To improve and succeed, a chessplayer must be able calculate precisely and
visualize prospective positions. This is easier said than done. While
pondering the next move, a chessplayer frequently keeps “replaying” the
same melody in his mind, thus falling into a kind of trance.
This book by Russian grandmaster Konstantin Chernyshov is designed to
improve your visualization and calculation skills. With 500 exercises and
an additional 250 puzzles, the author provides a vast amount of material to
work through for students and coaches of the game. Most exercises require
the reader to go through several stages of thought, including visualizing
the configuration of the pieces, evaluating the resulting positions, and
finally, calculating an accurate continuation.
The regimen suggested by the author will require a disciplined approach by
serious chessplayers. The exercises and puzzles start out with easy
examples, but they gradually become more difficult. And all are meant to be
solved without sight of the board.
As noted by Ian Harris in his foreword:
“Cognitive Chess is designed to train you to visualize the board and
correctly calculate sequences in your mind, skills that are essential to
problem solving in all phases of the game. Players who train in these areas
will certainly see an overall improvement in their game. After all, chess
is ultimately a contest between opponents to determine who can
‘out-calculate’ the other.”
