Every player has heard the saying, "Chess is 99 percent tactics." It isn't. It's 99 percent calculation. But until now there has never been a book devoted entirely to this most mysterious and essential chess technique.
This book examines both the technical and practical aspects of how to think ahead -- the selection of candidate moves, the evaluation of end positions, finding the proper move order, and the like.
Special attention is paid to the broad range of calculating mistakes, such as overlooked zwischenzugs and "quiet moves," visualization blunders, and "believing" your opponent.
