INTRODUCTION

Dear Reader! Before you is our third book on chess combinations. We should straight away � the reservation that, if you are unacquainted with Books 1 and 2, you will find it difficult :Ii your own to cope with the tests in this book. The arrangement and the tests in this book differ somewhat from those in Books 1 and 2. � tests are aimed primarily at players of master strength, or those approaching it. In Russia � corresponds to the grades of Candidate Master and Master of Sport (about 200+ on the BCF ;;..�-e. or 2200+ on the Elo scale). The system offered was tested for more than ten years with :-..: �·outh team of the Russian Republic, which in its time included the former World Champion .�oly Karpov, grandmasters Balashov. Rashkovsky. Sveshnikov, Timoshchenko and Tsesh­ �.. and many others who subsequently became well-known players. The essence of the system is as follows. The evaluation of each test is worked out on as-point �. The highest score of 5 is awarded for a correct solution, including all the most important .-.lations. If the solver indicates a subtlety not mentioned in the solution. his score may be -!'lo--reased by 1 point. Often the solver will find a second path. apart from the author's. one which :s also correct. In this case the score should again be 5 points. A score of 4 is awarded for a correct but incomplete solution. For example. an important defensive resource may have been :mined. If the start is indicated correctly. but the essential "point" is missed. a score of 3 is given. \\nen a correct start is made, but then a bad oversight is committed. a score of 2 is awarded. If �l�· the first move is given correctly. the solver receives 1 point If no solution is given, or if it is a completely incorrect one, no points are awarded. We have detennined a guiding time for each position. depending upon the degree of difficulty. The total time allotted to one test should be not less than two hours, but also not more than three. While in the previous books the time allotted to a test was considerably less. here. raking account of the complexity and serious nature of the examples. we consider the indicated rime to be the most reasonable. In solving the examples in this book. you should not. as in the previous books. put the accent on one definite theme. but should select for yourself 8-12 examples beforehand. alternating them irom the various themes. And here we should draw your attention to the fact that all answers should be written down. and should be checked with the correct solutions only after you have solved all the positions in the projected test. Basing yourself upon the time planned. choose positions by alternating difficult ones with less difficult ones. As in Books 1 and 2, you should award yourself bonus or penalty rime points, at the rate of one point per five minute difference from the suggested total time.

Your Chess IQ There are altogether 378 positions in this book. so that a 100% solution can earn you a total of 1890 points. With time bonuses it is possible. of course. to earn a score in excess of 100%. On the basis of the solutions to a small sample of positions submitted by a range of volunteers. "-e suggest the following "Chess IQ" table:
