of the oppressive taxation imposed by her husband on his tenants. Lady Godiva was the wife of Leofric, Earl of Mercia. They had one proved son Aelfgar, Earl of Mercia. Lady Godiva’s name occurs in charters and the Domesday survey, though the spelling varies. The Old English name Godgifu or Godgyfu meant ‘gift of God’; Godiva was the Latinized version. The legend of the nude ride is first recorded in the 13th century, in the Flores Haustorium and the adaptation of it by Roger of Wendover; despite its considerable age, it is not regarded as plausible by modern historians, nor mentioned in the two centuries intervening between Godiva’s death and its first appearance, while her generous donations to the church receive various mentions. 24

According to the typical version of the story, Lady Godiva took pity on the people of Coventry, who were suffering grievously (maybe here we find a root for my surname - Grivas...) under her husband’s oppressive taxation. Lady Godiva appealed again and again to her husband, who obstinately refused to remit the tolls. At last, weary of her entreaties, he said he would grant her request if she would strip naked and ride through the streets of the town. Lady Godiva took him at his word and, after issuing a proclamation that all persons should stay indoors and shut their windows, she rode through the town, clothed only in her long hair. Just one person in the town, a tailor ever afterwards known as Peeping Tom, disobeyed her proclamation in one of the most famous instances of voyeurism. In the story, Tom bores a hole in his shutters so that he might see Godiva pass and is struck blind. In the end, Godiva’s husband keeps his word and abolishes the onerous taxes. The famous Godiva Chocolatier is named after Lady Godiva and features a stylized rendition of her ride as its logo. Now, compare the above diagram (the black queen and the black knight standing together in front of their army) with the painting (a noble woman and her knight out in the village streets). I really liked this story and I do not care if you call the variation either ‘Godiva’ or ‘Grivas Sicilian’, please do what makes you feel better! More to the point now! As I was an expert in this variation, I tried to teach it to my trainees. But very few of them took the risk of playing a rather razor-style opening where any result is possible and sometimes in a quick and cruel way. But of course, I never insist, as it is not nice for a trainer to try to force his own ‘loves’ on his trainees - keep that in mind - the Mysterious Mr. X would certainly disagree!

Sound or Not My general advice is not to ‘play’ the ‘Grivas Sicilian’! You need a lot of general and concrete knowledge; you need to be a mature player before all. I have noticed that it is easier to play it with White as the moves and plans (attack!) are easier to find and to play. The variation is sound and offers rich possibilities allowing Black to play for a win as well.

Chapter 1 - Move By Move Variation A - Medusa B32-B33 The next diagram ‘identifies’ the turning point of the Medusa variations which after 1.e4 c5 2.Nf3 Nc6 3.d4 cxd4 4.Nxd4 Qb6

includes everything else than the ‘usual’ 5.Nb3. Although 5.Nb3, has always been the main continuation, some alternatives come into consideration. These alternatives seem mostly innocent, but they require sufficient knowledge from Black to avoid been tricked. These lines are mostly played to avoid home preparation, but even though they are successful from time to time, in the long run they have to be discarded in favour of more dangerous lines. I have to admit that the A8 line is the most interesting of all, although it doesn’t seem to promise White any advantage. But before we go on, let’s see why I named the variation after the ugliest creature of ancient Olympus’ Mountain. Nomenclature Medusa under the Microscope Medusa was an ugly creature, daughter of Phorkys and Keto, the children of Gaia (Earth) and Okeanos (Ocean). She was one of the three sisters known as the Gorgons. The other two sisters were Sthenno and Euryale. Medusa was the only mortal of the three and used to be very beautiful. She lived far up north, where the sun didn’t shine. 26

Being very curious, she wanted to see the sun, and thus asked the Goddess Athena for permission to visit the south. Athena refused, but then Medusa got angry and dared to claim that Athena hadn’t given her permission because she was jealous of her beauty. Athena was angered and punished her by turning her hair into snakes and placed a curse on her, making her so ugly that whoever looked into her eyes would turn into stone. Medusa was a dangerous creature but if you knew how to handle her she was harmless. Now let us look at the above diagram and review White’s alternatives to 5.Nb3.

Variation A1 - Medusa - 5.? 1.e4 c5 2.Nf3 Nc6 3.d4 cxd4 4.Nxd4 Qb6

5.Nc3? Of course we have come across the same blunder by the ‘alternative’ 5.Bd3? Nxd4 (5...Qxd4 0–1 Joksimovic,L-Kocovski,I Boskovic 2004) 6.Be3 Qxb2 7.Nd2 Nc6 8.Nc4 Qc3+ 9.Bd2 Qf6–+ Henriques,S-Almeida,J Benedita 1998. 5...Qxd4 5...Nxd4, will also do the job: 6.Be3 e5 (6...Nxc2+? 7.Qxc2± De la Pena Lleranti,A-Rey Farina,A Ferrol 2002) 7.Nd5 Qa5+ 8.c3 Ne6–+. 6.Bd3 6.Qxd4 Nxd4 7.Bd3 a6 8.Nd5 Ne6–+ Dimitrov,V-Veselinov,S Sofia 2007. 27

6...Qb6 Or 6...e6 7.Be3 Qb4 8.0-0 a6 9.a3 Qa5 10.Kh1 Nf6 11.f4 d6 12.b4 Qc7–+ Hoegy,K-Iwanziw,N Heusenstamm 2009. 7.0-0 7.Nd5 Qd8 8.Bf4 d6 9.0-0 e6 10.Ne3 Nf6 11.Bg5 Be7–+ Kamara,A-Kigigha,B Monrovia 2017. 7...e6 8.a3 a6 9.Rb1 Nf6 10.Be3 Qc7 11.f4 d6

And Black wins as in Biszof,H-Pazdziora,M Rewal 2006.

Variation A2 - Medusa - 5.Ne2 1.e4 c5 2.Nf3 Nc6 3.d4 cxd4 4.Nxd4 Qb6 5.Ne2

28

A very passive move, allowing Black to obtain an excellent position without much trouble. 5...Nf6 5...e6, is possible as well: 6.Nbc3 Nf6 7.h3 Bb4 (7...d5 8.Be3 Bc5³) 8.Be3 Bxc3+ 9.bxc3 (9.Nxc3 Qxb2 10.Nb5 (10.Bd2 0-0 11.Bd3 d5³) 10...Nxe4µ) 9...Qa5³ Sanchez Antunez,A-Pedraza Fernandez,M Malaga 2012. 6.Ng3 After 6.Nbc3? Ng4! White faces problems! 6...e6 Interesting is the active 6...h5!?, but it remains untested. 7.Be2 d5

29

And Black has already the slightly better prospects, as in Fehr,R-Ilic,Z Bern 1990.

Variation A3 - Medusa - 5.Nf5 1.e4 c5 2.Nf3 Nc6 3.d4 cxd4 4.Nxd4 Qb6 5.Nf5

This does not seem like a ‘natural’ move and I could even call it a mistake. Anyway, Black should react actively. 5...d5

30

The alternatives: 5...Nf6 6.Nc3 d6 (6...Nxe4!? 7.Nxe4 Qa5+ 8.Bd2 Qxf5 9.Bd3 Qe5 10.0-0 d5° Butti,E-Bassan,R Buenos Aires 2009) 7.Bd3 g6 8.Ne3 Bg7 9.0-0 0-0= Preuschoff,M-Rosen,W Germany 2005, and 5...a6 6.Be3

6...Qd8? (6...Qxb2 7.Nd2 Qc3µ) 7.Nd4? (7.Nc3 Nf6 8.Bc4±) 7...Nf6 8.Nc3 e5 9.Nf5 d5 10.exd5 Nb4= Shabalov,A-Yermolinsky,A North Bay 1994 are not bad for Black either, while 5...e6 6.Nd6+ Bxd6 7.Qxd6 Nf6 8.Bd3 Qb4+, is just equal. 6.exd5 Not of course 6.Be3? Qxb2–+, but possible is 6.Qxd5 Nf6 7.Qd3 Nxe4 (7...Bxf5!? 8.exf5 Rd8 9.Qb5 Qc7°) 8.Qxe4 Qa5+ 9.Bd2 Qxf5=. 6...Bxf5 7.dxc6 Qxc6 8.Nc3 a6

31

And Black has achieved an excellent Sicilian Defense middlegame.

Variation A4 - Medusa - 5.Be3 1.e4 c5 2.Nf3 Nc6 3.d4 cxd4 4.Nxd4 Qb6 5.Be3

An aggressive but not fully correct idea. By sacrificing the b pawn, White tries to grab the initiative. Compared to similar Sicilian lines, this one is not an easy case for White. 5...Qxb2

32

It seems that Black can also go for 5...Nf6? 6.Nc3 a) 6...Ng4?! 7.Nd5! (7.Qxg4? Qxb2 8.Nb3 Qxc3+ 9.Bd2 Qxc2µ) 7...Nxe3 (7...Qa5+ 8.Bd2 Qd8 9.Nb5 1–0 Neelakantan,N-Nagendra,R India 1988) 8.fxe3! (8.Nxb6? Nxd1 9.Nxa8 Nxb2 10.Nc7+ Kd8 11.Ncb5

This is the main alternative to 5.Nb3. It has recently enjoyed a respectable theoretical status and many players playing with the white pieces have included it in their repertoire.

With equal chances, in an opposite-coloured ending. Conclusion Over the past few years many games were played following the footsteps of the Medusa variations. This happened because many (sitting behind the white pieces) low-rated players are unwilling to enter the labyrinths of the main lines (no wonder why they are low-rated...), going for less analyzed but rather harmless continuations. The main conclusion is that Black faces nearly no problems, but he should always do his homework! Also, the A8 variation looks like a serious one and cannot be underestimated.

Variation B - Eros B32 The starting point of the next diagram ‘identifies’ the turning point of the Eros variations which after 1.e4 c5 2.Nf3 Nc6 3.d4 cxd4 4.Nxd4 Qb6 5.Nb3 Nf6

Includes everything but 6.Nc3. Although 6.Nc3, has always been the main continuation, some alternatives come into consideration and need to be examined. These alternatives seem mostly innocent, but they require sufficient knowledge from Black to avoid been tricked. These lines are mostly played to avoid home preparation, but even though they are successful from time to time, in the long run they have to be discarded in favour of more challenging lines. But before we go on, let’s see why I named the variation after one of the most loved semi-Gods of ancient Olympus’ Mountain. Nomenclature Eros under the Microscope Eros was the son of Aphrodite. He was the God of Love and in particular, erotic romantic love. He was often represented blindfolded because love is often blind! His ‘weapon’ was his bow and arrows (or darts). In either case the tips had been magically treated to induce either uncontrollable love or insurmountable disinterest in the first person seen by Eros’s victim after the wound. Chess players tend to ‘fall in love’ with less known theoretical branches, in order to avoid being out 123

prepared. This is often a ‘blind’ and mostly a wrong attitude. But let us see each of the sub-lines mentioned above in detail.

Variation B1 - Eros - 6.f3 1.e4 c5 2.Nf3 Nc6 3.d4 cxd4 4.Nxd4 Qb6 5.Nb3 Nf6 6.f3

The text loses precious time and seriously weakens the g1-a7 diagonal, but White hopes that it will be possible to construct a ‘Hedgehog’ formation, strengthening the center. The move cannot be recommended. 6...e6 Instead, Black has tried the following alternatives: a) 6...a5 a1) 7.c3 e6 8.N1d2 d5 9.exd5

With an equal game. Conclusion During the last years many games were played following the footsteps of the Eros variations. This happened because many (sitting behind the white pieces) low-rated players are unwilling to enter the labyrinths of the main lines, exactly as in the previous sub-chapter, going for less analyzed but rather harmless continuations. The main conclusion is that Black faces nearly no problems, but he should have done his homework, especially in the b3 line.

Variation C - Cyclopes B45 The Cyclopes variation arises after the moves 1.e4 c5 2.Nf3 Nc6 3.d4 cxd4 4.Nxd4 Qb6 5.Nb3 Nf6 6.Nc3 e6 7.g3

But before we go on, let’s see why I named the variation after the famous giant-fighters of ancient Greek mythology. Nomenclature Cyclopes under the Microscope The Cyclopes were gigantic one-eyed monsters. The most famous of them was Polyphemus, the Cyclopes blinded by Odysseus (Ulysses). Hesiod mentions only three, Arges (thunderbolt), Steropes (lightning), and Brontes (thunder), obviously storm semi-Gods. They were born to Gaea (earth) and Uranus (sky) and they were also the first smiths. When Cronus came to power he imprisoned the Cyclopes in Tartarus, but they were released by Zeus and fought with him against the Titans. As a reward for their release the Cyclopes gave Zeus their weapons of lighting and thunder. They continued as his workers at Mount Olympus, forging his thunderbolts. Arges was killed by Hermes while he guarded Io for Hera, and Apollo killed at least one of the Cyclopes as retribution for Zeus killing his son Aesculapius. The development of the f1-bishop to g2 (fianchetto) reminds one of ‘one eye looking at the center’. The fianchetto variation is quite playable, though not very ambitious. But it must be noted that a lot of transposing lines are on the cards. 174

Many games have started with a different move order: 1.e4 c5 2.Nf3 e6 3.d4 cxd4 4.Nxd4 Nf6 5.Nc3 Nc6 6.g3 Qb6 7.Nb3, which is classified under the B45 ECO code. Returning to our subject we must point out that White’s main idea is (as said) to develop his f1bishop on the long diagonal, controlling the center and especially the d5-square. His light-squared bishop will not be anymore ‘exposed’ on d3, but it will apply pressure down the h1-a8 diagonal (if this can be achieved). In many lines White gets doubled c-pawns and in general a weak queenside pawn structure. But on the other hand, he can use the bishop-pair and pressure along the b-file. His compensation, although not a long-term one, cannot be underestimated. Black could easily face serious problems if he is not well prepared for this somehow ‘unpleasant’ continuation.

Variation C1 - Cyclopes - 7...Bb4 1.e4 c5 2.Nf3 Nc6 3.d4 cxd4 4.Nxd4 Qb6 5.Nb3 Nf6 6.Nc3 e6 7.g3 Bb4

Black’s most principled move, trying to achieve ...d5 as quickly as possible. Of course, Black can try some standard setups with (keep in mind that there exist various transpositions): a) 7...Be7 (in general the text is not advisable as White is now a tempo up in a classical ‘Sicilian Scheveningen’ set-up) 8.Bg2 0-0 9.0-0 d6 10.Be3 Qc7 11.f4 a6 12.a4 b6 13.g4!

With equal chances. Conclusion The fianchetto line is quite interesting and Black should have done his homework in order to equalize and then seek his fair share of success. There are not many important games played lately which could change the evaluation of the variation, but the evaluation of certain positions has changed! And now we can be assured that Black is not facing particular problems if he has done his homework!

Variation D - Poseidon B33 The Poseidon variation arises after the moves 1.e4 c5 2.Nf3 Nc6 3.d4 cxd4 4.Nxd4 Qb6 5.Nb3 Nf6 6.Nc3 e6 7.Bg5

But before we go on, let’s see why I named the variation after one of the Olympus Mountain ancient Gods. Nomenclature Poseidon under the Microscope God of the sea, protector of all waters, Poseidon was the brother of Zeus. After the overthrow of their Father Cronus, he drew lots with Zeus and Hades, his other brother, to split the world. His luck was to become lord of the sea. He was widely worshipped by seamen and married Amphitrite, granddaughter of the Titan Oceanus. At one point he desired Demeter. To put him off, Demeter asked him to create the most beautiful animal that the world had ever seen. So, in order to impress her, Poseidon created the first horse. In some accounts his first attempts were unsuccessful, and he created a variety of other animals in the process. By the time the horse was created, his passion for Demeter had cooled off. His weapon was the trident, which can shake the earth and shatter any object. He was second only to Zeus in power amongst the Gods, but he had a difficult and quarrelsome personality. He was greedy and had a series of disputes with other gods when he tried to take over their cities. The development of the white bishop to g5 reminds one of a trident, spearing the black knight on f6. 210

So, returning to our subject, we must point out that Bg5 is a frequent move in all Sicilian schemes. White wants to ‘pin’ the f6-knight, increasing the force of a future e5 advance. On the other hand, Black has many resources, starting from this early point. We will examine each of these moves separately:

Black should be satisfied with the outcome.

This looks a little bit more passive than 7...Bb4, but transpositions can force this. An interesting alternative is 7...a6 8.Qf3 (8.Qd2 Qc7 Dominguez P.,L-Polgar,J Khanty-Mansiysk 2011 - see the analyzed game in the Middlegame Strategy chapter) 8...Be7 9.Qg3 d6 10.0-0-0 (grabbing a pawn with 10.Bxf6 Bxf6 11.Qxd6 Bxc3+ 12.bxc3 Qd8, is what would make Black happy

For more info now, see the analyzed game Dominguez Perez,L-Polgar,J Khanty-Mansiysk 2011, in the Middlegame Strategy chapter. Now White can choose in-between 8.Be2, 8.Qd2 and 8.Bd3. R Variation D21 - Poseidon - 8.Be2 1.e4 c5 2.Nf3 Nc6 3.d4 cxd4 4.Nxd4 Qb6 5.Nb3 Nf6 6.Nc3 e6 7.Bg5 Be7 8.Be2

219

This looks like a passive set-up, but it is mainly transposing to lines of the Apollo variation. 8...a6 I must mention that usually the variation currently under examination arises by transposition which explains its significance. Now Black can play the strong 8...Ng4!

9.Bxg4 Bxg5³. Another unadvisable option is 8...h6?! 9.Be3 Qc7 10.f4 d6 11.0-0 a6 12.a4 Bouaziz,S-Csom,I Nice 1974. Black’s extra move ...h6 is not positive at all, as it weakens the kingside. 9.0-0

220

9.Qd2 does not frighten Black: 9...Qc7 10.h4 b5 11.a3= Pavit,S-Luu Quang Dao Vung Tau 2008. 9...d6 Black should refrain from 9...Qc7 10.f4 h6 11.Bxf6 gxf6 12.Bh5² Maki,V-Silva Sanchez,C La Valetta 1980, but fully playable is 9...0-0 10.Kh1 Qc7 11.f4 d6 12.Bf3 Rb8 13.Qd2 b5∞ Kruml,DManik,M Litomysl 1994. 10.a4 Qc7 11.a5

248

And Black’s chances are by no way worse. Conclusion The Poseidon variation is quite a valid Sicilian system for White. Black has enough resources to preserve the balance, having his fair share of success. Black had always found ways for counterplay and finally I think that he faces no real problems. As the reader can point out, not much new stuff was played during the last years with the Poseidon variation - it seems that the White players do not follow it.

249

Variation E - Hestia B33 The Hestia variation is identified after the placement of White’s rook pawn on a3, at any moment, but usually after 1.e4 c5 2.Nf3 Nc6 3.d4 cxd4 4.Nxd4 Qb6 5.Nb3 Nf6 6.Nc3 e6 7.a3

But before we go on, let’s see why I named the variation after one of the Goddess of the ancient Greek Mythology. Nomenclature Hestia under the Microscope Hestia was Zeus’ sister. She was a virgin Goddess and didn’t have a distinctive personality. She played no particular part in the myths. She was the Goddess of the Hearth; the symbol of the house around which a newborn child was carried before it was received into the family. Each city had a public hearth dedicated to Hestia, where the fire was never allowed to go out. Of all the Olympians she was the mildest, most upright and most charitable. With the move 7.a3, White tries to secure his ‘house’, avoiding any possible dangers with ...Bb4 or with ...b5-b4 chasing the strong c3-knight away.

Variation E1 - Hestia - 8.? 1.e4 c5 2.Nf3 Nc6 3.d4 cxd4 4.Nxd4 Qb6 5.Nb3 Nf6 6.Nc3 e6 7.a3

250

White’s idea is to prevent a possible ...Bb4, or ...Nb4. If White wants to play a3 it is better to do so on the 7th move before Be3 is played. The point is that then, if Black doesn’t play precisely, White can achieve an advantage with Bf4. On the other hand, there are negative sides: White cannot castle long anymore and Black can create quick counterplay with ...b5-b4, opening up the queenside. 7...Qc7! One of the very few lines where Black ‘should’ retreat his queen early! Other continuations seem to favour White, although things are far from easy: a) 7...d6?!

Black’s chances seem to be at least equal.

