Have there been times during a game when you have calculated a position for half an hour, only to find out that most of what you were thinking about was of little use? If you have not, maybe the only way to improve your calculation is to upgrade your processor. But if you are human, then this book will offer you practical advice and an effective training plan to think differently and make decisions far more efficiently.

In Calculation thinking methods such as Candidates, Combinations, Prophylaxis, Comparison, Elimination, Intermediate Moves, Imagination and Traps are explained to the reader, and ownership of them is offered through a carefully selected series of exercises.

Reviews

"Studying Grandmaster Preparation: Calculation carefully will make you a much stronger player, open your eyes to new possibilities, allow you to immerse yourself into positions from completely different angles, and see possibilities that would have surprised you before. This book teaches your mind to think differently and solve complicated task; provided you have taken the time to work your way through this book. It is written for strong players and those who are serious about improving their chess understanding and their ability to calculate accurately. To benefit from this book you should probably be rated at least 2000. Nevertheless, there is really no limit to how strong you can be to benefit from studying the material.

My assessment of this book: 6/6"

Carsten Hansen, ChessCafe (full review)

"Will Jacob's book (Grandmaster Preparation - Calculation) make you a better player? Again I will allow the author to speak:

'You know that if you go to an Italian language course for a year you will be able to speak some Italian at the end.'

Working with this book will mean a lot of hours of struggle, sweat and tears (I had my share), but also a deep satisfaction when you see improvements at the board and realise your goals. Just remember that in chess there will always be someone on the other side of the board doing his best to make your life bitter:

'But you also know that this does not mean you will automatically be able to charm the Italian girl you want to impress!'

I give this book my highest recommendation."

GM Leif Erland Johannessen, Norsk Sjakk Blad

"Grandmaster Aagaard is an ardent believer in the benefits of hard work. With this book, Attacking Manual 1 and 2, Practical Chess Defense and the Quality Chess Puzzle Book (co-written with John Shaw) he has provided a wealth of material for the aspiring student. Whether this will help lead them to the Grandmaster title is an open question, but there can be no question that they will show serious improvement if they conscientiously work through Calculation."

IM John Donaldson 

"Aagaard is an engaging writer, and sometimes makes his points in a humorous and memorable way... In summary, this book is a workbook designed for the improving player and there can be little doubt that serious study of it will bring improvement."

Colin Purdon, British Chess Magazine

"Calculation is highly recommended to the already strong player. He gets a workout book of the highest class."
