Every chess player, from club level up, can improve their game by using engines. That is the message of Matthew Sadlers thought-provoking new book, based on many years of experience with the worlds best chess software. You may not be able to replicate their dazzling-deep calculations, but there is so much more your engine can do for you than just checking variations! Matthew Sadler, co-author of the ground-breaking bestseller Game Changer, presents some unique methods to improve by using your engine. He explains how in your opening preparation, instead of sifting through masses of computer analysis you should play training games against your engine. He also shows how to train your early middlegame play, the conversion of advantages, your positional play, and your defensive skills. And, of course: how to analyse your own games. These generic training methods Sadler supplements with concrete techniques. He explains how the top engines tackle crucial middlegame themes such as entrenched pieces, whole board play, attacking rhythm, exchanging pieces, the march of the Rooks pawn, queen versus pieces, and many others. He also opens your eyes to typical strategies that the engines found and fine-tuned in popular openings such as the Kings Indian, the Grunfeld, the Slav, the French and the Sicilian. Sadler illustrates his lessons with a collection of fantastic games, explained with his trademark enthusiasm. For the first time, the superhuman powers of the chess engine have been decoded to the benefit of all players, in a rich and highly instructive book.