The placement of the dark-squared bishop on d2 and not on the e-file, will help White to achieve the e5 advance under more favorable circumstances. 11...0-0 324

Black can also delay castling by 11...b5 12.Qf3 Bb7 13.Rae1 b4 14.Nd1 (14.Ne2 bxa3 15.bxa3 d5 16.exd5 Nxd5 17.Qh3 Nf6∞ Jusic,Z-Sandhoefner,F Austria 2015; 14.axb4 Nxb4 15.Nb5 axb5 16.Bxb4 0-0 17.Kh1 Ra2∞ Maenhout,T-Motwani,P Aalst 2005) 14...bxa3 15.bxa3 a5 16.a4 0-0 17.Nc3 Nb4 18.Nb5 Qd7∞ Satyapragyan,S-Sherbakov,R Raipur 2002. 12.Kh1 This is the most popular move, protecting the king from nasty checks down the g1-a7 diagonal.

White’s positions have been improved in recent years but probably cannot give more than equality. Further, a large number of games have been played with the Hestia variation, but without big success for White...

346

Variation F - Hera B33 The Hera variation arises after the moves 1.e4 c5 2.Nf3 Nc6 3.d4 cxd4 4.Nxd4 Qb6 5.Nb3 Nf6 6.Nc3 e6 7.Qe2

But before we go on let’s see why I named the variation after this Goddess of Mount Olympus. Nomenclature Hera under the Microscope Hera was Zeus’ wife and sister. She was raised by the Titans Ocean and Tethys. Hera was the supreme Goddess, Goddess of marriage and childbirth, and took special care of married women. Hera’s marriage with Zeus was founded in strife and continued accordingly. Zeus courted her unsuccessfully. He then turned to trickery, changing himself into a dishevelled cuckoo. Hera felt sorry for the bird and held it to her breast to warm it. Zeus then resumed his normal form and taking advantage of the surprise he gained, raped her. She then married him to cover her shame. Her sacred animals were the cow and the peacock, and her favorite city was Argos. The early 7.Qe2, fits perfectly with the intentions of Hera, those of ruling the game. Returning to our subject we must point out that White’s main idea is to quickly castle long and then effectively advance his kingside pawns. His light-squared bishop will not be anymore ‘exposed’ on d3, but it will apply pressure down the h1-a8 diagonal (if this can be achieved). Black could easily face serious problems if he is not well prepared for this somehow ‘unpleasant’ continuation. 347

But I must note that lately the Hera variation became a fashionable project for players with White and many games have been played and many players as well have stated that this particular variation can be the refutation of the ‘Grivas Sicilian’. This opinion is supported by some false analysis and wrong evaluations or suggested variations that have been spread around the internet. Well, that’s good news for players with the black pieces!

Variation F1 - Hera - 9...? 1.e4 c5 2.Nf3 Nc6 3.d4 cxd4 4.Nxd4 Qb6 5.Nb3 Nf6 6.Nc3 e6 7.Qe2

7...Bb4 The main line and in my opinion best. Alternatives lead to a more complex game and the types of positions that arise resemble the ‘Keres Attack’ schemes, but in a more favorable form for White. Perhaps Black’s play may be improved in several variations, White could claim a more pleasant position in the following examples. Keep in mind that there do exist various transpositions: a) 7...d6

This is mostly used in order to avoid a long theoretical battle, but it is also a perfectly playable option. Black eliminates the basic controller of the d5-square, planning to continue with ...e5 and then ...d5. The b3-knight is a bit out of play thus helping Black to acheive his mission. Although not attractive at first look, it can be quite dangerous. 10.Bxc3 e5 11.0-0-0 The alternative is 11.Rd1?! Re8!

Kanep,M-Seeman,T Rakvere 2009. An unclear position, where Black seems to be fairly active. Conclusion A fashionable variation where White has tried to create new ways to handle the opening. 428

Nevertheless, Black has several resources and a well prepared player can come out on top in no time. In general, we can see many new and interesting games played the last years with the Hera Variation. White has tried to be creative, but Black has always found counterplay and finally I think that he faces no real problem.

Variation G - Fates B33 The starting point of the next diagram ‘identifies’ the turning point of the Fates variation, which comes after 1.e4 c5 2.Nf3 Nc6 3.d4 cxd4 4.Nxd4 Qb6 5.Nb3 Nf6 6.Nc3 e6 7.Be2

In any case this is a line that should not be adopted by White so quickly as it allows Black an easy game after the obvious 7...Bb4. But before we go on, let’s see why I named the variation after some of the most feared creatures of ancient Greek Mythology. Nomenclature Fates under the Microscope The Fates had the subtle but awesome power of deciding a man’s destiny. They assigned a man to good or evil. Their most obvious task was determining how long a man lives. There were three Fates: Clotho the spinner, who spanned the thread of life; Lachesis the measurer, who chose the lot one had in life and determined how long it would be and Atropos the inevitable, who with her shears would cut the thread of life resulting in death. The Fates were old and predated the Gods. It is not entirely clear how far their power extended. It is possible that they determined the fate of the Gods as well. In any case, not even the most powerful beings in earth (or above it!) were willing to trifle with them. With the 7.Be2 White is challenging his fate as Black can choose between transposing into lines of the Be2/Be3 system with 7...d6 (not advisable), or simply accepting the challenge with 7...Bb4. 430

Now we will examine each of the above lines in detail.

Variation G1 - Fates - 8.? 1.e4 c5 2.Nf3 Nc6 3.d4 cxd4 4.Nxd4 Qb6 5.Nb3 Nf6 6.Nc3 e6 7.Be2

It must be mentioned that it is imprecise for White to play the text so early, before Black has committed himself to the development of his dark-squared bishop. The reason for this is the possibility of the...Bb4 pin which has been proved effective in practice. 7...Bb4 The natural follow up. 7...d6 8.Be3 Qc7 9.f4 a6, could be another try by Black, but it is not as attractive as the text! 8.0-0

431

Variation H - Teiresias B33 The starting point of the next diagram ‘identifies’ the turning point of the Teiresias variation which comes after 1.e4 c5 2.Nf3 Nc6 3.d4 cxd4 4.Nxd4 Qb6 5.Nb3 Nf6 6.Nc3 e6 7.Bd3 and it is indicated when Black doesn’t go for 7...d6:

But before we go on, let’s see why I named the variation after one of the most ‘respected’ figures of the ancient Greek Mythology: Nomenclature Teiresias under the Microscope Teiresias was a famous prophet from the town of Thebes. He accidentally came across Athena while she was bathing so she blinded him. After his mother pleaded, Athena gave Teiresias the gift of prophecy to compensate for his blindness. Among his prophecies were a warning to Pentheus to recognize and honor Dionysus when he first appeared in Thebes and a prediction of the greatness of Hercules. He revealed to Oedipus that he had unknowingly murdered his own father and finally he advised Odysseus on how to placate Poseidon. Black could easily get ‘blinded’ by the ‘beauty’ of side-lines. But he should not deviate from the main lines as the prophecy will prove annoying for him. But let us examine each of these the ‘sub-lines’.

Variation H1 - Teiresias - 7...? 453

1.e4 c5 2.Nf3 Nc6 3.d4 cxd4 4.Nxd4 Qb6 5.Nb3 Nf6 6.Nc3 e6 7.Bd3

In my opinion the proper handling of the variation lays in the move 7...d6 Nearly all roads lead to Rome (the basic position with ...d6, ...a6 and ...Be7), but Black should be careful not to mishandle the position. Thus, as 7...d5?! 8.exd5 (8.Be3 Qd8 9.exd5 Nxd5 10.Nxd5 exd5 11.Qh5 Be6 12.Nd4 Nxd4 13.Bxd4± Nemeth,G-Haselbach,D Hungary 2018) 8...exd5 (8...Nxd5 9.Nxd5 exd5 10.0-0

We have arrived at positions examined in the Hermes variation.

Variation H3 - Teiresias - 7...Bb4 1.e4 c5 2.Nf3 Nc6 3.d4 cxd4 4.Nxd4 Qb6 5.Nb3 Nf6 6.Nc3 e6 7.Bd3 Bb4

This early pin is seldom played in practice except by IM Vladimir Karasev who is a specialist in this line. Black hopes to ruin White’s pawn structure (after ...Bxc3) while benefiting in the long run from the blocked character of the position. But the surrender of the dark-squared bishop weakens the defense of his kingside.

466

8.0-0 Main alternatives for White are: a) 8.Be3 (this variation mostly arises via the 8.0-0 0-0 9.Be3, move order) 8...Qc7 9.0-0 (9.f4, transposes to the Dionysus variation) a1) 9...a6?!

With a complicated position as in the game Sznapik,A-Boensch,U Stara Zagora 1990. Conclusion Although not a main line, this variation deserves more attention than it has till today. 491

It is rare that White would be fully prepared for it and it gives Black interesting, dynamic play. The last years’ games just confirmed this evaluation.

Variation I - Hermes B33 The starting point of the next diagram identifies the turning point of the Hermes variation, which comes after the initial moves 1.e4 c5 2.Nf3 Nc6 3.d4 cxd4 4.Nxd4 Qb6 5.Nb3 Nf6 6.Nc3 e6 7.Bd3 d6 8.0-0 a6, when White tries an expansion on the queenside with 9.a4

But before we go on, let’s see why I named the variation after one of the most known Gods of the ancient Greek Mythology: Nomenclature Hermes under the Microscope Hermes was the son of Zeus and Maia and was Zeus’ messenger. He was the fastest of all the Gods, wore winged sandals, a winged hat and carried a magic wand. Hermes was the God of thieves and commerce, as well as the guide for the dead who were travelling to the underworld. He invented the lyre, the pipes, the musical scale, astronomy, weights and measures, boxing, gymnastics, and the care of olive trees. White’s early aggression on the queenside is delivering a ‘message’ to the black camp. Black is obliged to accept it and live with it.

Variation I1 - Hermes - 9...? 1.e4 c5 2.Nf3 Nc6 3.d4 cxd4 4.Nxd4 Qb6 5.Nb3 Nf6 6.Nc3 e6 7.Bd3 d6 8.0-0 a6

It seems that White should refrain from playing a4, before Black plays ...a6. 9.a4

494

This is another system where White tries to limit Black’s activity on the queenside. On the other hand, the b4-square becomes ‘weak’. While there are various transpositions I have tried to include all the material in the main lines. 9...Qc7 This seems to be the most precise move, asking White to show his hand.

Alternatives are not easy to find as White has committed himself to the early g4 push. 13.Qf3 Nd7 (13...g5?! 14.e5! dxe5 15.fxg5 hxg5 16.Ne4±; 13...Bb7 14.Qh3 h5!?∞) 14.Nd4 Bb7∞ looks fine for Black. Maybe White should try 13.Qe2 Nb4 14.h3 Nd7, with a complicated Sicilian middlegame. 13...hxg5 14.fxg5 Nd7

And Black’s position is attractive, as in Zigouris,H-Grivas,E Katerini 1992. § Variation I123 - Hermes - 12.Kh1

Black has achieved what he wants, a complicated position with even chances, as in Grujic,Z-Ilic,Z Novi Becej 1994. Conclusion With 9.a4, White stops Black’s expansion on the queenside by the eventual and thematic ...b5, but on the other hand the weakening of the b4-square easily allows Black another thematic move ...Nb4. Black scores well and in general his play is easy and sufficient enough to claim a nice position. Nothing really new was added in the last years and my opinion is that this is not a variation to be afraid of.

547

Variation J - Apollo B33 The starting point of the next diagram identifies the turning point of the Apollo variation, which comes after the placement of White’s dark-squared bishop on d2 after 1.e4 c5 2.Nf3 Nc6 3.d4 cxd4 4.Nxd4 Qb6 5.Nb3 Nf6 6.Nc3 e6 7.Bd3 d6 8.0-0 a6 9.Kh1 Be7 10.f4 Qc7 11.Bd2

But before we go on, let’s see why I named the variation after one of the most known Gods of the ancient Greek Mythology: Nomenclature Apollo under the Microscope Apollo was the son of Zeus and Leto, and his twin sister was Artemis. He was the God of music (he played a golden lyre), and was called the Archer shooting with a silver bow. He was also the God of healing, the one who taught medicine to mankind, the God of light and the God of truth, who cannot tell a lie. One of Apollo’s more important daily tasks was to harness his chariot with four horses and drive the Sun across the sky. He was famous for his oracle at Delphi and people travelled to it from all over the ancient Greek world to learn about the future. His tree was the laurel; the crow was his bird and the dolphin his animal. The 11.Bd2 variation is a ‘gentle’ one, mainly seeking for the ‘truth’, instead of ‘brutally’ chasing the black queen away with the continuation Be3.

It is not necessary to drive the black queen away as Black will ultimately be forced to retreat his queen voluntarily. Thus, in this variation White continues with the useful prophylactic move Kh1, which enables the active advance f4, and develops his dark-squared bishop on d2. The d2-bishop indirectly controls the important b4 square and, moreover, it assists with the e5 advance (after Rae1) as it is not blocking the e-file. Before examining the text, it is useful to mention some examples where White did not develop his dark-squared bishop early: a) 11.Qe1 b5

And Black was fine (½-½) in the game Almasi,Z-Grivas,E Kopavogur 1994. Conclusion

583

With exact knowledge Black can successfully handle White’s preference for the placement of his dark-squared bishop on d2. Nothing really important was added in the last years and my opinion is that Black’s chances are encouraging.

Variation K - Dionysus B33 The Dionysus variation arises after the moves 1.e4 c5 2.Nf3 Nc6 3.d4 cxd4 4.Nxd4 Qb6 5.Nb3 Nf6 6.Nc3 e6 7.Be3 Qc7

But before we go on, let’s see why I named the variation after this ancient God of Mount Olympus. Nomenclature Dionysus under the Microscope Dionysus was the God of fertility and wine, and later was considered a patron of the arts. He invented wine and spread the art of tending grapes. He had a dual nature. On the one hand bringing joy and divine ecstasy, on the other brutal, thoughtless rage thereby reflecting both sides of wine’s nature. If he chose to Dionysus could drive a man mad. No normal fetters could restrain him or his followers. Dionysus was the son of Zeus and Semele. He was the only God to have a mortal parent. His birth by Zeus alone conferred immortality upon him. The 8.f4 variation has a dual nature. It brings joy by its activity, but on the other hand problems could arise by the ruined pawn structure it entails. So, after 8.f4 we have the basic position of the Dionysus variation. White aims to control more space without developing the f1-bishop too early on d3, perhaps even hoping to place it on g2. But before examining the 8.f4 line it is useful to mention some other (than the ‘usual’ 8.Bd3) sideline 8th moves White has tried, although they are not fully recommended. 585

Here the pin is more sensible than in the 7.Bd3 Bb4 variation as White has already placed his bishop on e3 thus having ‘forfeited’ the possibility of Bg5 or Bd2. Another playable continuation starts with 8...d6. After 9.g4, we have a position that in practice is most often reached by a different move order: 1.e4 c5 2.Nf3 Nc6 3.d4 cxd4 4.Nxd4 4...Nf6 5.Nc3 d6 6.Bg5 Qb6 7.Nb3 e6 8.Bf4 Ne5 9.Be3 Qc7 10.f4 Nc6 11.g4 (Sicilian Defense - Sozin Attack). I feel that this is too ‘passive’ of an alternative for ‘Grivas Sicilian’ players, so I would concentrate only on the text. 9.Bd3 The most popular continuation.

17.c4 Hardly satisfactory is 17.h4? d5!µ. White must keep the d5-square under control. 17...Nbd7 18.a4

18...Nc5 18...Qc6!? 19.Nd2 a5∞, or 18...a5, are good alternatives. 19.Nxc5 bxc5 20.h4 h5! 20...Bc6 21.g5 hxg5 22.hxg5 Nd7 23.Kf2, might give White some play. 21.g5 Ng4

617

And the position is unclear. White has a worse pawn structure but Black has a somewhat worse king. R Variation K23 - Dionysus - 12.Kh1 1.e4 c5 2.Nf3 Nc6 3.d4 cxd4 4.Nxd4 Qb6 5.Nb3 Nf6 6.Nc3 e6 7.Be3 Qc7 8.f4 Bb4 9.Bd3 Bxc3+ 10.bxc3 d6 11.0-0 e5 12.Kh1

This prophylactic move is probably White’s best try. 12...Ng4!

618

As White has not yet blocked the centre, 12...h6?!, turned out to be a bad idea: 13.Qe1 b6 14.fxe5 dxe5 15.Qg3 Kf8 16.Nd4 Nh5 17.Qg6 exd4 18.cxd4 Nf6

19.Rxf6! gxf6 20.Qxf6 Rg8 21.Bf4 Qd7 22.Bd6+ Ke8 23.Bb5 Bb7 24.d5 Rc8 25.Rd1 a6 26.dxc6 Bxc6 27.Rd5 1–0 Vouldis,A-Grivas,E Rhodes 1993 - see the analyzed game in the Middlegame Strategy chapter. 13.Bg1 13.Bd2 exf4 14.Bxf4 0-0 15.Nd4 Nge5∞, is a possible alternative. 13...exf4 14.Rxf4 Nge5 15.Nd4

619

15...0-0 Playable is 15...Ng6 16.Rf1 0-0∞, as in Berrocal Farina,J-Cuartas,J Barbera del Valles 2006, or 15...a6 16.Nf5 0-0 17.Ne3 Be6 18.Nd5 Bxd5 19.exd5 Ne7∞ Brantjes,Y-Overeem,M Leiden 2015. 16.Nf5 Looks like the best try. White has gone for 16.Qh5 Ng6! 17.Rf3 Nce5 18.Rg3 Nf4 (18...Qxc3!? 19.Rf1 Qc7 20.Nf5°) 19.Qg5 Ne6 20.Nxe6?! (20.Qd2 Nc5 21.Nf3 Ng6∞) 20...fxe6 21.Bd4 b6³ Liss,E-Grivas,E Rishon Le Ziyyon 1993 and for 16.Qd2 f6 17.Rff1 Qe7 18.Rab1 b6 19.Bb5 Na5 20.Nf5 Bxf5 21.exf5 Rac8³ Gikas,V-Grivas,E Khania 1995, without much success. 16...f6 16...Be6!?, is a novelty waiting to be played! Black looks like doing OK: 17.Qe1 (17.Qd2 f6 18.a4 Bxf5 19.exf5 Rad8³) 17...Ne7 18.Bd4 f6³. 17.Bb5! Transferring the bishop to a better square on b3. 17...Rd8 18.Ba4 Bxf5 18...Be6!? 19.Bb3 Nc4∞. 19.Bb3+ Kh8 620

A suggested novelty to 19...Be6? 20.Bxe6+ Kf8 21.Qh5 Ke7 22.Bd5± Istratescu,A-Atalik,S Bucharest 1995. 20.exf5 d5∞

Black is doing fine. As I have already mentioned, 16...Be6!?, should be tested, where I feel that Black’s position is sound. Conclusion As you can see little new ideas have been played during the last years with the Dionysus variation. Black has found ways to obtain counterplay without difficulties.

621

Variation L - Athena B33 The starting point of the next diagram identifies the turning point of the Athena variation, which appears after the placement of the white queen on e2: 1.e4 c5 2.Nf3 Nc6 3.d4 cxd4 4.Nxd4 Qb6 5.Nb3 Nf6 6.Nc3 e6 7.Bd3 d6 8.Be3 Qc7 9.f4 a6 10.Qe2

But before we go on, let’s see why I named the variation after one of the most known and respected Goddess of the ancient Greek Mythology. Nomenclature Athena under the Microscope Athena was the Greek virgin Goddess of reason, intelligence, arts, and literature. Athena was the daughter of Zeus. She sprang full grown in armory from his forehead and thus had no mother. She was fierce and brave in battle but only in defensive wars. She invented the bridle which permitted man to tame horses, the trumpet, flute, pot, rake, plow, yoke, ship, and the chariot. She was the embodiment of wisdom, reason, and purity. She was Zeus’s favorite child and was allowed to use his weapons, including his thunderbolt. Her favorite city was Athens, her tree - the olive and her bird - the owl. Athena gives her name to this variation as Zeus’s favorite child having a lot in common with the lines of the ‘Zeus’ variation (10.Qf3). Compared to the 10.Qf3 line, this one seems to be ‘virgin’ territory. 622

Variation L1 - Athena - 10.Qe2 1.e4 c5 2.Nf3 Nc6 3.d4 cxd4 4.Nxd4 Qb6 5.Nb3 Nf6 6.Nc3 e6 7.Bd3 d6 8.Be3 Qc7 9.f4 a6 10.Qe2

This is supposed to be more ‘innocent’ compared to 10.Qf3, as now White does not have at his disposal the important option of Qh3. On the other hand, on e2 the queen applies more pressure on the e-file, while preserving the Qh5 possibility for a later stage. If White instead plays 10.0-0 Be7 (10...b5?! 11.Qf3! Be7 (11...Bb7) 12.e5!±), then the possibility of 11.Na4!?

