This is not a "How to" book, despite its title. The advice it presents are few and rather superficial, and mostly bunched into the last few pages.This is more of a descriptive study and self-knowledge guide, with half of the book consisting of various tests and their solutions. Some of these tests are rather instructive, but IMHO they have little to do with the subject of training your chess thought. Of course, doing the excercises will improve your play, so this is not a useless book.This is definitely not for the beginner. You will also need an interest in psychology and the associated jargon to enjoy this book.
