Grandmaster Andy Soltis has revised The Inner Game of Chess [Mongoose Press, 2014, 324 pages], originally published 20 years earlier.
New games Kamsky-Mamedyarov, World Cup 2013; Ivanchuk-Harikrishna, FIDE World Championship 2004; Carlsen-Anand, Moscow 2013; Nisipeanu-Ivanchuk, FIDE World Championship 1999; and Sasikiran-Short, Skanderborg 2003 have been added.
According to the author: "Chess is really 99 percent calculation - the inner game of chess."
The Table Of Contents includes chapters on calculation, ideas, and analytical trees.
Because each game teaches a valuable lesson, I intend to use this book in coaching my students.