623

Comes to mind. Now Black can continue with 11...Nd7 (11...b5 12.Nb6 Rb8 13.Nxc8 Qxc8 14.Qe2 (14.c3²) 14...Ra8 15.Rf2 0-0 16.g4 e5 17.f5 d5∞ Fedorov,A-Kotov,V St Petersburg 2000) 12.c4 b6 (12...0-0 13.Rc1 b6 14.Nc3 Nc5 15.Bb1 Bb7 16.Nd4 (16.Qh5 g6 17.Qh3∞ Loskutov,O-Neverov,V St Petersburg 1999) 16...Rac8∞ Borawski,J-Olhovik,A Bialystok 2014) 13.Nd4 (13.Qd2 Nc5 14.Naxc5 bxc5 15.e5 dxe5 16.Bxc5

It should be mentioned that the moves 10.Qe2 and 10.Qf3, seem to be the most promising. Another placement of the white queen was seen in Beliavsky,A-Gufeld,E Sukhumi 1972: 10.g4 b5 11.g5 Nd7 12.Qd2

11...b5 In this variation Black’s main idea consists of ...Nb4, ...Nd7-b6/c5 and ...Bb7. White must be ready to answer ...Nb4xd3 with cxd3, as then he can use the opening of the c-file with Rc1. 12.g4 White has tried to do without this move: a) 12.Kb1 Nd7 13.Rhf1 a1) 13...Bb7 with...Nc5 to follow, also seems playable for Black. a2) 13...Nb4 14.Rc1

The main alternative for Black is 14...Nc5?!, when 15.Rhf1! (15.Rhg1 Nxd3 (15...b4?! 16.Nd5! exd5 17.exd5 Nxd3 (17...Na5 18.Nxa5 Qxa5 19.Rge1±) 18.dxc6 Bxc6 19.Qxd3 0-0 20.Nd4± Velimirovic,D-Djukic,Z Svetozarevo 1990) 16.cxd3 Rc8 17.f5 Qd7∞), transposes to the note above.

15.Rc1 A logical approach - White can initiate mutual play over the c-file. All other tries transposes to the above lines. 15...Nc5 16.Rhe1 In the ‘old’ times 16.Rhg1, was the main try, but nowadays the computer engines have found good ways for Black to create dangerous counterplay keeping him in the game:

Another way to go is by 16.Nd4 0-0 17.h4 d5 18.e5 Ne4∞ Roseneck,J-Oberhofer,C Wuerzburg 2019. Usually in similar cases Black should delay castling as long as it is possible.

This is a logical idea, preparing an assault on the queenside. Moves like ...Bb7 or ...0-0 can wait for the proper moment. Also, Black retains the option of ...Bd7, which now does not block the b-file and at the same time overprotects the valuable e6–square. 14.Rc1 An interesting and useful move, getting ready for the opening of the c-file and at the same time vacating a square for the c3-knight on d1.

14...Na4 14...Bd7!?, is quite interesting. Black prefers to wait until the right moment for ...Na4 and ...Nb4. Also, it must be mentioned that it is very important for Black to place a knight on e5 after a possible f5 by White. After 15.g5 0-0, chances seem to be equal in this unclear position. Black is ready for 16.f5 Na4∞.

15.Nd1 15.Nxa4 bxa4 16.Nd2 (16.Nd4?! Nxd4 17.Bxd4 e5³) 16...a3 17.b3 Nb4∞, should be great for Black, while; 15.Bd2 Nxc3+ 16.Bxc3 e5∞, looks like a better version than above. 15...Nb4 Black can also think of 15...0-0 16.c4 b4

658

With an unclear position, as in Cela,A-Grivas,E Athens 1995. Conclusion More or less, it seems that Black can be satisfied with unclear positions, full of chances for both sides. The placement of the white queen on e2 doesn’t seem to be so dangerous.

Variation M - Zeus B33-B88 Here is the main line which I called the Zeus variation. The starting point of the next diagram identifies the turning point of the Zeus variation, which comes after the following moves: 1.e4 c5 2.Nf3 Nc6 3.d4 cxd4 4.Nxd4 Qb6 5.Nb3 Nf6 6.Nc3 e6 7.Bd3 d6 8.Be3 Qc7 9.f4 a6 10.Qf3 Be7

In this position White can castle on both sides, thus determining the two main lines of the present variation. But before we go on, let’s see why I named the variation after the top God, the God of Gods, of the ancient Greek Mythology. Nomenclature Zeus under the Microscope Zeus was the God of the sky and ruler of the Olympian Gods. Zeus overthrew his father, Cronus, and then drew lots with his brothers Poseidon and Hades. Zeus won the draw and became the supreme ruler of the Gods. He was the lord of the sky, and his weapon was the thunderbolt, which he hurled at those who displeased him. He was married to Hera but was famous for his many affairs. He was also known to punish those that lie or break oaths. He was the rain God and the cloud gatherer, who wielded the terrible thunderbolt. His breastplate was the aegis, his bird - the eagle and his tree - the oak. He was represented as the God of justice and mercy, the protector of the weak and the punisher of the wicked. The main and the most critical line of the ...Qb6 variation had to be named after the supreme ancient 660

Greek God.

Variation M1 - Zeus - 10.Qf3 1.e4 c5 2.Nf3 Nc6 3.d4 cxd4 4.Nxd4 Qb6 5.Nb3 Nf6 6.Nc3 e6 7.Bd3 d6 8.Be3 Qc7 9.f4 a6 10.Qf3

The white queen’s placement on f3 is more aggressive, as it introduces the extra attacking possibility Qh3, or pressure along the h1-a8 diagonal. 10...Be7

An alternative move is 10...b5. After 11.0-0, he can choose: a) 11...Be7?!

It is more in the spirit of the variation to delay the ...b4 advance, as the placement of the knight on b4 (to keep the d3–bishop under control) is a better plan.

Black gets the bishop pair and stops any attacking ideas against h7.

§ Variation M113 - Zeus - 12.Rae1 1.e4 c5 2.Nf3 Nc6 3.d4 cxd4 4.Nxd4 Qb6 5.Nb3 Nf6 6.Nc3 e6 7.Bd3 d6 8.Be3 Qc7 9.f4 a6 10.Qf3 Be7 11.0-0 0-0 12.Rae1

A typical and good move, which completes White’s development. Here Black must decide between 12...Nb4, 12...Nd7, 12...Rb8 and 12...b5. Note that 12...Re8 13.g4 Nd7 14.g5 Bf8 15.Qf2 (15.Qh5 g6 16.Qh4 b5 (16...Nb4 17.Rf3 b5 18.Ref1 Nxd3 19.cxd3² Tuma,J-Svoboda,V Sec u Chrudimi 2008) 17.Rf3 Qd8!∞ Maslak,K-Vavra,P Pardubice 2000; 15.Nd4 g6 16.Qf2 b5 17.Nxc6 Qxc6 18.f5∞ Stoilov,A-Nikolov,M Plovdiv 2004) 15...b5

A fully playable and reasonable alternative if Black wants to avoid other sharp lines. The drawback is that it allows the recentralization of the b3-knight.

As the endgame after 20.gxh6 Qxh4 21.Rxh4 Kh7 22.Rh3 Rac8

The position seems nice for Black, White’s attack through the h-file is not that easy anymore. The position is unclear and offers equal chances. It must be mentioned that Black should play 19...h6!, with the same ideas, but the latter is more accurate as it avoids future sacrifices on h5. Now White should go with 20.f5!, when Black should be very careful: a) 20...b4? 21.Ne2 Nce5 (21...Nde5 22.Nf4 Nxd3 23.cxd3 exf5 24.exf5 Ne5 25.Nxh5+–) 22.Nf4 Bg7 23.fxg6 fxg6 24.Nxg6!+–. b) 20...Nb4? 21.Be2 exf5 22.Bxh5!

Black avoids the ‘threat’ 13.e5, by removing the rook from the h1-a8 diagonal. But this rook move has more point when White has already played a3. 13.g4 The most common and dangerous continuation. With the text move White looks to achieve a good version of the g4–advance, where ...Rb8, isn’t that useful. Alternatives are: a) 13.Qg3

The critical position, where Black’s main defense/counter-attack relies on an extraordinary sacrifice involving ...Ne5, with which Black wants to take advantage of the h1-a8 diagonal by lining up his queen and bishop by ...Qd5 and ...Bb7.

After this move Black is almost forced to castle kingside entering a complicated battle. 13.Kb1 White must avoid Rxd3 in almost all cases of Black playing ...Nxd3.

This is the key position for this variation. A complicated and tense battle is on the way where much depends on which way the king will move. White will try to create threats against the black king with the use of a kingside pawn advance, supported mainly by the heavy pieces. Black must defend against this plan, trying at the same time to create his own threats on the queenside. In general, exchanges of heavy pieces favors Black, as a possible attack is restrained and the endgames seem to be better for him due to his potential bishop pair (after ...Nxd3). White’s main tries are 16.Nd4, 16.Rhf1 and 16.Rhg1.

A more solid continuation, where Black retains the option to castle short or long (mostly with ...Bd7 instead of the usual ...Bb7 as the e6-square gets better protection) and proceeds to ‘attack’ the c3846

knight with ...Nb6-a4. On the other hand, I must admit that Black loses time with this maneuver, and it is not clear that this is a better try than the MI1 lines. In the game Tsarouhas,V-Grivas,E Athens 1998, Black had delayed ...Be7 via the move order 1.e4 c5 2.Nf3 Nc6 3.d4 cxd4 4.Nxd4 Qb6 5.Nb3 Nf6 6.Nc3 e6 7.Bd3 d6 8.Be3 Qc7 9.f4 a6 10.Qf3 b5 11.0-0-0 Nd7 12.Kb1 Nb6 and was successful after the optimistic 13.Rhe1 Na4 14.Nd5?!

Conclusion Important games have been played during the last twenty years. Fierce battles have been contested and the evaluation remains the same: Black is ‘surviving’ (alive and kicking!) but with very concrete and accurate play. There are a lot of transpositions, and some games are noted twice, but there was hardly any other choice to make things more understandable. It is also understandable that both sides are really scared of these long and quite complicated variations, and they prefer more simpler things. Rightly this variation is considered to be the Zeus of the Olympus Mountain.

Chapter 2 - Typical Middlegame Strategy Knowing a good piece of your opening’s theory to a sufficient depth is a good start. But this alone is not enough to gain and increase a significant advantage. The knowledge of certain plans, maneuvers, repeated motifs, etc, is an essential piece of opening knowledge, as the journey continues via what we call middlegame theory. Yes, middlegame (and endgame) theory does exist. The great difficulty in approaching it lies in the fact that it does not follow absolute and clear-cut paths, but involves deep research in the ideas and logic by which specific types of positions are treated. Moreover, unlike opening theory, the theory of the middlegame (and the endgame) does not change rapidly based on modern developments and remains almost intact through the years. In middlegame theory we are obliged to study various or similar types of positions with specific strategic and tactical attributes in order to understand the underlying ideas and be able to employ them in similar situations. Besides, while many chess players have studied these topics and acquired knowledge, it is the application of this knowledge in practice that helps differentiate between them. True, chess is not a simple activity, but it becomes so much more attractive when we acquire this knowledge. In view of the above, any chess player who wishes to follow a chess career or simply become a better player must refrain from the commonplace and assume a different approach. He must develop a good understanding of middlegame (and endgame theory), so as to be able to proceed in a proper way after his chosen opening has reached its conclusion. And we must keep in mind that the most important asset is the pawn structure. This is what guides us to understand what to do in the middlegame and even in the endgame!

A well-known theoretical position. Here I played a prepared novelty. 16...Rfc8? In 1995, without any computer help, I believed that this was the only good move in this position, and a novelty at the time. Only this move can guarantee the viability of Black’s position. All other tries in this position have led to disaster. Nowadays I know that this is quite a bad move. Black is obliged to play 16...Nxd3! 17.cxd3 b4! 18.Ne2 Rfe8! 19.Nbd4 (19.f5 exf5 20.exf5 Ne5 21.f6 Bf8∞; 19.Ned4 e5 20.Nf5 exf4 21.Rc1 Qd8 22.Bxf4 Ne5 23.Qg3 Kh8∞) 19...e5 20.Nf5 Rac8 21.Rc1 Qd8 22.Rxc8 Bxc8

With a very unclear position where both sides have their chances. But how did I come up with such a 867

weird move as 16...Rfc8? It was based on quite a sophisticated plan which involves both black rooks playing down the c-file producing a powerful attack. Unfortunately, today I know that my general idea was correct, but fails due to certain tactics! It makes me feel sorrow for my bad piece of analysis. 17.Rd2?

White defends against the threat of 17...Nxd3 18.cxd3 b4, while at the same time preparing to double his rooks on the g-file. This, along with the idea Nd1-f2-g4-h6+, will be the main theme of White’s attack. Another possibility is 17.Nd4 e5! 18.Nf5 Bf8!, with unclear consequences. But as my faithful engine alarmed me (many years after by the way...) 17.f5!

19.g6! (again, White has no time to recapture the knight: 19.cxd3? Ne5 20.Nd4 Qd7! (20...Bf8 21.Nce2 Re8 22.Rg3 Rac8 23.Nf4 b4 24.g6 fxg6 25.fxg6 Nxg6 26.Rxg6 hxg6 27.Nxg6 Rxe3 28.Qxe3± Kotronias,V-Grivas,E Athens 1995) 21.Ne4 Bxe4 22.dxe4 g6∞) 19...fxg6 (19...hxg6 20.fxg6 fxg6 21.Qe6+ Kf8

22.Qxg6! (22.Rxd3 Nf6 23.Rxg6±) 22...Bf6 23.Bh6!+–) 20.fxg6 Nf6 21.Rxd3 hxg6 22.Rxg6+–.

869

17...Nxd3 Back to business again! 18.cxd3 b4! 19.Nd1 Maybe White could choose 19.Ne2, although Black looks quite nice after 19...Nc5 20.Nbd4 (20.Rc1 a5³) 20...b3³. 19...a5!

The point behind Black’s 16th move. If the attack is going to succeed then all of Black’s pieces must participate. It now becomes clear why Black chose the f-rook: the a8-rook participates both in attack and in defense (it will soon appear on a5), creating dangerous threats, while the advance of the apawn will weaken White’s king. 20.Nf2 Forced, due to the threat 20...a4 and 21...Qc1#. 20...a4?! 20...e5!, is probably best: 21.f5 a4 22.Na1 b3!, with a black initiative. But I had my own idea, and I was stuck with it... 21.Nd4 Ra5!

870

The main part of the plan. Unsatisfactory is 21...e5?! 22.Nf5 Bf8 23.Ng4 and White has more dangerous threats, or 21...a3 22.b3 e5?! 23.Nf5 Bf8 24.fxe5 Nxe5 (24...dxe5 25.Nh6+! gxh6 26.gxh6+ Kh8 27.Qg3 Nf6 28.d4! Ra5 29.dxe5 Rxe5 30.Bd4 Rce8 31.Ka1±) 25.d4 Ng6 26.d5 Ba6 27.Bd4 Kh8 28.Qg3². The black rook on a5 is moved to c5 and becomes the main attacker (through the c-file) and the main defender (through the fifth rank) of Black’s position. And the Oscar goes to this rook! 22.Ng4? It seems that White was stuck with his own plan as well! Two optimists were just ignoring the facts! Again 22.f5!, was best: 22...exf5 (22...Rc5? 23.Re2 a3 24.fxe6 Bxg5 25.exf7+ Kh8 26.Nb3 (26.Ne6?? Rc1+ 27.Rxc1 Qxc1+ 28.Bxc1 Rxc1#) 26...Rc2 27.f8=Q+ Nxf8 28.Qxc8 Rxb2+ 29.Rxb2 Qxc8 30.Rc2 Bxe3 31.Rxc8 Bxc8 32.Rg3 Bf4 33.Rf3 g5 34.h4±) 23.Nxf5 (23.exf5 Ne5 24.f6 Rc5 25.Re2 Bf8∞) 23...Nc5 24.Rc1 Qd8 25.d4 Nd7 26.Rxc8 Bxc8 27.Qg3 b3!∞. 22...Rc5 23.Rdg2 Defending c1 and enforcing the g-file, preparing the sac Nh6+. 23...Ba6! All of Black’s pieces are active and create multiple threats, denying White a respite to further his own aims. 24.Bd2 a3!

871

White’s position becomes critical. He now decides to complicate matters, hoping for salvation in an attack against the black king. After all, this is what he had prepared with his last moves... 25.Nh6+?! Naturally, 25.bxa3? bxa3, leaves the king very exposed, while 25.b3? Rc3!!

is also very troublesome: 26.Bxc3 Qxc3 27.Rd1 Qxd4–+. The position is extremely difficult to assess, and this where we do not relay on evaluation, but on tactical sequences. The last alternative was 25.f5, which leads to extreme complications, visible only by a chess engine: 25...Ne5 26.Nxe5 (26.fxe6? Bxd3+–+) 26...dxe5 27.g6 fxg6 28.fxg6 h6 29.Bxh6! (29.Qxe6+? Kh8 872

30.Qxa6 exd4 31.Bxh6 Bd6!! 32.Bd2 Bf4µ) 29...Bxd3+

30.Nc2!! (30.Qxd3? exd4–+) 30...Bh4!! (30...Rxc2? 31.Qxe6+ Kh8 32.Bxg7+ Kxg7 33.Qf7+ Kh6 34.Qh7#; 30...Bxc2+? 31.Rxc2 Rxc2 32.Qxe6+ Kh8 33.Bxg7+ Kxg7 34.Qf7+ Kh6 35.Qh7#) 31.Qxd3 gxh6 and Black’s chances seem to be better... You may rest assured that both opponents did not see any of this during the game... 25...gxh6

26.g6

873

After 26.gxh6+ Kh8 27.Qg3 Bg5!! (once again the star rook comes in handy!) 28.fxg5 Rc2 (28...Ne5–+) 29.bxa3 bxa3, White is dead lost. 26...fxg6! 27.Rxg6+

If 27.Nxe6, then 27...Qc6–+. Also, 27.Qxe6+ Kh8 28.Qxe7 Bxd3+ 29.Ka1 Rc1+!, is decisive as well. 27...Kh8! 27...hxg6? 28.Rxg6+ Kf7 29.Qxe6+ Ke8 30.Rg8+ Nf8 31.Rxf8+ Kxf8 32.Qxh6+ Ke8 33.Qg6+, would make White happy, as he could escape with a draw. 28.Nxe6?! 28.Qxh6?? Bxd3+ 29.Ka1 Rc1+!, leads to mate, but White might have tried 28.Rxh6 Nf6! 29.Nxe6, where Black had to find the extremely elegant (and only move) 29...Rg5! (the star rook again!) 30.Nxc7 (30.Rc1 Qxc1+! 31.Bxc1 Rg1!–+) 30...Rxg1+ 31.Kc2 Rxc7+ 32.Kb3 Rd1–+.

874

28...Rh5!! A brilliant tactical shot by the star rook, clearing the way for the queen to reach c2. White is lost in all variations. 29.Rg8+ The last - but inadequate - try. Otherwise: 29.Qxh5 Qc2+ 30.Ka1 Qxb2#, or 29.Nxc7 Rxh3 30.Re6 Bxd3+ 31.Ka1 Bf6–+. 29...Rxg8 30.Rxg8+ Kxg8 31.Qg3+ Rg5! Another easy but nice tactical shot, once again by the star rook! 32.fxg5 Qb6 And Black emerged from the complications a piece-up. 33.g6 White prolongs the game only because of the mutual time-trouble, but the result never comes into doubt. 33.gxh6+ Kf7, was also winning for Black. 33...Bf6! 34.gxh7+ Kxh7 35.Qh3 Kg8 36.Qg4+ Kf7 37.Nf4 Nf8 38.Qh5+ Kg8 39.Qd5+ Kh8 40.Qf7 Bg7 41.Qe8 Qg1+ 42.Kc2 axb2 43.Be1 b1=Q+

875

Here White’s flag felled (no extra 30 seconds per move in this era), we restored the last moves that were not recorded by either player and White simply resigned as 40 moves had been completed. 0–1 Cela Altin : Grivas Efstratios B33 Kalavrita 1997 1.e4 c5 2.Nf3 Nc6 3.d4 cxd4 4.Nxd4 Qb6 5.Nb3 Nf6 6.Nc3 e6 7.Be3 Qc7 8.f4 Bb4 9.Bd3 Bxc3+ 10.bxc3 d6 11.0-0 e5 12.f5 h6 13.Qf3 b6 14.Qg3 Kf8 15.Bc1 Nb8

876

Black seems to be doing more than fine; he has lost his castling rights, but the white pawn structure is rather weak and under heavy and constant pressure. 16.Ba3 Black won in Rogers,I-Avshalumov,A Belgrade 1989, after 16.a4 Nbd7 17.a5 Bb7 18.axb6 axb6 19.Rxa8+ Bxa8µ. 16...Nbd7 17.Rae1 Nc5 18.Qh4 Bb7 19.c4 Qe7! Black has developed harmoniously and as noted beforehand, is ready to apply pressure on White’s weak pawn structure. Of course, he still has some problems with the placement of his king but, as White cannot approach him, there is no immediate danger.

