There are many differing opinions amongst the top players in the world of chess, but there is one thing upon which World Champions, Grandmasters and other experts all agree: the art of chess calculation is the absolute key to the success of a player.

Master this discipline and you can surely expect your results to improve dramatically. And yet there have been very few serious attempts in the past by chess authors to delve into this delicate topic, perhaps not surprisingly given its complexity and difficulty.

In Excelling at Chess Calculation, Jacob Aagaard tackles the subject matter head on, unravelling the many secrets behind chess calculation and arming the reader with the necessary tools to be able to calculate effectively at the chessboard.

Aagaard pays particular attention to the searching practical questions like "when should you calculate?", "how can you discover candidate moves?" and "how long should you spend on critical moves?"

A thorough study of this book will enable you to calculate with confidence in future games.
