Introduction

Spending as little as 10-15 minutes a day on one's tactical ability really can reap dividends. I can certainly testify to that myself and it's always very welcome to see a pupil regularly try­ ing to solve a number of tactical exercises: not only do they become more tactically alert, but they also improve their clock handling and gain in confidence. That's what I wrote at the start of The Complete Chess Workout in 2007 and it's some­ thing I most certainly still believe. Back then after months of studying the output of innu­ merable database searches to compile 1200 puzzles, I vowed never again to produce a tac­ tics book, but times change and the gentle, constant probing from friends and readers for a follow-up work caused me to go back into the laboratory as it were. Since the start of the year I've been noting down interesting positions every time I've followed a tournament or studied the latest games in an opening variation. That does not, however, produce anywhere near 1200 positions, even allowing too for drawing heavily on my own games, as well as those of pupil s and friends. Thus the summer has been largely dominated by not only running searches and then sifting through the results for all the key tactical motifs which the club player must be aware of, like i.xh7+, but also much lesser known combinational ideas, such as ...l::!.xes, which should improve readers' calculation skills while ideally helping them become more creative in their own games. Well into this project a highly interesting work, Greatest 365 Puzzles, by Csaba Balogh appeared, drawing solely on games from the first four months of 2012. I've certainly en­ joyed solving some of those, but in case any strong club players have purchased that work as well as this, I did remove several puzzles. The two works now have fewer than 20 posi­ tions in common; ones which were so rare, instructive or just plain beautiful that I could hardly leave them out. Likewise, knowing too that many English readers subscribe to CHESS and solve the many puzzles presented monthly in that magazine, I've again tried to keep the number of recent positions in common with that publication to well under two dozen. Nobody likes to solve a position from a very well-known game more than once, unless it's extremely challenging, but finding several, say, l::!.x g7+ sacrifices in this work should help to mean that you never miss that motif again in your own games. As with its predecessor, do please aware in this work that by no means every position sees one side attacking. Tactics lurk in even the quietest looking positions, especially when a piece is loose. Try, indeed, never to forget John Nunn's useful mnemonic LPDO ('loose

Th e C o m p l e te Ch ess Work o u t 2 pieces drop off') . Knowledge of that, as well as a recognition of all the available pawn breaks in a position, can really help most club players to make noticeable progress in my view. As such I've tried to include a few more positions this time where the humble pawn plays a pivotal role. Elsewhere, we have slightly fewer opening traps, but that is more than compensated by a small increase in the size of the Fiendish chapter; 60 positions which should tax even the very strong club player. I've again sorted each chapter by place, thereby ensuring that not all examples of a theme are grouped together and meaning that a straightforward combinational blow might be followed by a challenging, unusual idea. Finally, special thanks are due to all those who kindly submitted positions for inclusion, as well as to my colleagues, Byron Jacobs and John Emms, for their unstinting help and support.

Chapter One

Warming Up Even those fairly new to the game should find the following hundred puzzles quite solv­ able. Just remember that you're not always looking to force mate; quite often the solution is just a little tactic to pick up a pawn or the exchange. 1)