20.Nd2 Rc8 21.g4 Nfd7! Stopping the rather dangerous 22.g5 advance. 22.Qg3 Ke8! An excellent idea! The black king finds a safe haven on the queenside, while White is lacking a dangerous plan. The balance is clearly shifting in Black’s favour. 23.Nb1 Na4 Black even prevents White’s simple plan of Nc3-d5, although it wouldn’t offer anything special. 24.Bc1 Kd8 25.g5?! 877

Further weakening the pawn structure. White’s only plan was the advance of his kingside pawns, starting by 25.h4. 25...hxg5 26.Bxg5 f6 27.Bd2 Kc7 28.Rf2

28...Rcg8! Black has completed the safeguarding of his king and now prepares his plan of counterattack against the white monarch. White is unable to react as his pieces lack harmony and no plan is available to him. 29.Kh1 g6! 30.fxg6 Nf8 31.Qf3 Rxg6 32.Nc3 Nxc3 33.Bxc3 Ne6 34.Bd2 Qg7 34...Nd4! 35.Qe3 f5 36.Bc1 f4 37.Qd2 Qh4–+, looks already like curtains. 35.Rg2 Forced, otherwise the threatened 35...Rg8, would be decisive.

878

35...f5! 36.Reg1 Rxg2 Again 36...fxe4! 37.Rxg6 Qh7!, would have finished the game shortly... 37.Rxg2 Qh7 Black’s position is won. His positional strength and tactical superiority are crushing. In other words, even if Black fails to mate then he will win the ending! During the game I was wondering why my opponent was continuing the battle. 38.Qe3 Nf4! 39.Rf2 fxe4? 39...Nxd3! 40.cxd3 fxe4, would end the game immediately: 41.dxe4 Bxe4+ 42.Kg1 Rg8+ 43.Kf1 Bd3+ 44.Ke1 (44.Re2 Qxh2–+) 44...Rg1+ 45.Rf1 Rxf1#. 40.Bf1 Qg6 41.Be1! White regroups his remaining pieces, simply aiming to trouble Black as much as possible while hoping for mistakes. 41...Rg8 42.Rd2 Rf8 43.Bg3 Nh5 44.Bg2 Nxg3+ 45.hxg3 Rh8+ 46.Kg1 Qh7 47.Rf2 Qg6

879

48.a4! While Black is wandering around aimlessly in his won position, White uses all his forces to attack the black king which is White’s only approachable target. 48...Rg8 48...a5 49.c3, aiming for Rb2, when White gets some counterplay. 49.a5! Bc6 50.Kh2 Kb7 51.axb6 axb6 52.c3! Kc7 53.Rb2 Rb8

880

The first good sign for White, having forced Black to turn to defensive duties. 54.Re2 Qe6 55.Qg5 Rg8 56.Qh4 Qxc4? Instead, 56...Qd7! 57.Kg1 Qg7–+

was good enough but Black was getting dizzy. 57.Qh7+ Bd7 58.Rxe4 Qa2 59.c4? 59.Rh4!, was simply unclear! 59...Rf8 60.Rh4! Suddenly White’s threats have grown (61.Qe4 and 62.Rh7!). 60...Qe2

881

61.c5! A good move, simply from a practical point of view, based on the mutual heavy time trouble (no increment - no extra time). Although best was 61.Re4 Qc2 62.Rh4 Rf2 63.Qxc2 Rxc2µ. 61...Rf2?! 61...bxc5! 62.Ra4,

looks like extremely risky for Black but still wins after 62...Rf2! 63.Ra7+ Kb6 64.Rb7+ Ka6 65.Ra7+ 882

(65.Kh1 Qd1+ 66.Kh2 Qf3–+) 65...Kxa7 66.Qxd7+ Kb6 67.Qxd6+ Kb5 68.Qc6+ Kb4 69.Qb6+ Qb5–+. 62.cxb6+ Black wins as well after 62.cxd6+ Kxd6 63.Rh6+ Kc5 64.Qe7+ Kc4 65.Rh4+ Kb3 66.Qb4+ Ka2–+. 62...Kxb6 63.Qb1+ Bb5 64.Qg1

64...Qb2? Black lost his calm and missed the simple 64...Qf1!, after which he would win without much effort. In any case, White has done his best, constantly creating problems and threats. Black has consumed a lot of time and was already facing serious time trouble. The next few moves were played in a flash. White, having the psychological advantage since he practically had gone to hell and back, did not encounter any difficulties in gaining victory! A triumph of persistent defense and faith in the position’s hidden possibilities for White. At the same time, a deserved punishment for the arrogance and ‘certainty’ that Black completely unjustifiably displayed. Alternative win could be found in 64...Bc6 65.Qb1+ Ka6 66.Qa1+ Qa2–+. 65.Kh1 Ka5? 65...Qc2, was still winning. 66.Qe1+ Qd2? 66...Rd2 67.g4 Ka6µ. 883

And Black’s flag felled a move before he got mated. What a sad story. 1–0 Kofidis Andreas : Grivas Efstratios 885

B33 Athens 2000 1.e4 c5 2.Nf3 Nc6 3.d4 cxd4 4.Nxd4 Qb6 5.Nb3 Nf6 6.Nc3 e6 7.Bd3 d6 8.0-0 a6 9.Be3 Qc7 10.f4 Be7 11.Qf3 0-0 12.g4 b5 13.g5 Nd7 14.Qh5 Bb7 15.Rf3 g6 16.Qh6

The critical position where Black’s main defense/counter-attack relies on the extraordinary sacrifice involving ...Ne5, with which he wants to take advantage of the h1-a8 diagonal by lining up his queen and bishop by ...Qc6/d5 and ...Bb7. 16...f5! 17.exf5 exf5 18.Nd5 If 18.Nd4? Nxd4 19.Bxd4,

886

then 19...Ne5!, is strong. 18...Qd8

19.Nd4 One of the many white options here. 19...Nxd4 19...Nc5?, is simply bad: 20.Nxf5 (20.Rh3 Rf7 21.Nxc6 Bxc6 22.Bd4+–) 20...Rxf5 21.Bxf5 Bf8 887

22.Qh4+–. 20.Bxd4

20...Rf7 Possible is 20...Ne5 21.Rh3 Rf7!, when White should not be greedy: 22.fxe5? dxe5 23.Nxe7+ Rxe7 24.Bc3 (24.Be3 Qd5 25.Kf2 e4 26.Bf1 f4–+) 24...Qd5 25.Rg3 Qh1+ 26.Kf2 Qxa1 27.Rg1 Qxa2 28.h4 Qd5 29.h5 b4 30.hxg6 bxc3 31.gxh7+ Rxh7 32.Qg6+ Rg7 33.Qb6 Qd4+ 0–1 Khachiyan,MGrivas,E Inter. 2008. 21.Nxe7+ Rxe7 22.Re3! Ne5!

888

Black’s main idea. Bad was 22...Qf8?! 23.Qxf8+ Kxf8 24.Rxe7 Kxe7 25.a4², as only White has winning chances. I have to confess that this was home preparation. 23.Qh3 Maybe White should opt for 23.Be2!? Qd7! 24.fxe5 dxe5 25.Bc3 Qc6 26.Rf3 b4! 27.Be1 Qe4 28.Kf1 Qxc2°, where Black’s compensation (look at the great central pawn phalanx and the monster on b7) is great but nothing is clear-cut. 23.fxe5? dxe5, ...Qd5 or ...Qb6, will confirm. 23...Ng4

889

And suddenly the poorly placed d7-knight has been improved to the fantastic g4-square, assisting the black attack. But it can be easily lost as well after an eventual h3. 24.Rxe7 24.Re2!?, was another choice but it simply transposes after 24...Qe8 25.Rxe7! (25.Rae1 Qc6 26.Kf1 Qh1+ 27.Bg1 Rxe2 28.Rxe2 Bf3 29.Re6 Kf7 30.Re1 Kf8! 31.Qg3 Re8 32.Rxe8+ Kxe8³) 25...Qxe7 26.c3 Re8 27.Bf1 Qe4 28.Bg2 Qxg2+ 29.Qxg2 Bxg2 30.Kxg2 Ne3+ (30...Re2+ 31.Kg3 Rxh2 32.b4 Rd2 33.Kf3°) 31.Bxe3 Rxe3 32.Kf2 Re4 33.Kf3 Kf7 34.Rd1 Ke6 35.a3 d5=. 24...Qxe7 25.Qf1? White was probably under clock pressure due to my 22nd move and failed to find the best continuation with 25.c3 - see the notes above. 25...Qe6 25...Re8 26.h3 Qe6!, was maybe even better! The b7-bishop is worth its weight in gold and the potential battery with the black queen on the long diagonal is lethal. 26.c4! The only move to stop the coming ...Qd5. White fights well, but unfortunately his position is beyond repair; Black’s threats are simply too strong. 26...Re8 27.Rc1

890

27...Kf8! A cool move! Now Black threatens to capture on c4 and place his queen on d5 or e4, winning. 28.b3 28.Qh3, loses to 28...Qe7! 29.cxb5 axb5 30.Rd1 Ba8! (threatening...Qb7) 31.Bf1 Rc8 (31...Qe4 32.Bg2 Qe2 33.Rf1 Qd2 34.Bb6 (34.Bc3 Qxg2+ 35.Qxg2 Bxg2 36.Kxg2 Ne3+–+) 34...Qxb2–+) 32.Bg2 Qe2 33.Rf1 Qd2–+. 28...bxc4 29.bxc4

29...Qd7! While d5 and e4 are covered, c6 isn’t! 30.Rb1 After 30.h4, Black can further improve his knight: 30...Ne3! (30...Qc6 31.Qh3µ) 31.Qh3 Ng2!–+. What a great future for the previously passive d7–knight! 30...Qc6 31.Rxb7 White avoided mate but he lost material... 31...Qxb7 32.h3 Qb4! And White resigned due to the coming 33...Re1. 891

11.Qe1 White’s choice is no problem for Black. Usually here we see 11.Qf3, 11.Bd2, 11.Be3, or 11.a4. The famous Ukrainian GM prefers a more solid and out-of-main-theory battle. 11...b5 12.a4 Technically a novelty. Another try is 12.Qg3 b4 13.Ne2 0-0 14.Nbd4 Nxd4 15.Nxd4∞ Kosmac,BGombac,J Rogaska Slatina 1998, or 12.Ne2 Bb7 13.Ned4 Nd7 14.Nxc6 Bxc6 15.Nd4 Bb7∞ Cerny,D-Stastny,J Czech Republic 2018. 12...b4 13.Nd1 0-0 Black can usually delay the development of his light-squared bishop, to see where it is better placed. 14.a5

892

14...e5! A typical Sicilian central advance. 15.Ne3 White could think of 15.f5 d5 16.exd5 Nxd5 (16...Nd4!? 17.Nxd4 exd4 18.Qh4 Bb7∞) 17.Ne3 Nf6 18.Nc4 Bb7∞. 15...exf4 16.Nc4 Be6 17.Bxf4 Nd7?! A rather passive move. Natural and good was 17...Ne5 18.Nxe5 dxe5 19.Be3 Nd7∞. 18.Qg3 Nce5 19.Nxe5 Nxe5 20.Bxe5?! White returns the favour. He should play 20.Nd4! Bd7 21.Bh6 Ng6 22.Bd2². 20...dxe5 21.Nd4 Bc8!

893

22.b3?! White should have tried 22.Nf5, when after 22...Bxf5 23.Rxf5 f6 24.b3 g6, an equal position will be on the board. 22...Bc5!

Now Black will preserve his bishop pair, while White’s attack is weak. 23.Nf3

894

23.Nf5 f6 24.Bc4+ Kh8 25.Rad1 g6 26.Nh4, transposes. 23...f6 24.Bc4+ Kh8 25.Rad1 White cannot stay put protecting his a5–pawn for ever, so he sacrifices it for a potentional attack. 25...g6 26.Nh4

26...Ra7! The black rook is ready to first come to the defense and then help the counter-attack. The c8-bishop can still wait - there is no better square for the time being than its original! 27.Rd3?! Quite optimistic. White should have opted for 27.Nf3 Bb7 28.Bd5 Bc6³. 27...Qxa5

895

Material up and the bishop pair. What more could you ask? 28.Qe1 Rg7 29.Qd2 Qc7 30.Rd1 Be7 Protecting all entrance squares on the d-file - where is White going? 31.Qh6

31...f5! The counter-attack begins. 896

32.exf5 gxf5 33.Rd6?! White has nothing to lose, so he plays his hand, but objectively better was 33.Rg3 Bxh4 34.Qxh4 a5µ. 33...Bxh4?! I was in time trouble, and I decided to play it safe. My engine confirms that I should have played 33...Bxd6! 34.Rxd6 Rd8!

with a winning position. 34.Qxh4 Bb7 35.R6d2 Qe7? Again, a safe decision in time trouble. Better was 35...f4 36.h3 f3 and White is collapsing. 36.Qxe7 Rxe7

897

37.Rd7! Now White has some compensation due to his active pieces. 37...Rxd7 38.Rxd7 Be4! 39.h4 Or 39.Kg1 Rc8 40.Kf2 Bxc2 41.Rd5 e4µ. 39...Rf6 40.Rd8+ It was a bit better to keep the black king on his first rank, but Black will win after 40.Kh2 Rg6 41.g3 Bxc2 42.Rd5 f4 43.gxf4 exf4 44.h5 Rf6. 40...Kg7 41.Rg8+ Kh6

898

42.Bd3!? A clever try as rook endings are always difficult to handle with accuracy. 42...Bxd3 43.cxd3 Rd6 44.Re8 Rxd3 45.Rxe5 Rxb3 46.Rxf5 Ra3 Time trouble was over, and my two queenside connected pawns will carry the day. But still White has some counterplay to hope for salvation! 47.g4! Ra2?! Played on a general idea - to cut-off the white king. But the accurate 47...Kg7! 48.Rd5 b3 49.Rd7+ Kf6 50.Rb7 a5 51.Kg2 a4, was curtains. 48.Rf6+ Kg7 49.Rb6 a5 50.g5 Rc2! The white pawns should be attacked - they can simply be too dangerous! 51.h5 Rc5! 52.h6+ Kf7

899

And I thought that he would resign here, but the fighting spirit continuous till the bitter end. 53.g6+! hxg6 54.Kg2 Rh5 55.Rb7+ Kf6?! Making my life difficult. Simple was 55...Kg8! 56.Rg7+ Kh8 57.Rxg6 Rb5 and it’s over ... 56.h7 b3

57.Ra7?! White had to go for 57.Rxb3 Rxh7 58.Rb6+ Kg7 59.Ra6 Rh5 and test Black’s knowledge. According 900

to the tablebases, Black wins in approximately 40 moves from here. 57...b2! 58.Rxa5!? b1=Q 59.Rxh5

Luckily Black has a forced win here. 59...Qe4+ 60.Kf2 Qf4+ And White resigned due to 61.Ke1 Qe3+ 62.Kf1 Qf3+ 63.Ke1 Qxh5–+. 0–1 Nunn John : Grivas Efstratios B33 Athens 1991 1.e4 c5 2.Nf3 Nc6 3.d4 cxd4 4.Nxd4 Qb6 5.Nb3 Nf6 6.Nc3 e6 7.Bd3 Be7 8.Be3 Qc7 9.f4 d6 10.00 a6 11.Qf3 0-0 12.Rae1 b5 13.g4 Bb7 14.g5 Nd7 15.Qh5

901

A well-known position where Black has to go with 15...g6. 15...Nb4? 16.Rf3 Nxd3 A novelty during those computer free years. 16...g6? 17.Qh6 f5 18.exf5 exf5 19.Rh3 Rf7 20.Bd4! Nf8 (20...Ne5 21.fxe5 dxe5 22.Bxf5!±) 21.Bxf5!± Chandler,M-Gufeld,E Dortmund 1983. 17.cxd3? White clearly has the upper hand after the natural 17.Rh3! h6 18.cxd3 Rfe8 19.Rg3!± and not by Nunn’s suggestion of 19.Nd5? exd5 20.Bd4 Bxg5! (20...Ne5 21.gxh6 g6 22.h7+!²) 21.Bxg7 (21.fxg5 Ne5!∞) 21...Kxg7 22.fxg5 Re6 (22...Rh8? 23.gxh6+ Kf8 24.Rf1 Ne5 25.d4±) 23.gxh6+ Kh8 24.Qxf7 Rg6+!∞. 17...Rfe8 18.Ref1?! More correct is 18.Bd4! Rac8, with a slight edge for White but not 18...g6? 19.Qxh7+!+–, or 18...Nf8? 19.f5! exf5 20.Rxf5 g6 21.Qh6 Ne6 22.Rxf7!+–. 18...g6 19.Qh6

902

19...Bf8! Black can try 19...f5!? 20.Rh3 (20.exf5? Bf8 21.Qh4 exf5µ) 20...Nf8, but White gets a more pleasant position after 21.Rc1!². 20.Qh4 Bg7 21.Rh3 h5? 21...Nf8, is somewhat passive but necessary: 22.Bd4 (22.Nd1 Rac8 23.Nf2 Qc2³) 22...Bxd4+ 23.Nxd4 Rac8∞. 22.gxh6 Bf6 23.h7+? The white pawn on h7 is the black king’s best cover! White should play 23.Bd4! Bxd4+ (23...e5? 24.fxe5! Bxh4 25.h7+!+–) 24.Nxd4 Qb6 25.Nce2±. 23...Kh8 24.Bd4 Bxd4+ 25.Nxd4 Qb6 26.Nce2

903

26...Rac8 26...e5?, is alluring but mistaken: 27.fxe5 dxe5 28.Rxf7!+–. 27.Qh6 Nf6! The correct defense, as the active 27...Rc2? 28.Kh1 Rxb2 29.Nxe6! fxe6 (29...Rxe6 30.Qg7+!+–) 30.Qxg6 Qd8 31.Rg1, intending 32.Qg8+, loses for Black. Likewise, 27...d5? 28.e5 Rc2 29.Kh1 Rxb2 30.f5! exf5 31.e6! Rxe2 32.exf7 Rf8 (32...Qxd4 33.Qxg6!+–) 33.Nxe2 Rxf7 34.Nf4+–, gives White an obvious advantage. 28.Qg5 Nd7

904

Compulsory. 28...Nh5? 29.Rxh5! gxh5 30.Qf6+ Kxh7 31.Qxf7+ Kh6 32.Kh1!, leaves Black in a desperate state. 29.Kh1?! White might have accepted a draw by repetition (29.Qh6 Nf6). His desire for victory entails serious dangers. 29...Qd8! 30.Qh6 Qf6 The black queen has been seriously improved. 31.Kg1 Qg7 32.Qh4 e5! 33.Nf3

905

A very complicated position, typical of the ‘Grivas Sicilian Defense’, with no real time left for both sides. White’s attack has evaporated - his h7-pawn is Black’s best defender! 33...d5?! It is time to make a point, by taking the initiative and entering White’s camp with a rook: 33...Rc2!

