The 3 golden pillars of winning chess are undoubtedly TACTICAL sharpness, STRATEGICAL insight, and CALCULATION accuracy. Visualising future positions accurately is fundamental to playing winning chess. STEP by STEP methodology is combined with playing through 94 marvelous games starting with Morphy-> Capablanca-> Fischer-> Kasparov-> working up towards modern day grandmaster games. (from 1 move ahead two 1/2 moves] to 10 moves ahead twenty 1/2 moves] ). Thus the book is written for beginners as well as players right up to grandmaster level.(Of course it is not expected for a beginner to think 10 moves ahead. From beginner-grandmaster: concerning chess calculation training exclusively). Highly recommended .

In this extraordinary book, the author also recognises the importance of ethics BEYOND the chess board {chapter 8}. Optional animal metaphor's are used for only 5 tactical terms, namely for pin, fork, skewer, double attack and discovered attack. (These terms however are not used anywhere in the 320 pages of calculation training).