34.Ng3 f6!³, when Black has everything under control and his 2nd rank rook will win material. 34.d4! An impressive idea, aiming to keep the position closed and the b7-bishop inactive. White replies to 906

Black’s central strike with one of his own, which in this case proves to be the stronger one. 34...Rc2? An extremely difficult position to handle in severe time trouble and Black loses his bearings after the shock he has suffered. Correct was 34...dxe4! (34...exf4 35.e5!±; 34...exd4 35.e5 d3 (35...f6 36.Nexd4 fxe5 37.fxe5 Nxe5 38.Ng5+–) 36.Ned4±)

35.Nxe5 Nxe5 36.fxe5 Rc2°. 35.fxe5! Proceeding spectacularly and at the same time forcibly, as any move by the e2-knight would give Black the advantage. 35...Rxe2 There seems to be nothing better. 36.Ng5!

907

White invested a piece in his attack, which is rather strong, and Black can hardly do anything to extinguish it. 36...f6 Black should have tried 36...Re7, where White will eventually win, but time pressure would have increased the probability of error: 37.Rhf3 Rxe4 38.Nxe4 dxe4 39.Qxe7 exf3 40.Qxd7 Qh6 41.Qe8+ Kxh7 42.Qxf7+ Kh8 43.Qe8+ Kh7 44.Qe7+ Kg8 45.Qd8+ Kf7 (45...Kg7 46.Qc7+ Kh8 47.Qb8+) 46.e6+!+–. 37.exf6 Nxf6 38.e5! Game over! 38...Nh5 39.Rf7 Qh6 40.Rxb7 Rf8

908

41.Nf7+! The last, accurate blow and not 41.Rb8? Qxg5+! 42.Qxg5 Re1+, with a draw! 1–0 Kalesis Nikolaos : Grivas Efstratios B33 Iraklion 1992 1.e4 c5 2.Nf3 Nc6 3.d4 cxd4 4.Nxd4 Qb6 5.Nb3 Nf6 6.Nc3 e6 7.Qe2 Bb4 8.Bd2 0-0 9.a3 Be7 10.g4 d5 11.g5 Nxe4 12.Nxe4 dxe4 13.Qxe4 e5 14.Bd3 g6 15.Be3 Qc7 16.Qg2 Be6

909

Black is doing fine, as White’s early aggressiveness did not produce anything. 17.h4 A logical follow up as 17.Nd2 Nd4 18.Bxd4 exd4 19.0-0-0 Qa5µ, is not promising. 17...Rfd8 18.Nd2 A better try seems to be 18.Be4 Rac8 19.h5 Nd4 20.Nxd4 exd4 21.Bd2 Bd6³. 18...Nd4!

910

19.Bxd4 19.c3? Nb3! 20.Nxb3 Rxd3, is a lost case. 19...Rxd4 20.f3 The g4-square needs protection: 20.h5?! Rg4 21.Qf3 Bxg5–+. 20...Rad8 21.h5

21...Rxd3 An interesting and practical exchange sacrifice whereby Black gets the bishop pair and the initiative in return. Good is 21...Bf5 22.hxg6 fxg6 23.Bxf5 Rxd2 24.Qh3 h5!µ, but it seems that even better is 21...gxh5! 22.Rxh5 Rxd3 23.cxd3 Rxd3 24.Qe2 (24.Ne4?! Qc4!–+) 24...Qd7 25.Nf1 Qd4 26.Qe4 Qxe4+ 27.fxe4 Bg4µ. 22.cxd3 Rxd3 23.hxg6 fxg6 Forced, as 23...hxg6?, loses to 24.Qh2. 24.0-0 Maybe White should have opted for 24.Qe2, but after 24...Qd8! (24...Qd7? 25.Ne4 Qd4 26.Rd1∞) 25.Ne4 Rb3!µ, Black is clearly on the top.

911

24...Qd7! 24...Qb6+?, is attractive, but White can fight after 25.Kh1 Qxb2 26.Ne4 Qxg2+ (26...Qd4 27.Rac1 Bd8³) 27.Kxg2 Bxa3µ 28.Nf6+°. 25.Rf2 Black is a healthy pawn up after 25.Ne4 Bh3 26.Qh2 Bxf1 27.Rxf1 Qd4+µ.

25...Bc5?! 912

Natural, but it looks like 25...Bd5!, is even better: 26.Rc1 Bd8µ. 26.Ne4 Bxf2+ 27.Qxf2 Qd4

Black is obliged to exchange queens: 27...Qd8 28.Qc5! Qd4+. 28.Nc5? White’s strong e4-knight can offer him fair chances for salvation in the endgame, but he should be accurate: 28.Qxd4 Rxd4 29.Kf2 (29.Rc1 Rc4³) 29...Bf5 30.Ke3 Bxe4 31.fxe4 Rd7³. 28...Rd1+! 29.Rxd1 Qxd1+ 30.Kg2 Bd5 Now Black dominates. 31.Qe3 Qd4!

913

32.Kf2? Blundering a pawn. Objectively better is 32.Qxd4 exd4 33.Kf2 Kf7, but Black will anyway prevail. 32...Qxb2+ 33.Kg3 Qd4! 34.Qxd4 exd4 35.Kf4 b6 36.Nd7 Bb7 37.Nf6+ Kf7 38.Nxh7 b5! 39.Nf6 a5 40.Nd7 b4 More accurate is 40...a4! 41.Ne5+ Ke6 42.Nd3 Kd5–+. 41.axb4

914

41...axb4? Black played rather automatically, missing his last win by 41...a4! 42.Ne5+ Ke6 43.Nc4 Ba6 44.Na3 Kd5–+. 42.Nc5 Bd5 43.Ke5! b3 44.Nd3 Bxf3 45.Kxd4

Bad news for Black here; the position is a draw according to the tablebases! 45...Be2 46.Nb2 Ke6 47.Kc3! Kf5 48.Kxb3 Kxg5 49.Kc2 Kf4 50.Kd2 Kf3 51.Na4! To achieve the draw the white knight has to return to the kingside. 51...g5 52.Nc3 Bc4 53.Nd1! Bb5 54.Ne3 Ba6 55.Nd1 Black cannot improve, as 55...g4 56.Ne3! g3 57.Nf5! g2 58.Nh4+=, is even thus the opponents agreed to a draw. 1/2-1/2 Anagnostopoulos Dimitrios : Grivas Efstratios B33 Athens 1995 1.e4 c5 2.Nf3 Nc6 3.d4 cxd4 4.Nxd4 Qb6 5.Nb3 Nf6 6.Nc3 e6 7.Bd3 d6 8.Be3 Qc7 9.f4 a6 10.Qe2 b5 11.0-0-0 Nd7 12.Kb1 Nb6

915

13.Qf2 An interesting and probably better idea than 13.Rhe1, or 13.g4 Be7 14.Rhe1 Na4∞, as in Velimirovic,D-Grivas,E Athens 1999. 13...Na4 The text looks natural, but Black should prepare it by 13...Rb8!, when the position should be unclear. 14.Nxa4! The opening of the b-file looks to be in Black’s favor while the gain of time and destruction of Black’s queenside pawn structure are ‘unimportant’. But the truth is a bit different. 14...bxa4 15.Nd2 Not bad, but White should have thought about 15.Nd4 Be7 16.Nxc6 Qxc6 17.Bd4², or even better 15.Bb6! Qb7 16.Na5 Nxa5 17.Bxa5 a3 18.b3 Be7 19.Bc3 0-0 20.Qg3 f6 21.Bc4². 15...Be7 16.Nc4 Rb8

916

17.g4? Simply a loss of time as White never gets the chance to make use of his kingside pawn advance. White could still claim the advantage by 17.e5! d5 18.Nd6+ Bxd6 19.exd6 Qb7 (19...Qxd6 20.Bc5 Qc7 21.Rhe1±) 20.c4±. 17...0-0 18.g5

18...d5!

917

A decisive central strike, directly connected with Black’s queenside proceedings. 19.exd5 exd5 20.Ne5? White could and should opt for his only way to preserve the balance by 20.Nb6! Qb7 21.b3 d4 22.Nxc8 dxe3 23.Nxe7+ Qxe7 24.Qg2 axb3 25.cxb3 Nb4 26.Qe4 Qxe4 27.Bxe4 Rfe8∞. 20...Qb7?! The text looks promising, but Black would be on the top after 20...Nxe5! 21.fxe5 Bg4!µ and not the naive 21...Qxe5? 22.Bd4 Qc7 23.Qh4+–. 21.b3 Nb4! With a multitude of threats. For example: 22.-- 22...Nxa2! 23.Kxa2 axb3+ 24.cxb3 Qxb3+ 25.Ka1 Qa3+ 26.Qa2 Qc3+ and mate follows.

22.Bd4 Or 22.Ba7 Ra8 23.Bd4 axb3 24.cxb3 a5µ. 22...Nxd3 23.Rxd3? This simply loses. White has to be stubborn with 23.Nxd3 Bf5 24.Bb2, although his position would be far from attractive after 24...axb3 25.axb3 Rfc8 26.h4 a5µ. 23...Bf5!

918

Black is winning as the attack led by his active pieces (the f5-bishop in particular has no opponent) is unstoppable. Even the doubled a-pawns help, as they can deliver consecutive blows upon the spearhead of White’s queenside, the b3-pawn. 24.Rc3 Rfc8! Game over... 25.Rd3 Pure desperation. In any case, 25.Rxc8+ Rxc8 26.Rc1 axb3 27.axb3 Qxb3+!, would lead to the same result. 25...a5!

919

Opening lines is more urgent than capturing the hapless white rook which really cannot move anyways. 26.Ka1 Bxd3 27.Nxd3 axb3 28.cxb3 a4! Lines must be opened! 29.bxa4 Qa6! 30.Nb2 Ba3 31.Qe3 Bxb2+ 32.Bxb2

32...Rc2!

920

Black avoids the careless 32...Qxa4?! 33.Qe5 Rxb2 34.Qxb2 Qxf4, when he would still be winning, but would have to work much harder to conclude the game. 33.Re1 Qxa4!

0–1 Bellia Fabrizio : Grivas Efstratios B33 Vinkovci 1989 1.e4 c5 2.Nf3 Nc6 3.d4 cxd4 4.Nxd4 Qb6 5.Nb3 Nf6 6.Nc3 e6 7.Bd3 Be7 8.Be3 Qc7 9.f4 d6 10.Qf3 a6 11.0-0 0-0 12.g4 b5 13.g5 Nd7 14.Qh5 Nb4 15.Rf3 g6 16.Qh6 f5 17.gxf6 Rxf6 18.Rg3 Nf8 19.Nd4 Nxd3 20.cxd3

921

Black has repulsed White’s aggression while also preparing for the future by obtaining the bishop pair. 20...Bd7?! Careless. 20...b4 21.Nce2 Rf7∞, would be correct and fine. 21.a3?! Here White missed an interesting chance with 21.f5!? b4! 22.fxe6 bxc3 23.Nf5! (23.exd7? cxb2µ) 23...Rxf5 24.exf5 cxb2 25.Rf1 Bf6 26.fxg6 Nxg6

922

27.Rxg6+ (27.exd7?! Qxd7³) 27...hxg6 28.Qxg6+ Bg7 29.Qf7+ Kh8 30.exd7 Rd8=. 21...Rf7 22.Rc1 Qd8 The engines fail to understand the position and the potential of Black’s strategy. 23.Nce2?! White should have chosen 23.Nf3!, intending 24.d4, instead. 23...Bf6! 24.Rg2 Bg7 25.Qg5

25...e5! The bishop pair needs clarification of the center! 26.Nc6 Black obtains complete control over the position after 26.Qxd8?! Rxd8 27.Nc6 Rc8! (27...Bxc6 28.Rxc6 d5³) 28.Nb4 Rxc1+ 29.Bxc1 exf4µ. 26...Qe8! 27.Nb4 Ne6 28.Qg3 exf4 29.Nxf4 Be5 30.Nbd5 Rc8! 31.Rf1 And here 31.Rxc8? Qxc8 32.Nb6 Qc6 33.Nxd7 Qxd7 34.Rf2 g5!, is just winning for Black. 31...Bc6

923

White has fallen into various pins as the bishop pair is gaining in strength. 32.Qe1?! White should have played 32.Qh3 Nxf4 33.Nxf4 Qd7³. 32...Nxf4 33.Nxf4 Qe7! The position slowly clarifies in Black’s favour. His bishop pair keeps all of White’s possible plans in check. 34.Nh5 Rxf1+ 35.Qxf1 Rf8 36.Qe2

924

36...Bd7! With various threats, such as ...Bh3! 37.d4?! White’s final mistake, fatally weakening the e4-pawn. He had to sit tight with 37.Ng3. 37...Bh8 38.Ng3 Bg7 39.Rf2 Rc8 39...Rxf2 40.Qxf2 h5µ, would be great for Black as well. 40.Qd3

925

40...Qe6! 41.Ne2?! Although ultimately insufficient to change the result of the game, 41.Rc2, would have put up greater resistance: 41...Rxc2 42.Qxc2 h5!µ. 41...Re8! 41...Qc4!?, was also adequate: 42.Qxc4+ Rxc4 43.Bf4 Bh3!µ. 42.Ng3

926

White has no further defense. For example 42.Nc3 a5 43.b4 (43.Nxb5 Qxe4–+) 43...axb4 44.axb4 Rc8! 45.Nxb5 Bxb5 46.Qxb5 Qxe4–+. 42...Bc6! White resigned in view of 43.Rf4 (43.d5 Bxd5–+) 43...g5 44.Rf5 Bxe4 45.Qxe4 Qxe4 46.Nxe4 Rxe4 47.Bxg5 (47.Kf2 Bxd4 48.Bxd4 Rxd4 49.Rxg5+ Kf7–+) 47...Bxd4+–+. 0–1

Kotronias Vasilios : Grivas Efstratios B33 Zouberi 1993 1.e4 c5 2.Nf3 Nc6 3.d4 cxd4 4.Nxd4 Qb6 5.Nb3 Nf6 6.Nc3 e6 7.Bd3 d6 8.Be3 Qc7 9.f4 a6 10.Qf3 Be7 11.0-0-0 b5 12.Kb1 Nd7 13.g4 Nb4 14.g5 Bb7 15.Rhf1 0-0

16.h4 White usually prefers 16.Qh3, transposing to 15.Qh3, but not 16.Qh5 Rac8 17.Rf3? Nxd3 18.cxd3 (18.Rh3? Bxe4–+ (18...h6 19.Rxd3 Bxe4µ Wallace,J-Bellon Lopez,J Osterskars 1995)) 18...b4µ. 16...Rac8 Threatening 17...Nxc2! and 18...b4. 17.g6? Despite the fact that this standard move helps to open lines against the black king, in this position it is a bad idea as it allows Black considerable activity. White should have opted for the passive 17.Rc1 Nxd3 18.cxd3 Qb8∞. 17...Bf6!

928

Black doesn’t wish to lose any time and simply improves his pieces, but it was possible to accept the pawn sac by 17...fxg6 18.Qh3 Rf6 19.Bd4 e5 20.fxe5 Nxe5³, or by 17...hxg6 18.h5! g5∞. 18.gxf7+ After 18.gxh7+ Kh8!, the black king is shielded by the white h7-pawn, but it was still the best try. 18...Rxf7

19.Bd4

929

White’s position already looks bad after 19.Nd4?! Nxd3 20.cxd3 Bxd4 21.Bxd4 e5 22.Be3 b4 (22...exf4 23.Bxf4 b4 24.Ne2 Ne5³) 23.Ne2 d5!µ. 19...e5 20.fxe5 Nxe5 21.Qh3 Nbxd3! Black weakens White’s pawn structure and takes over the initiative. 22.cxd3 b4

23.Na4 The main alternative is 23.Nd5 Bxd5 24.exd5 Qc2+ 25.Ka1 Re8³. 23...Bc6 24.Nb6 24.Rc1?! Qd7! 25.Qxd7 Bxd7 26.Rxc8+ Bxc8 27.Nb6 Be6µ, leads to an endgame that is great for Black. 24...Rb8 25.Nd5 Bxd5 26.exd5

930

26...Qd7! Black would welcome the transition to an endgame as the superiority of his pawn structure would become a decisive factor. 27.Qg3?! White therefore feels obliged to seek tactical counterplay for which all of his pieces are necessary, but he should have try to defend in the endgame after 27.Qe6 Re8 28.Qxd7 Nxd7 29.Rf4³. 27...Qb5 28.Qg2 Rbf8 29.h5 h6! The white h-pawn should be stopped on h5, securing protection of f6 for Black. 30.Be3

931

Toying with threats such as 31.Bxh6, or 31.Nd4, followed by Nf5. 30...Nxd3! 31.Rxf6?! Desperation, but other options were also clearly hopeless: 31.Bxh6?! Nxb2 32.Rxf6 Nxd1 33.Rg6 Qd3+–+, or 31.Nd4 Bxd4 32.Bxd4 Qc4! 33.Rxf7 Rxf7 34.Qe4 (34.Qg1 Ne5 35.Bxe5 Qe4+–+) 34...Ne5 35.b3 Qb5 36.Bxe5 Re7 37.Rc1 Qd7 38.Qxb4 Rxe5µ. 31...Rxf6 32.Nd4 Qc4 33.Ne6 R8f7 34.Bd4

White could not have saved himself with 34.b3 Qc3! 35.Bd4 Rf2!–+, either. 932

34...Nf4! 35.Qh1 Nxe6! The simplest. By returning part of his extra material Black ensures simplification down to a clearly winning ending thus avoiding any complications that White could hope to benefit from. 36.Bxf6 Rxf6 37.dxe6 Rxe6

The resulting endgame with two extra pawns has been the logical outcome of Black’s strategic and tactical handling of the position. 38.Rc1 Qe4+ 39.Qxe4 Rxe4 40.Rc8+ Or 40.Rc6 a5 41.Rxd6 Re5! and the win is straightforward. 40...Kf7 41.Ra8 Re5 42.Rxa6 Rxh5 43.Rxd6 g5 44.Kc2 g4 45.Kd3 g3 46.Ke2 Rf5!

933

Cutting-off the white king! 47.Rd3 Rf2+ 48.Ke1 Rxb2 49.Rf3+ Ke7 50.Rxg3 Rxa2

Now the win is trivial; Black will give one of his two extra pawns, queening the other. 51.Rb3 Ra4 52.Kd2 h5 53.Kc2 Kf6 54.Kb2 Kg5 55.Rg3+ Kf4 56.Rd3 Ra5! 57.Rd4+ Kg5 58.Rxb4 Rc5 Again the white king is cut-off! 59.Rd4 h4 60.Rd3 Kh5 61.Kb1 Kg4 62.Rd4+ Kg3 934

Here the game was adjourned and White resigned due to the continuation 63.Rd3+ Kg2 64.Rd2+ Kf3 65.Rd3+ Ke2 66.Rh3 Rh5 67.Kc2 Kf2 68.Kd2 Kg2 69.Re3 h3–+.

935

The safest spot for the black king, supporting and being surrounded by a mass of pawns. 11.0-0 a6 12.Qg3 A plan involving Nd2–c4 seems preferable. 12...Bd6! 13.Qh4 After 13.Qg7 Qd8! and ...Qg8, White will have to suffer in an inferior ending. 13...Ne5! 14.Kh1 Ng6 15.Qh5 Nf4 Now in order to achieve the f4 advance White will first have to play g3, weakening the long h1-a8 diagonal which the c8-bishop will shortly occupy. In general, White faces serious problems to come up with a decent plan. 16.Qf3

936

16...h5! 17.Rae1 Be5 Black’s superiority increases with every move. White now resolves to free his position by exchanges. 18.Ne2 Nxe2 18...Ng6, is an interesting alternative. 19.Qxe2 Qc7! 20.Qe3 Bf4 21.Qh3 b5 Completing his development. 22.Nd4 Bb7 23.Ne2 Bd6

937

Now White has to seriously consider his next few moves as he appears to lack a plan. It is not easy to decide as it seems that something has gone wrong for him or maybe it was just the ‘Grivas Sicilian’? 24.a4 Playing f4 would weaken rather than activate White’s position. But this change of direction (from the kingside to the queenside) is further evidence that White is lacking a plan. With time-pressure approaching, White decides to complicate the position by any means instead of awaiting fate. This approach can only be commended from a practical viewpoint. 24...bxa4! 25.Ra1 a3! 26.bxa3 Bc5 27.a4

938

27...Bc6?! Black plays it safe, but quite strong is 27...h4 28.c3 d5µ. 28.c3 Qa7 29.Nf4!

29...h4! 29...Bxf2?, would open lines towards the black king and, more specifically it would lead to severe problems after 30.Qf3! Bh4 31.Nd5+ Bxd5 32.exd5 Bg5 33.Bc4°. 939

30.Rae1?! No need to abandon the a-pawn; he had to opt for 30.a5 Qc7 31.Ne2 d5³. 30...Bxa4 31.e5 fxe5?! 31...f5!µ, is stronger, when White would have no serious compensation for the sacrificed pawn. 32.Rxe5 Bd6?

A blunder in time trouble. Black had to go for 32...Bc6³. 33.Ra5? White returned the favour, missing his chance by 33.Rh5! Rxh5 34.Nxh5 Qc5 35.Qxh4+ Kf8 36.Nf6 Bc6 37.Nxd7+! Bxd7 38.Qh8+ Ke7 39.Qxa8 a5 40.Qh8±. 33...Bxf4?! Stronger is 33...Bc6 34.Rxa6 (34.Rh5 Rxh5 35.Nxh5 Kd8! 36.Qxh4+ Kc7µ) 34...Qc5 35.Rxa8 Bxa8µ. 34.Rxa4 Qc7 35.Rxa6 Rxa6 36.Bxa6 Be5 37.c4 Bf6

940

38.Bb5 Rb8 39.Qa3+ d6 40.Qe3 Ra8 Time trouble has passed, and Black retains a plus. However, the presence of opposite-colored bishops makes the conversion of this plus to a full point rather problematic. 41.Qe4 Ra2 42.h3? White had to play 42.g3!³. The black h-pawn will prove fatal! 42...Qb6! 43.f4 Qd4!

941

By exchanging queens Black increases his advantage as he can now create a passed pawn while at the same time preventing the white king from actively participating. 44.Qxd4 White can hardly avoid the exchange. After 44.Qb7+ Kf8, Black is threatening 45.-- 45...Ra1 46.Rxa1 Qxa1+ 47.Kh2 Bd4!. 44...Bxd4 45.f5 Black was planning ...Bf2, ...f5 and ...e5–e4 - thus White’s reply. In any case Black now coasts along to victory without difficulty by correctly using just his e-pawn! 45...Rc2! 46.fxe6 fxe6 47.Re1 Bf2 48.Rf1 Bg3 49.Kg1 e5 50.Rd1 e4 51.Kf1 Rf2+ 52.Kg1 Rb2 53.Ba6 e3 54.c5 dxc5 55.Kf1 Rf2+ 56.Kg1 Ra2 0–1 Vouldis Angelos : Grivas Efstratios B33 Rhodes 1993 1.e4 c5 2.Nf3 Nc6 3.d4 cxd4 4.Nxd4 Qb6 5.Nb3 Nf6 6.Nc3 e6 7.Be3 Qc7 8.f4 Bb4 9.Bd3 Bxc3+! 10.bxc3 d6 11.0-0 e5 12.Kh1 h6

This is a bad continuation compared to 12...Ng4! and should be avoided. 13.Qe1!

942

The white queen will be transferred to the kingside, preparing an assault on the enemy king. 13...b6?! Black is trying to play ‘as usual’, but here this doesn’t work. 14.fxe5! dxe5 Even after the alternative 14...Nxe5, White holds a good initiative: 15.Nd4 Bd7 16.a4!. 15.Qg3 Kf8 16.Nd4! Another white piece joins the attack! 16...Nh5? This move loses in spectacular style. Black should have played 16...Ne7 17.Nb5 (17.Nf5? Nxf5 18.exf5 Qxc3³; 17.Nf3 Ng6 18.Nh4! Nxh4 19.Qxh4²) 17...Qb8 18.c4 Be6 19.Nc3±.

17.Qg6! exd4 18.cxd4 White sacrificed a piece for a fierce attack due to Black’s lack of development and poorly placed king. 18...Nf6

943

19.Rxf6! Having sacrificed a piece, White offers a further exchange, eventually getting through to the black king. 19...gxf6 20.Qxf6 Rg8 20...Kg8 21.Rf1! Qe7 22.Qxc6 Bb7 23.Qc4 Rc8 24.Qb3, intending d5 and Bd4, is also winning for White, but perhaps Black should have tried this instead of the text... 21.Bf4!

944

This move had escaped Black’s attention, but the black king surely won’t escape! 21...Qd7 22.Bd6+ Ke8 Or 22...Ne7 23.Bc4 Rg7 24.Bxf7!+–.

23.Bb5! Bb7 24.d5 White wins material back - Black is busted. 24...Rc8 945

24...Qd8

Loses to 25.dxc6! Qxf6 26.c7+ Bc6 27.Bxc6#. 25.Rd1! a6 26.dxc6 Bxc6

27.Rd5! Black resigned as his king falls. An impressive lethal attack by White. 1–0 946

Hector Jonny : Grivas Efstratios B32 Katerini 1992 1.e4 c5 2.Nf3 Nc6 3.d4 cxd4 4.Nxd4 Qb6 5.Nxc6 bxc6 6.Bd3 e5 7.0-0 Nf6 8.Nd2 Be7 9.Nc4 Qc7 10.f4 d6 11.fxe5 dxe5

In general Black should feel happy with the opening outcome as he has more or less solved his problems. 12.Qf3 Another way to go is by 12.Bd2 0-0 13.Ba5 Qb8 14.Bc3 Nd7 15.Qh5 f6∞ Garcia Trujillo,J-Duarte,L Buenos Aires 2009. 12...0-0 Not that good is 12...Be6?! 13.Qg3² Borosova,Z-Tsifanskaya,L Szombathely 2003. 13.Qg3 Re8! Covering both the Bh6 and Qxe5 threats. 14.Kh1 Nd7

947

15.Bd2 And here 15.Ne3, was a decent alternative: 15...Nc5 16.Bc4 Rf8 17.Nf5 Bxf5 18.Rxf5 (18.exf5 Ne4 19.Qe1 Nf6∞) 18...Nxe4 19.Qxe5 Qxe5 20.Rxe5 Nf2+ 21.Kg1 Bf6 22.Re1 Ng4∞. 15...f6 16.Bh6?!

White gets carried away by his aggressive style and produces this dubious move. Objectively, 16.b4!, with chances for both sides, ought to have been chosen instead. 16...Bf8 17.Ne3 Kh8! 18.Nf5 Nc5 948

Certainly not 18...gxh6? 19.Bc4+–. 19.Be3 Nxd3 20.cxd3

Once again Black has obtained the advantage of the bishop pair, while also having fully repulsed White’s initiative. With his next move he hopes to encourage White to create some targets by pushing his b-pawn. 20...Qb7! 21.Qf2 After 21.b3 a5!, Black gets a good initiative against the white queenside pawn structure. 21...Rd8 22.Rfd1?! White should have satisfied himself with 22.d4. He had probably missed that after 22...exd4 23.Bxd4 c5 (23...Be6!∞) 24.Bc3 Qxe4, he can play 25.Nxg7! Bxg7 26.Bxf6 Rg8 27.Bxg7+ Rxg7 28.Qf8+ Rg8 29.Qf6+=. 22...Be6 23.b3 a5! 24.d4 What else? If 24.Rab1, then 24...a4 25.b4 Qb5µ. 24...exd4 25.Bxd4?! The alternative 25.Nxd4, gives White more chances of survival after 25...Bg4 26.Nf3 Rxd1+ 27.Rxd1 a4³.

949

25...a4 26.bxa4 Rxa4 Black’s advantage has grown to imposing proportions as new targets such as the a2-pawn have appeared. As the threat of ...Qd7 is now looming, White has to act. But the problem is that every bishop move loses the a-pawn; the white queenside has been weakened by the black maneuvers started by 20...Qb7 and which are now about to pick up the harvest! A good plan is more or less the pinnacle of our royal game! 27.Bc3 If 27.Bc5, then 27...Rxd1+ 28.Rxd1 Rxa2 29.Qd4 (29.Qxa2 Bxa2 30.Bxf8 h5µ) 29...Bxc5 30.Qxc5 h6µ. 27...Rxd1+ 28.Rxd1 Rxa2

Black has extracted a material gain without losing any aspect of his superiority. What remains to be done is to evade possible tactical tricks that White will employ in his effort to save the game. 29.Qd4 c5 30.Qd8 Ra8 31.Qd3 Qc6 32.e5 c4 33.Qc2 Unfortunately for White, the tactics after 33.exf6? cxd3 34.fxg7+ Bxg7 35.Bxg7+ Kg8 36.Ne7+ Kxg7 37.Nxc6 Bb3!, or 37...Bg4, clearly favour Black! 33...fxe5 34.Bxe5 Qc5

950

35.Qe4 Here 35.Bxg7+?, would also fail: 35...Bxg7 36.Nxg7 Kxg7 37.Qc3+ Kg6!–+. 35...Re8?! A time trouble clearly inferior move to 35...Ra5! 36.Re1 Qd5 37.Qf4 Qd7µ. 36.Nd4? White missed his last chance by 36.Nd6!

951

36...Bxd6 37.Rxd6! (37.Bxd6 Qh5µ) 37...Qf2 38.Rd1 Bf7 39.Qd4! Qxd4 40.Bxd4³, with fair surviving chances due to the opposite-colored bishops. 36...Bf7 Now its all over. 37.Nf3 Bh5 38.Rf1

952

38...c3! 39.g4 Bg6 40.Qf4 c2 41.h4 Bd3 42.Re1 Rc8 43.Bb2 Qf2 44.Bc1 Bf1!

The bishop pair dominated the position and paralyzed White’s pieces. The subsequent material losses were a logical consequence of Black’s advantage. 0–1 Motylev Alexander : Polgar Judit B33 Kallithea 2002 1.e4 c5 2.Nf3 Nc6 3.d4 cxd4 4.Nxd4 Qb6 5.Nb3 Nf6 6.Nc3 e6 7.Qe2 Bb4 8.Bd2 0-0 9.a3 Be7 10.0-0-0 d5 11.exd5 Nxd5 12.Nxd5 exd5 13.Bc3 Be6

953

14.Qf3 A Sicilian with opposite side castling has appeared. White could have played 14.Nd4, which is more to the point 14...Rac8 15.Qg3 g6 16.h4 A natural attacking continuation. But things are not looking good for White anyway: 16.Nd4?! Bf6!³, or 16.Be2?! Rfd8 17.Nd4 Nxd4 18.Bxd4 Bc5 19.Qe5 Bxd4 20.Rxd4 Qb3! 21.Bd3 Qa2µ Huschenbeth,N-Antoniewski,R Austria 2012. 16...Rfd8 17.h5 White appears to have a strong attack, but in fact after the next move Black is the one who creates threats quicker.

954

17...d4! While this enhances the light-squared bishop there are tactical elements to consider here as well. J. Polgar is really setting up a very pleasing exchange sacrifice to take over the dark squares. 18.hxg6 hxg6 19.Nxd4 The alternative is 19.Bd2 Bxb3 20.Qh3 (20.cxb3 Na5+ 21.Kb1 Qxb3µ) 20...Bf6 21.cxb3

21...d3! (21...Na5+? 22.Kb1 Qxb3 23.Qh7+ Kf8 24.Bb4++–) 22.Bc3 Ne5–+, when White’s position looks critical anyway. 955

19...Nxd4 20.Rxd4

20...Rxc3! The point. It is not too hard to see, especially when the long diagonal combines with the open h-file that this is the absolute key piece in the position. Still, the way in which the necessary defensive aspects of this sacrifice combine with very potent attacking resources too is a delight to watch. Note that the text is forced: 20...Rxd4?! 21.Qe5! Bg5+! 22.Qxg5 Rxc3 23.bxc3 Qd8! (23...Rd5? 24.Qh6±) 24.Rh8+ Kxh8 25.Qe5+ Kg8 26.cxd4². 21.bxc3 White’s hand is forced, as bad is 21.Rxd8+? Qxd8 22.Qxc3 Bg5+–+, or 21.Qe5? Bf6! 22.Qxf6 Rxc2+! 23.Kxc2 Bb3+–+. 21...Rxd4 21...Bxa3+ 22.Kd2 Rxd4+, is also possible, but the text has a very unhurried feel about it which emphasises Black’s utter confidence that her dark square domination will carry the day. 22.cxd4 Qxd4

956

Black has the better prospects and from the practical point of view White has almost no chances to survive against Black’s strong attack. 23.c3 23.Qb8+? Bf8µ, leads to nowhere. 23...Qc5

Black preserves the tension, avoiding 23...Bxa3+ 24.Kc2 Qb6 25.Qe5! (for another pawn White trades queens, which keeps him out of danger) 25...Qxf2+ 26.Be2 Qf5+ 27.Qxf5 Bxf5+ 28.Bd3 and 957

the draw is the most likely result. 24.Kd2?! 24.Be2?, is bad due to 24...Qxa3+ 25.Kd2 Qb2+ 26.Ke1 Kg7!µ, but the only way for White is 24.Kd1! Bf6 25.Bd3 Qxc3 26.Qb8+ Bc8 27.Ke2 b6°. 24...Bg5+ Better looks to be 24...Bf6! 25.a4 Kg7³. 25.Kc2? Not much different is 25.Ke1 Kg7! 26.Be2 Bf6³, but White should follow the line mentioned above: 25.Kd1! Bf6 26.Bd3 Qxc3 27.Qb8+ Bc8 28.Ke2 b6°. 25...Kg7!

The patience that comes from such a qualitative superiority of force. Black didn’t feel as if she was material down here. Her pieces have an enduring superiority which belies the simple number crunching of relative material values. 26.Bd3 26.Be2?, is losing to 26...Qd5!–+. 26...Bf6 27.Rb1?!

958

Hastens the end. Not that good is 27.Be2?! Qxa3–+, as well, but White should put-up a more stubborn defense by 27.c4 b5 28.Qe3 Qxa3µ. 27...Qxc3+ 28.Kd1

Now Black ends the game with some fine bishop moves. 28...Bg5! 29.Ke2 Bg4+! 30.Kf1 Or 30.Qxg4 Qd2+ 31.Kf1 Qxd3+ 32.Kg1 Qxb1+–+. 30...Bf4! The triumph of the black bishop pair. White resigned due to 31.Qxf4 Qxd3+–+. 0–1 Svidler Peter : Polgar Judit B32 Khanty-Mansiysk 2011 1.e4 c5 2.Nf3 Nc6 3.d4 cxd4 4.Nxd4 Qb6 5.Nb3 Nf6 6.Bd3 e6 7.0-0 Be7 8.c4 d5 9.cxd5 exd5

959

10.Nc3 The main alternative is 10.Be3 Qc7 11.exd5 Nxd5 12.Bc5 Be6 13.Na3 (13.Bxe7 Qxe7! (13...Ncxe7 14.Nd4 Bd7 15.Na3 0-0 16.Re1 Qf4 17.Re4 Qf6= Wehmeier,S-Illner,A Germany 2008) 14.Qf3 00³) 13...0-0 14.Nb5 Qd7 (14...Qf4 15.Bxe7 Ndxe7∞ Dworakowska,J-Arakhamia Grant,K Leon 2001) 15.Rc1 Nf4 16.Bc4 Qxd1 17.Rfxd1 Rfd8=. 10...Be6?! A novelty. Simpler is 10...dxe4 11.Nxe4 0-0 12.Qe2

960

12...Nd4 (12...Rd8!? 13.Be3 Qc7 14.Nxf6+ Bxf6 15.Rfd1 Qe5=) 13.Nxd4 Qxd4 and Black is fine, as in Timoshenko,G-Epishin,V Tbilisi 1989. 11.exd5 Nxd5 12.Nxd5 Bxd5

13.Be3?! I think here White could gain the upper hand with 13.Re1 Qd8 14.Qg4! (14.Bg5 0-0=) 14...0-0 15.Bh6 Bf6 16.Rad1². 13...Qb4! White probably missed this strong and energetic move which allows Black to obtain even play. 14.Qc2

961

An invitation to a draw. If White wanted to continue he should go for 14.Re1 0-0-0 (14...0-0? 15.Qh5+–) 15.Bd2 Qh4∞ when a sharp battle is on the cards. 14...Bxg2! Accepted! 15.Kxg2 Qg4+ 16.Kh1 Qf3+ 17.Kg1 Qg4+ 1/2-1/2 Dominguez Perez Leinier : Polgar Judit B33 Khanty-Mansiysk 2011 1.e4 c5 2.Nf3 Nc6 3.d4 cxd4 4.Nxd4 Qb6 5.Nb3 Nf6 6.Nc3 e6 7.Bg5 a6 8.Qd2

962

8...Qc7 An early novelty. More common is 8...Be7 9.0-0-0 d6 10.f4 Qc7 Khusnutdinov,R-Korobov,A St Petersburg 2018, although the black queen nearly always returns to c7, freeing her b-pawn to advance. 9.0-0-0 b5 10.f3 White tries to secure his center. Inconsequential is 10.Kb1 d6. But not 10...b4?! 11.Nd5!±. 10...Be7 11.Kb1 0-0 12.g4 Ne5 13.Bf4 What’s the point of playing an early Bg5, if not taking on f6 and later go for Bf4? I feel that White’s strategy is unimpressive, as Black’s position already looks quite good with an interesting battle ahead.

963

13...b4 14.Ne2 Rd8 Black is preparing the...d5 advance and there is little White can do about it. 15.Ned4 Bb7 16.Qe1?!

Too passive. White should focus on defense with 16.Be2 Rac8 17.Rhe1, although after 17...d5, Black’s position seems more pleasant. 16...Rac8

964

16...d5, was good as well: 17.exd5 Rxd5³. 17.h4 17.Bxe5 Qxe5 18.Qg3 d6, would be a slow death in the endgame due to the black bishop pair and the more flexible pawn structure.

17...d5! 18.exd5?! 18.g5, was White’s best chance. After 18...Nh5 19.Bh2 dxe4 20.fxe4 g6, Black’s position is fine but White can fight as well. 18...Rxd5 19.h5? A blunder. White should protect his vulnerable squares by 19.Rh3 Bd6 20.Rc1 Ng6µ.

965

19...Nxf3! An easy but effective combination that wins the game. 20.Qg3 20.Nxf3 Qxc2+ 21.Ka1 Rxd1+, mates, while; 20.Bxc7 Nxe1 21.Rxe1 (21.Bh2 Nxc2–+) 21...Rxc7– +, would end the game soon as well. 20...e5! White’s position is falling apart... 21.Bg2 exf4 22.Qxf3 Rxd4! Winning material and the game. 23.Nxd4 23.Qxb7? Qxc2+ 24.Ka1 Qxd1+ 25.Rxd1 Rxd1+ 26.Nc1 Rcxc1#. 23...Bxf3 24.Bxf3 Nd7 25.Rhe1 Bf6 26.Nc6 Ne5

966

White should have already resigned but the tension was too high and nobody could blame him. The end is near anyway. 27.Nxe5 Qxc2+ 28.Ka1 Bxe5 29.Rb1 f6 30.Be4 Qd2 31.Bf5 Bxb2+! 0–1 Dominguez Perez Leinier : Polgar Judit B33 Khanty-Mansiysk 2011 1.e4 c5 2.Nf3 Nc6 3.d4 cxd4 4.Nxd4 Qb6 5.Nb3 Nf6 6.Nc3 e6 7.Bg5 a6 8.Qf3 Be7 9.Qg3 d6 10.0-0-0 0-0

967

11.Kb1 The ‘real’ novelty of the game! It is always useful to tuck in the king after opposite castling in the Sicilian Defense. The tempo is not seen as lost because the king overprotects the a2-pawn and steps away from possible tactics on the c1-h6 diagonal. 11...Rd8

12.f4

968

The position resembles the ‘Richter-Rauzer’ Sicilian where White plays an early Nb3. The main difference is that the white queen is on g3 instead of d2, where she is certainly more aggressive on this square. 12...Qc7 The lost tempo that was mentioned earlier, releasing the b7-pawn. The black queen is awkward on b6 and J. Polgar decides to improve this piece. The queen not only prevents e5 for the time being but also clears the way for the black b-pawn, which is always an important trump in the quest for counterplay. 13.Bd3 b5 14.Qh4!? 14.Bh6 g6 (14...Bf8 15.Bg5 Be7=) 15.h4, was interesting and I think that White should have tried it. 14...h6!

15.Bxh6 gxh6 15...Nxe4 16.Qh3! (16.Bg5 Bxg5 17.fxg5 Nxc3+ 18.bxc3 g6³) 16...Nxc3+ 17.bxc3 g6 18.Qg3, with the idea of h4 is unclear. While 15...b4 16.Bxg7 Kxg7 17.Qg5+ Kf8 18.Qh6+ Ke8 19.Nd5! exd5 20.Qh8+ Kd7 21.Qh3+, ends in a draw by perpetual check. 16.Qxh6 Ne8? 16...b4, was objectively better but Judith Polgar is in a must-win situation and can’t afford the 969

perpetual (see the previous note), so she is trying to use the knight to cover the checks. 17.e5? 17.Nd5!, seems to be very strong, the point is that the queen is attacked and the capture on d5 opens the diagonal and the e-file: 17...exd5 18.exd5±. 17...f5! The problem for L. Dominguez is that he is down to 10 minutes for the remaining 23 moves. This can be a cause of concern if he doesn’t find a perpetual. 18.Bxf5 18.Qg6+!? Ng7 19.h4, was also unclear. 18...exf5 19.Nd5

19...Bf8 Black again is ‘forced’ to avoid 19...Qa7, due to 20.Rd3 (20.Qg6+ Ng7 21.exd6 Be6 22.Nxe7+ Nxe7 23.dxe7 Qxe7∞) 20...Bf8 21.Rg3+ Bg7 22.Nf6+ Kf8 23.Nh7+, with a draw. 20.Nxc7 Bxh6 21.Nxa8 Bxf4 22.exd6 Bxd6

970

White headed for an endgame where he will have a rook and two pawns for Black’s two minor pieces. No perpetual check but Black can’t hope to convert this into a victory without an error from White. This probability exists until White reaches the time control. 23.Nb6 Be6 24.Nd5 Kf7 25.Ne3 Nf6 26.g3 Ng4 27.Nxg4 fxg4 28.Nd4 Nxd4 29.Rxd4 With so little material left on the board, there is no clear way to make progress for black without a mistake by L. Dominguez. 29...Bc7 30.Rf1+ Ke7

971

31.Re4?! I do not see a way for Black to try for something more after 31.Rxd8 Bxd8 32.b3, as then Black couldn’t attack White’s pawns. White wrongly keeps both of his rooks on the board. 31...Rg8 32.a4 Bd6 33.axb5 axb5 34.Rf5 b4 35.Rh5 Rg6

36.h3 L. Dominguez is reaching the time control but caution is still needed as Black holds a pair of bishops and there might be back-rank issues. There was no need to give-up a pawn, although White should still be good enough to draw. 36...gxh3 37.Rxh3 Kd7 38.Rh7+ Kc6

972

39.b3? White should refrain from playing such a move before the time control. Now Black can hope to exploit the weakened dark squares around the king although it will not be easy. 39...Bd5 40.Re3 Bxg3 41.Ra7 Rg4 42.Ra4 Bf4 43.Re1 Bd2 44.Rd1 Bc3 Now the bishop pair dominates, and the c2-b3 weaknesses are about to be attacked - Black is improving her position. 45.Ra6+ Kb7 46.Ra5 Be4 47.Ra4 Rg2 48.Ra2 Kb6 49.Rd6+ Kb5 50.Rd1

973

50...Bf3 51.Rf1 Kc5 52.Ra7 Be4 53.Rc1 Kb6 54.Ra2 Rg3 55.Rf1 Bg7 56.Kc1 Rg2 57.Kb1 Rd2 58.Kc1 Rh2 59.Kb1 Bc3 60.Rd1 Bf3 61.Rf1 Kc5 62.Ra7 Be4 63.Rc1 Kd4 64.Rd7+ Ke3 65.Re7

It seems that White is holding but Black has found ideas to further improve her attack. 65...Rh6! With the threat...Ra6. 66.Ra7 Bd2?!

974

A nice winning continuation is by 66...Rd6 67.Ra4 Kd2 68.Ra2 Rh6 69.Ra7 Rc6 70.Ra8 Bf6 71.Ra7 Rc3 72.Rd7+ Ke2 73.Ka2 Bxc2–+. Black can win by a mating net or by a triple attack on the c2pawn 67.Rg1 Kf2 68.Rd1 Ke2 69.Rg1 Be3 70.Re7! Rh4 But not 70...Bxg1? 71.Rxe4+ Be3 72.Rxb4=. 71.Rg8 Bd4 72.Ka2 Kd2 73.Rd7

73...Bxc2 And Black finally is winning! 74.Rh8 74.Rb8, loses in a spectacular fashion by 74...Bb1+! 75.Kxb1 Rh1+ 76.Ka2 Ra1#. 74...Rxh8? 74...Kc1!, was curtains: 75.Rxh4 Bb1#. 75.Rxd4+ Bd3 76.Rxb4 Kc3

975

And according to tablebases this is mate in 21 moves! 77.Ra4 Rh2+? But not like that! 77...Rb8, was the correct track. 78.Ka3 Rb2 79.Rg4? From now on both sides made a lot of small ‘mistakes’ in this notorious ending and I do not feel it appropriate to comment on this, safely sitting behind my computer, armed with technology and pretend that I know everything. After all, chess is a battle on the board! 79.Ra7, was correct by the way! 79...Rxb3+ 80.Ka4 Rb1 81.Ka5 Rb5+ 82.Ka4 Rf5 83.Rg3 Rf4+ 84.Ka3 Rf1 85.Rg2 Rh1 86.Rb2 Ra1+ 87.Ra2 Rb1 88.Rg2 Rb3+ 89.Ka4 Rb4+ 90.Ka3 Rb6 91.Rg4 Ra6+ 92.Ra4 Rb6 93.Rg4 Rb7 94.Rh4 Rb1 95.Rh2 Rb6 96.Rh4 Bf1 97.Rg4 Rb5 98.Rg3+ Bd3 99.Rg4 Rb1 100.Rg2 Rb3+ 101.Ka4 Rb5 102.Rg4 Rf5 103.Ka3 Rf1 104.Rg2 Rb1 105.Rh2 Bf5 105...Bf1 106.Rf2 Bc4 107.Rf3+ Bd3 108.Rf2 Rb3+ 109.Ka2 Rb5 110.Ka1 Re5 111.Rb2 Bc2, is the trick, but it was not so simple for J.Polgar after five hours of play. 106.Rg2

976

106...Bd3? The ‘correct’ way, leading in mate in 10, but there is problem... 107.Rh2 Here White could claim a draw (before playing his move of course) by three times repetition (on moves 95, 105 and 107). But somehow he forgot it... 107...Bf1 108.Rf2 Bc4 109.Rf3+ Bd3 110.Rf2 Rb3+ 111.Ka2 Rb6 112.Ka1 Rg6 And White resigned as mate is near: 113.Rh2 Rg1+ 114.Ka2 Bc4+ 115.Ka3 Ra1+ 116.Ra2 Rxa2#. An amazing game! Going into the endgame, Dominguez believed he could find a fortress. But a deep calculation by J. Polgar and slight inaccuracies by White brought her the win. 0-1 Kotronias Vasilios : Haznedaroglu Kivanc B33 Athens 2007 1.e4 c5 2.Nf3 Nc6 3.d4 cxd4 4.Nxd4 Qb6 5.Nb3 Nf6 6.Nc3 e6 7.Bd3 Be7 8.Be3 Qc7 9.f4 d6 10.00 0-0 11.Qf3 a6 12.Kh1 Nb4 13.a3 Nxd3 14.cxd3 b5 15.Rac1 Qd7 16.Nd4 Bb7 17.Qh3 Rfc8

977

18.Rf3 The text move is the ‘real’ novelty. White wants to regroup his pieces on the kingside, following a similar idea which was played in Nunn,J-Grivas,E Athens 1991. Naive would be 18.Nf3?! a5 19.Ne2 b4 20.axb4 axb4 21.Bd4 Rxc1 22.Rxc1 Rc8³ Chocenko,DFrank,P Fuegen 2006. 18...Bf8 Black could also try the active 18...Rc5!? 19.g4 (19.Nb3?! Rh5 20.Qg3 a5³; 19.f5?! e5 20.Nde2 Rc7 (20...Rac8!? 21.Bxc5 dxc5°) 21.Rg3 Kh8 22.Ng1 d5 23.Nf3 Qd6∞) 19...a5 20.g5 Ne8 21.f5 b4∞. 19.Rg3

978

19...g6?! The weakening of the black king cannot be advisable. Black had to opt for 19...Kh8 20.Qh4 Qe7∞. 20.Rf1 Bg7 21.f5! Now White gets the initiative. 21...e5 22.Nf3 22.Nb3?! d5! 23.Nc5 (23.exd5 Bxd5 24.Nc5 Qc6 25.b4 Re8∞) 23...Qe7 24.Nxb7 d4!, looks fine for Black. 22...Nh5! 23.Rg5 23.Qxh5? gxh5 24.f6, is not working: 24...Qg4! 25.fxg7 Qd7 26.Nh4 Re8 27.Nf5 Re6 28.Rgf3 d5µ, but White should have opted for 23.Rg4! Nf6 24.Rh4 h5 25.Ng5². 23...Qe7 After 23...Nf6!, White has nothing better than a repetition with 24.Rg3 Nh5. 24.fxg6 fxg6

979

25.Rxh5!? An interesting exchange sacrifice, although Black should not be in danger. 25...gxh5 26.Nh4 Rf8 26...Kh8! 27.Nf5 Qe6 28.Qxh5 Rc7, is fine for Black, although White keeps a dynamic equilibrium. 27.Nf5 Rxf5? Returning the exchange is a bad sign. Black had to go for 27...Qf7! 28.Nh6+ Bxh6 29.Rxf7 Rxf7∞. 28.exf5 d5?

980

The decisive mistake but even after 28...h4 29.Ne4 Rf8 30.Bg5 Qd7 31.Bxh4, White is clearly better. 29.f6! Bxf6 30.Bc5! That’s what Black missed when he executed the...Rf8xf5 plan. 30...Qf7 30...Qxc5 31.Qe6+ Kh8 32.Qxf6+ Kg8 33.Rf5, is curtains. 31.d4! Re8 31...e4, loses to 32.Qg3+ Kh8 33.Bd6 Rg8 34.Qh4 Rg6 35.Rxf6 Rxf6 36.Be5 Kg7 37.Qg5++–. 32.dxe5 Rxe5 32...d4, doesn’t help: 33.exf6 (33.Qg3+ Kh8 34.Rxf6+–) 33...dxc3 34.Qxc3+–.

33.Bd4 Re6 33...Qe7 34.Qf3 Bg7 35.Bxe5 Bxe5 36.Nxd5+–. 34.Qg3+ Kf8 35.Rxf6 And Black resigned: 35...Rxf6 36.Bc5++–. 1–0 Carlsen Magnus : Gelfand Boris B33 Internet 2020 1.e4 c5 2.Nf3 Nc6 3.d4 cxd4 4.Nxd4 Qb6 5.Nb3 Nf6 6.Nc3 e6 7.Qe2 Bb4 8.Bd2 0-0 9.0-0-0 d5 10.e5

for Black here is the untested 12...a5 13.a4 f5! 14.Kb1 Nc5, which would be rather unclear. 13.Bd3 Nf8 14.Rhf1 Be7? Black is losing time and this is not a good sign. He should try 14...a5 15.a4 Bxc3 16.Bxc3 Nb4 17.Kb1².

15.Rf3! White is on top as his attack is quicker. 15...f5 15...a5?, is now losing to 16.Bxh7+! Nxh7 17.Rh3+–. 16.g4! g6 17.Qh3 d4 18.Ne2 a5 19.a4 Nb4

985

20.Bxb4! Qxb4 20...axb4, is an alternative try, but White still holds a considerable edge: 21.Bc4 fxg4 22.Qxg4 Qc7 23.Bb5±. 21.Bb5! And now the d4–pawn is doomed... 21...Bd7 22.Rxd4 Black will not hold long after the accurate 22.gxf5! Bxb5 23.axb5 exf5 24.Nbxd4±. 22...Bxb5?! 22...Qe1+ 23.Rd1 Qb4 24.Nbd4 fxg4 25.Qxg4 Bxb5 26.axb5 a4 27.Qh3±, is the only way for Black to hope for something better. 23.Rxb4 fxg4 24.Qxg4 Bxe2 25.Rd4! Bc5 26.Rxd8 Rxd8

986

27.Kb1! Stopping any mate on d1. 27...Rd1+ 28.Ka2 Rg1 29.Qh3 And Black resigned. After 29...Bxf3 30.Qxf3 b6 31.Nxc5 bxc5 32.Qf2, White will easily win. 1–0 Movsesian Sergei : Grivas Efstratios B33 Panormos 2001 1.e4 c5 2.Nf3 Nc6 3.d4 cxd4 4.Nxd4 Qb6 5.Nb3 Nf6 6.Nc3 e6 7.Qe2 Bb4 8.Bd2 0-0 9.a3 Be7 10.0-0-0 d5 11.Be3 Qc7 12.exd5 Nxd5 13.Nxd5 exd5 14.g4 Rd8 15.Bg2 Be6 16.Kb1 Rac8 17.f4 d4 18.Bc1 d3 19.Rxd3 Rxd3 20.Qxd3 Bxg4

987

Black has achieved a favorable exchange of his isolated pawn for White’s g-pawn. The opening of the g-file is of secondary importance as White can hardly make profitable use of it. 21.Be4 g6! 22.f5 This looks as natural as a baby’s smile, but it is actually the beginning of White’s problems. Indeed, White should have given top priority to improving his defenses. 22...Qd6! 22...Rd8 23.Qc4 Qd6∞, is another way to play.

988

23.Qc4 White could have opted for a slightly worse endgame with 23.Rg1 Qxd3 24.Bxd3 Bh5. However, it is not easy to make such tough but objective decisions in the heat of the battle with kings castled on opposite sides! 23...gxf5! 24.Rg1?! 24.Bd5 Rd8 25.Bxf7+ Kg7, is quite unclear. 24...Qxh2!

Another seemingly ‘illogical’ move and the second in a row by Black which opens more lines against his king. On the other hand, White cannot breach Black’s king shelter without pawns, while Black also strengthens his main defensive bastion, the g4-bishop (...h5 will follow). 25.Rh1 Perhaps 25.Rg2 Qh3!, had to be tried. 25...Qc7 26.Bd5 Ne5 27.Qf4 h5! Black has a winning position, as well as the usual enemy: severe time pressure. 28.Nd4 Bf6 29.Rg1 Bg7 30.Rg2

989

30...Ng6! 31.Qd2 Nothing is achieved by 31.Qg5 Qd8!µ. 31...a6?! 31...Rd8!, would have won easily. 32.Nf3 Ne7 33.Bb3 Rd8?! A second nearly consecutive mistake. 33...Bxf3! 34.Rxg7+ Kxg7 35.Qh6+ Kg8 36.Bg5 Nd5!, was winning, but not 36...Bd5? 37.Bf6!+–.

990

34.Qf2 Rd1 35.c3 Rd7?! Black could have tried to clear-up matters by 35...Rxc1+!

36.Kxc1 Qf4+ 37.Nd2 Qxf2 38.Rxf2 h4µ, but also quite good was 35...Rh1 36.Ng5 Rxc1+ 37.Kxc1 Bh6 38.Bxf7+ Kf8 39.Bxh5 Bxg5+ 40.Kc2 Bxh5 41.Rxg5 Bf7µ. 36.Ng5 Nd5!

991

37.Nxf7! Netherless White’s best practical chance. 37...Kxf7? It is only after this fourth (!) mistake by Black that White can finally succeed in (just) drawing the game, a clear indication of how hopeless White’s position was. Black had to try 37...Nxc3+

38.bxc3 Rxf7 39.Rg3 Kh7 40.Bxf7 Qxf7µ. 992

38.Rxg4!

38...hxg4 39.Qxf5+ Ke8 40.Bxd5 Qd6 41.Be6 Qd3+

It has become too risky for Black to keep the queens on the board but after the exchanges the ending is a theoretical draw: 42.Qxd3 Rxd3 43.Bxg4. 1/2-1/2

993

Chapter 3 - Endgame Technique The chess player, who wishes to master an opening should not only know how to gain an advantage from it or how to increase it in the middlegame, but also finally how to convert it in the endgame. Knowledge in typical endgames with specific pawn structures is important, as it helps to correctly evaluate our chances in them and to make middlegame decisions regarding the choice of possibilities that are very difficult to make otherwise. The endgames that follow are characteristic of the ‘Grivas Sicilian’. It is not important that some of them arise via another opening or system; the important thing is to understand and master them endgame technique is essential. Ermenkov Evgenij : Grivas Efstratios B33 Kallithea 2008 1.e4 c5 2.Nf3 Nc6 3.d4 cxd4 4.Nxd4 Qb6 5.Nb3 Nf6 6.Nc3 e6 7.Bd3 d6 8.0-0 a6 9.Be3 Qc7 10.f4 Be7 11.Qf3 0-0 12.a3 b5 13.Nd4 Nxd4 14.Bxd4 e5 15.Be3 Bb7 16.Rae1 Rad8 17.Kh1 exf4 18.Bxf4 Nd7 19.Nd5 Bxd5 20.exd5 Bf6 21.c3 Ne5 22.Bxe5 Bxe5

The position looks quite balanced and the presence of the opposite-colored bishops helps in this thought. But a more careful approach should reveal that the black bishop can become more active, thus Black has a better future! 23.a4! The only way for White to get some activity is to attack the black queenside.

994

23...bxa4! 23...Qc5?! 24.axb5 axb5 25.Re4 g6 (25...Qxd5 26.Rh4 Qxf3 27.Bxh7+ Kh8 28.Rxf3 Bf6 29.Rh5 Rb8 30.Rf4²) 26.Rb4, looks fine for White, as the b5 target gives him enough activity. 24.Ra1! And not 24.Bxa6? Qb6 25.Qe2 Rb8 26.Rf2 a3µ. 24...Rb8 25.Rf2 a5 26.Rxa4 g6

By playing the text move, which should normally be followed by ...f5, (a typical Sicilian Defense motif by the way), Black has limited the scope of the white bishop and he is ready to take action on the queenside; now White has to be rather careful. 27.g4?! Although White wants to stop the coming ...f5, there is no point in weakening the white king and especially the dark squares around him. Preferable is 27.Rc2 Rfe8 28.g3 Bg7³, but of course White’s position is passive and without any potential to create a threat. Passivity is a bad message in the Sicilian Defense! 27...Rb7 28.Kg2 Rfb8 29.Ra2 a4!

995

30.h3 And not 30.Rxa4? Rxb2 31.c4 Rxf2+ 32.Qxf2 Qd7–+. 30...Rb3 Not bad, but even stronger is 30...a3! 31.bxa3 Rb3 32.c4 Rc3 33.Rfc2 Rbb3 34.Rxc3 Rxc3 35.a4 Qc5 36.a5 Qd4 37.Rd2 Ra3µ. 31.Rc2 Qc5 Black has many choices here: 31...a3 32.bxa3 Rxc3 33.Rxc3 Qxc3µ. 32.Rf2 It is difficult to propose anything good for White. For example: 32.g5 a3 33.bxa3 Rxa3 34.Rxa3 Qxa3µ.

996

32...R8b7? Simply a blunder! After the simple 32...f6! 33.h4 Kg7µ, Black should prevail sooner or later as the threat of ...a3, shattering White’s queenside, is rather strong. 33.Ba6! Equal as well is 33.Bc2 R3b6 (33...Rxb2 34.Rxb2 Qxf2+ (34...Rxb2? 35.Qxf7+ Kh8 36.Qf8#) 35.Kxf2 Rxb2 36.Qd1 a3 37.Ke2 a2 38.Kd2 Rb1 39.Qxb1 axb1=Q 40.Bxb1=) 34.Bxa4 Ra6 35.Bb3 Raa7!°. 33...Ra7 34.Rxa4 White has won a pawn but even here he cannot claim any advantage. 34...f6 35.Rc4 Qa5 36.Rc8+ Kg7 37.Bc4 Rbb7 38.Rc6 Qa1!

997

39.b4? The text doesn’t help White, who should have opted for 39.Rxd6 Rxb2 40.Re6 Rxf2+ 41.Qxf2 Bxc3=, or for 39.Qe2 Ra8 40.Ra6! Rxa6 41.Bxa6 Rb8°. 39...Ra3! 40.Rf1 Or 40.Rc2 Bxc3 41.Bd3 Re7µ. 40...Qb2+ 41.Rf2

998

41...Qxc3? The text throws away Black’s advantage, which could be preserved by 41...Qc1! 42.Rf1 Qg5 43.Be2! (43.Ba6?! Rxb4 44.Rc7+ Kh6 45.Be2 (45.cxb4 Rxf3 46.Rxf3 Qd2+–+) 45...f5!–+; 43.Bd3 Bxc3 44.Rxd6 Be5 45.Ra6 Rxa6 46.Bxa6 Rxb4–+) 43...Rxb4 44.Rc7+ Kg8! (44...Kh6? 45.h4! Qf4 46.Qh3!+–) 45.Rc8+ Kf7 46.Rc7+ Kf8 47.Rc8+ Ke7 48.Rc7+ Kd8 49.Rxh7 Rb2µ. 42.Qxc3 Rxc3 43.b5! Ra7 After 43...Rg3+ 44.Kf1 Rxh3 45.b6 Rb8 46.Ba6, the white b-pawn gives White enough compensation to preserve the dynamic balance.

44.Rf3! The only way to preserve the balance! 44...Rc2+ 45.Rf2 Rc3 46.Rf3 Rc2+ Black has to accept the sharing of the point, as 46...Rxf3?, is bad due to 47.Kxf3 Ra3+ 48.Ke2 Rxh3 49.b6 Rh2+ 50.Ke3 Rb2 51.Rc7+ Kh6 52.b7 Kg5 53.Ba6+–. 1/2-1/2 Kotronias Vasilios : Grivas Efstratios B33 Iraklion 1992 1.e4 c5 2.Nf3 Nc6 3.d4 cxd4 4.Nxd4 Qb6 5.Nb3 Nf6 6.Nc3 e6 7.Bd3 d6 8.Be3 Qc7 9.f4 a6 999

White has a winning position as his extra material should be enough. 54...g5 The only way for Black to fight is to advance his g-pawn which is his only counterplay. 55.Kb5 g4 56.Rxe5 Easier is 56.Rf6 Be7 57.Rf7 Kd8 58.Bd5 g3 59.c6+–. 56...g3

1000

57.Rg5? White fails to a devilish trap! Good is here 57.Rf5 Be7 58.e5 Re1 59.Rf7 Rxe5 60.Rg7 Re3 61.Bf3!+–. 57...g2 58.e5

58...Bxc5! Black didn’t miss his chance! 1001

59.Rg7+ Kd8 60.Rxg2? Of course nothing is gained by 60.bxc5? Rb1+ 61.Kc4 g1=Q 62.Rxg1 Rxg1=, but White could still win by 60.Kxc5! Rc1+ 61.Kd6 g1=Q 62.Rxg1 Rxg1 63.e6 Rg7 64.b5 Rd7+ 65.Kc5 Re7 66.Bd7+–. This computer line cannot be found by a human so we can safely say that White made his mistakes earlier! 60...Rxg2 61.Bxg2 Bf8

In the diagramed position the white pawns are separated by two files and thus, in view of the above, White should be winning. However, the white king is unable to penetrate to a square from which he could capture the black bishop. 62.Ka5 Kc7 63.b5 Bc5 64.Ka6 Bd4 65.e6 Bc5 66.Bh3

1002

66...Kb8? A fatal mistake. Black could have held the draw by means of 66...Bd6! (66...Kd8, as well) 67.b6+ Kd8! (67...Kb8? 68.Kb5+–)

68.Kb7 Bc5! (68...Be5? 69.Ka8+–) 69.Kc6 Bf2 70.b7 Bg3 (70...Ba7=, as well) 71.Kb6 Bb8!, as the white king has no available path to the a8-square. 67.b6 Be7 68.Kb5! And Black resigned as the white king will win the black bishop by entering the d7-square. Well, 1003

Black was quite near to an undeserved draw! 1–0 Perdek Miroslaw : Grivas Efstratios B33 Kallithea 2007 1.e4 c5 2.Nf3 Nc6 3.d4 cxd4 4.Nxd4 Qb6 5.Nb3 Nf6 6.Nc3 e6 7.Bd3 d6 8.0-0 a6 9.a4 Qc7 10.a5 Be7 11.Be3 0-0 12.f4 Nb4 13.Qf3 Bd7 14.Bb6 Qb8 15.Rae1 e5 16.f5 Bc6 17.Nd2 Re8 18.Be3 Qc7 19.Nc4 d5 20.Bb6 Qb8 21.exd5 Nbxd5 22.Ne4 Nb4 23.Re2 Nxd3 24.cxd3 Qc8 25.Nxf6+ Bxf6 26.Qg3 Qd7 27.Nxe5 Bxe5 28.Rxe5 Rxe5 29.Qxe5 Qxd3 30.Bd4 f6 31.Qe3 Qc2 32.Qf2 Qc4 33.Re1 Re8 34.Rxe8+ Bxe8 35.Bc3 Bd7 36.Qd4 Qc6 37.g4 h6 38.Kf2 Be8 39.h4 Qh1 40.Kg3 Bc6 41.Qf2 Qe4 42.Bd4 Qd5 43.Bc3 Qd6+ 44.Kh3 Qd3+ 45.Kh2 Bf3 46.g5 hxg5 47.hxg5 fxg5 48.Bd2 g4 49.Bc3 Qxf5 50.Kg3 Qh7 51.Qd4 Qh3+ 52.Kf2 Qh2+ 53.Ke3 Qh6+ 54.Kf2 Qh4+ 55.Ke3 Qg5+ 56.Kf2 Bd5 57.Kg3 Be6 58.Bd2 Qh5 59.Bc3 Qh3+ 60.Kf4 Qh2+ 61.Ke3 Qh6+ 62.Kf2 Kf7 63.Kg3 Qh3+ 64.Kf2 Qh4+ 65.Ke3 Qh3+ 66.Kd2 Qh6+ 67.Ke2 Qg5 68.Qe4 g3 69.Qxb7+ Kg8 70.Qxg7+ Qxg7 71.Bxg7 Kxg7 72.Kf3 Kf6 73.Kxg3

A theoretically drawn position due to the wrong color of the queening square. Note that if White could get rid of his two pawns, then the draw would be an easy one! Well, of course Black should try his chances, as he has nothing to lose! 73...Ke5 74.Kf3 Kd4 75.Ke2 Kc4 76.b4 Bf5 77.Kd2 Be4 78.Ke3 Bg6 79.Kd2 Bf5 80.Kd1 Kc3 81.Ke1 Bg4 82.Kf2 Kd2 83.Kg3 Bd1 84.Kf4 Kd3 85.Ke5 Bf3 86.Kf4 Bh5 87.Ke5 Bf7 88.Kf4 Bg6 89.Kf3 Bf5 90.Kf4 Be4 91.Kg3 Ke3 92.Kg4 Bh1 93.Kg3 Bf3 94.Kh4 Be4 95.Kg3 Bf3 96.Kh4 Kf2 97.Kh3 Bh5 98.Kh4 Be2 99.Kh3 Kf3

1004

The only way for Black to prevail is to push his opponent into a zugzwang position, thus forcing the b5 advance thereby making his a-pawn a b-pawn after ...axb5. 100.Kh2? The wrong direction! With 100.Kh4!, White would save the draw, although he will have to find some more accurate moves, which actually hardens his task in a practical game. 100...Bf1! Black didn’t miss his chance! 101.Kg1 Bg2 And White resigned as he will find himself in a deadly zugzwang after 102.Kh2 Kf2 and he will have to opt for 103.b5 axb5 104.a6 b4 105.a7 b3 106.a8=Q Bxa8–+. 0–1 Alexakis Dimitrios : Grivas Efstratios B33 Athens 1992 1.e4 c5 2.Nf3 Nc6 3.d4 cxd4 4.Nxd4 Qb6 5.Nb3 Nf6 6.Nc3 e6 7.Bd3 Be7 8.Be3 Qc7 9.Qe2 d6 10.f4 a6 11.0-0 b5 12.a3 Bb7 13.Kh1 0-0 14.Rae1 b4 15.axb4 Nxb4 16.Bc1 e5 17.fxe5 dxe5 18.Rf3 Nxd3 19.cxd3 Rad8 20.Ref1 Bc8 21.Rg3 Kh8 22.Bg5 Be6 23.Nd2 Rfe8 24.Ra1 Nd7 25.Bxe7 Rxe7 26.Nc4 Nc5 27.Ne3 Nxd3 28.Ned5 Nf4 29.Qxa6 Bxd5 30.exd5 Red7 31.Rd1 h6 32.Rf3 Nxd5 33.Nxd5 Rxd5 34.Rdf1 Rd1 35.Qa4 Rxf1+ 36.Rxf1 Qb7 37.Qc2 Rd4 38.h3 g6 39.Qc5 Kg8

1005

40.Qxe5 Re4 41.Qc3 Re2 42.Qf3 Qxf3 43.Rxf3 Rxb2 44.Kh2

White can feel safe. All he has to do is patiently wait on his 1st rank or harass the enemy king with checks when the latter attempts to invade the white camp. 44...Kg7 45.Rd3 g5 46.Kg3 46.h4 f5 (46...g4 47.Rd5=) 47.hxg5 hxg5 48.Kh3, is easier. 46...Kg6 47.Kf3 h5 48.Kg3 h4+ 49.Kh2 49.Kf3, is natural, but the text is not losing. 49...Rb1

1006

White stands OK and obviously he can hold the draw... 50.g3? A fatal blunder allowing Black to obtain a passed pawn. White should have been patient and played 50.Ra3, getting ready to deliver side checks as soon as Black pushes his f- and g-pawns. 50...Rb2+! 51.Kg1 hxg3 52.Rxg3 f5 The passed f-pawn and the white king’s bad placement are decisive factors. 53.Rf3 Ra2 54.Kh1 Ra5! Aiming to liberate the black king. 54...f4?, is a tragic mistake in view of 55.h4! Kf5 56.hxg5 Kxg5=, with the Philidor Position! 55.Kg2 Kh5 56.Rc3 Kh4 57.Rc4+ f4 58.Rc3 58.Rc2 Ra3!, is not of a help. 58...Ra2+ White resigned in view of 59.Kg1 Re2! 60.Rb3 Re3

0–1 Dervishi Erald : Grivas Efstratios B32 Katerini 1993 1.e4 c5 2.Nf3 Nc6 3.d4 cxd4 4.Nxd4 Qb6 5.Nxc6 bxc6 6.Bd3 e5 7.c4 Nf6 8.0-0 Be7 9.Nc3 d6 10.b3 0-0 11.Be3 Qb7 12.Be2 Be6 13.Bf3 Rad8 14.Qe2 Rfe8 15.Rfd1 Nd7 16.Rd2 Nc5 17.Rad1 Qb4 18.Bxc5 Qxc5 19.Bg4 Qa5 20.Rd3 Qc7 21.h3 g6 22.Bxe6 fxe6

The doubled e-pawns help Black to control the center. The position is approximately equal as White 1008

has not created any weaknesses in his camp. A good plan for him would now be to develop a queenside initiative with 23.b4. Instead of this, he opts for play on the wrong flank. 23.Qg4 Bf8 24.h4?! Creating a future target without gaining anything significant in return. 24...Rd7! Intending to exploit the possible opening of files after White’s 25.h5, with 25...Rg7. 25.Qh3 Rf7

26.Rf3?! Exchanges hardly suit White, as the endgame is in Black’s favour. White fails to understand the position. 26...Rxf3 27.Qxf3 Qf7! 28.Qxf7+? White should not exchange queens. He should have opted for something like 28.Qe2, preserving the balance. 28...Kxf7

1009

In the ending that has come about Black is better thanks to his superior center, strong bishop (the weakness on h4!) and a multitude of pawn-breaks (...a5-a4, ...d5, ...h5 and ...g5). 29.Kf1 Be7 30.Ke2 Rd8 31.g3 Rd7 32.Rd3 Bd8! Intending to improve the potential of his minor piece with 33...Bb6 and ...Bd4, at the right time. 33.Na4 Ke7 34.h5?

This serious mistake hastens the end. White should have remained passive and refrained from making further concessions such as opening up the g-file. 1010

34...gxh5! 35.Rd1 Ke8 36.Rh1 h4! 37.gxh4 Rg7! A new positional factor has developed in Black’s favor – the open g-file. 38.Kf3 After 38.h5 Rg4!

39.Kf3 Rf4+ 40.Ke3 Bg5, Black’s victory would be close at hand. 38...h5!

1011

Fixing the weakness on h4. White cannot resist much longer as Black wins material. 39.Rd1 Ke7 40.Rh1 Rg4 41.Rh3 Kf7 42.Nb2 Rf4+! The weak white h4-pawn can wait as more important pawns come first. 43.Ke3 Bb6+ 44.Kd3 Rxf2 Game over. 45.Nd1 Rf4 46.Rh2 d5! 47.Re2 Bd4! 48.b4 Rxh4 49.b5 Rh3+ 50.Kc2 cxb5 51.cxd5 exd5 52.exd5 Ke7 53.Nf2?! Rh2 0–1 Pandavos Panayotis : Grivas Efstratios B33 Athens 2000 1.e4 c5 2.Nf3 Nc6 3.d4 cxd4 4.Nxd4 Qb6 5.Nb3 Nf6 6.Nc3 e6 7.Bd3 d6 8.0-0 a6 9.a3 Be7 10.Be3 Qc7 11.f4 b5 12.Qf3 0-0 13.Rae1 Rb8 14.Kh1 b4 15.Ne2 bxa3 16.bxa3 e5 17.f5 Na5 18.Nd2 Bb7 19.Rb1 Bc6 20.c4

Black has the better pawn structure (two pawn islands compared to his opponent’s three pawn islands), while White is lacking any aggressive plan. The transfer to an endgame seems to be a fair choice. 20...Rxb1!

1012

A very significant detail. Black seeks major piece exchanges so as to forestall any aggressive action by White while aiming at the favorable ending guaranteed by his healthier pawn structure. 21.Rxb1 Rb8 22.Rb4 Ba8! 23.h3 Nc6 24.Rxb8+ Qxb8 25.Qf1 White has no choice as he cannot allow the penetration of the black queen on the queenside. 25...Bd8!

The forgotten black bishop prepares to enter the fray via a5 or exchange itself with the e3-bishop. 26.Qb1 Otherwise 26...Bb6, would be strong, while 26.Qg1, is met by 26...Nd7!. 26...Qxb1+ 27.Bxb1 Nd7 28.Bd3 Bb7 And not 28...Bb6?! 29.Bxb6 Nxb6 30.c5! dxc5 31.Bxa6=. 29.Nb3 Na5! 30.Nec1 Kf8

1013

31.Nxa5 Simple and expected but rather passive, adding nothing to White’s resistance and general savings efforts. Maybe he should think of something more concrete like 31.c5 Nxb3 (31...Nf6 32.Nxa5 Bxa5 33.cxd6 Nxe4 34.Nb3 Bd8 35.Nc5 Nxc5 36.Bxc5 Ke8³) 32.Nxb3 d5! 33.exd5 Bxd5 34.Nd2 Be7³. 31...Bxa5 32.Nb3 Bd8 33.Kg1

33...a5!

1014

Seeking to gain further space while restricting the white knight and to fix the white pawn on a3. 34.a4?! This doesn’t help. White should have stayed put by 34.Kf2 and await developments. 34...Bc6! 35.Bd2 Bxa4 36.Nxa5 36.Bxa5?, loses material to 36...Bxb3 37.Bxd8 Nc5µ, but also strong is 36...Bxa5 37.Nxa5 Nc5 38.Bb1 Ke8 and the a5–knight will soon fall! 36...Nc5 37.Bb1 It seems that White has managed to defend. However, things are not exactly the way he would like as the exchange of pawns on the queenside allows Black to give up the two bishops since his knight will be the superior minor piece in view of the fact that pawns exist mostly on one wing. Moreover, Black also wins material, but this would not be significant enough if he did not have the knight.

37...Bxa5! 38.Bxa5 Bb3 39.Kf2 Bxc4 40.Ke3 Bf1 41.Kf2 Bd3! Securing a won ending thanks to the extra pawn and knight vs bishop aided by the presence of pawns on only one wing. 42.Bxd3 Nxd3+ 43.Ke3 Nc5 44.g4 Ke7 45.Bb4 Kd7 46.h4 Kc6 47.Ba5 d5!

1015

The exchange of pawns allows the black king to centralize while also transforming the e5-pawn into a passed one. 48.exd5+ Kxd5 49.Bc3 Ne4 50.Bb2 Nd6 51.Kf3 h5!

The last pawn break, shattering the white pawns. The end is near. 52.Ba3 e4+! 53.Kf4 hxg4 54.Kxg4 The pawn ending after 54.Bxd6 Kxd6 55.Kxe4 g3 56.Kf3 Ke5, is easily won for Black. 54...e3! 55.h5 1016

55.Kf3 Nxf5 56.h5 Nd4+–+. 55...f6 Avoiding a simple trap White had set (56.f6!), but good enough as well is 55...e2 56.Bb4 f6 57.Kf3 Kc4 58.Be1 Kd3–+. 56.Kf3 Nxf5 57.Bf8 White resigned realizing the futility of resistance after 57...Kd4. White’s last trap, 58.Bxg7 Nxg7 59.h6, does not work in view of 59...Ne6! 60.h7 Ng5+–+. 0–1 Krajina Davor : Grivas Efstratios B33 Vinkovci 1989 1.e4 c5 2.Nf3 Nc6 3.d4 cxd4 4.Nxd4 Qb6 5.Nb3 Nf6 6.Nc3 e6 7.Be3 Qc7 8.a3 a6 9.f4 d6 10.Bd3 Be7 11.Qf3 b5 12.0-0 0-0 13.Nd4 Nxd4 14.Bxd4 e5 15.Be3 Bb7 16.Rae1 Rac8 17.Kh1 Qd7 18.Nd5 Bxd5 19.exd5 Ng4 20.Bd2 f5 21.fxe5 Nxe5 22.Qh3 g6 23.Bc3 Bf6 24.Re2 Rc5 25.Rd2 Re8 26.Bb4 Nxd3 27.Qxd3 Rc4 28.Qg3 Be5 29.Qf3 Re4 30.Bc3 Rf4 31.Qd3 Rxf1+ 32.Qxf1 Bxc3 33.bxc3 Qe7 34.h3 Qe4 35.Qd3 Qf4 36.Rd1 Re3 37.Qd2 Qe4 38.Kg1 Re2 39.Qg5 Kg7 40.Kh1 h6 41.Qg3 f4 42.Qg4 h5 43.Qd7+ Kh6 44.Rg1 Qxd5 45.Qd8 Kg7 46.Qd7+ Qf7 47.Qxd6 f3 48.Qd3 fxg2+ 49.Rxg2 Re1+ 50.Rg1 Re6

Black has the better ending as he can claim that he is a pawn-up due to the doubled white c-pawns. In addition, his king is obviously safer compared to his counterpart. 1017

51.Rf1 Qe7 52.Qd4+ Kg8?! Black should welcome a queen ending especially a pawn-up after 52...Kh7 53.Qd5 Re1! 54.Rxe1 Qxe1+ 55.Kg2 Qxc3µ. 53.Qd5 Qd6? In the rook ending White’s hopes are considerably increased so Black shouldn’t go for it. Sufficient is 53...Kh7µ. 54.Qxd6! Rxd6

55.a4! Creating targets to attack. 55...bxa4 After 55...Rc6 56.axb5 axb5 57.Rf3, White will hold. 56.Ra1 Rc6 57.Rxa4 Kf7 57...Rxc3 58.Rxa6 Kg7 (58...Rxh3+ 59.Kg2 Rc3 60.Rxg6+ Kh7 61.Ra6 Rxc2+ 62.Kg3=) 59.Kg2! Rxc2+ 60.Kg3, is already a theoretical draw. 58.Kg2 Ke6 59.Ra3 Kd5 60.Kf3 Rf6+ Nothing is gained by 60...g5 61.Ra5+ Rc5 62.c4+ Kxc4 63.Rxa6=. 1018

61.Kg3 Ke4 62.Ra5 Ke3 63.Rd5! Stopping any black ideas like transferring his king to attack the doubled c-pawns. 63...Rc6 64.Kh4 Rxc3 65.Rd6 a5 66.Rxg6 Rc5

67.Rd6! Again keeping the black king into bay, not allowing him to attack the c-pawn. 67...Ke4 68.c4! Ke5 68...Rxc4 69.Kxh5=. 69.Rd8! Preserving the rook on the d-file while avoiding 69.Ra6? Kd4–+. 69...Ke6 70.Rd1 Ke7 70...a4 71.Ra1 Ra5 72.c5! and White holds. 71.Rd2 Ke6 72.Rd1 a4 73.Ra1 Ra5

1019

74.c5! Not the only way to draw, but the safest and clearest. 74...Rxc5 75.Rxa4 Kf7 1/2-1/2
