Wow. Somebody needs to put up a five-star review of this book: so here goes.
This is a great book, one of the greatest chess books ever written. I devoured this book as a kid (in the old descriptive notation), and highly commend this to any one today.
It's not just that Fischer was a great player, arguably the greatest of all time. He was also a great chess writer: interesting, clear, simple, and instructive.
This is one of a handful of books that is simply a must-read for any player hoping to improve their chess. If you want to learn how to launch an attack, you need to study Fischer closely: one of the all-time great masters of attack. A careful reading of this book will probably teach you more about modern chess strategy than Nimzovich's classic "My System." It will probably teach you more about endgames than most modern endgame manuals.
As with most game collections, you need to go through it line by line, and ask yourself at each point: what is the best move?--and then see what Fischer actually played. When you get to a move that Fischer analyzes in detail, you need to set aside the book, write out your analysis, and then compare your analysis with his. This book is the perfect follow-up book for anyone who has read Silman's "How to Reassess Your Chess" or Kotov's "Think Like A Grandmaster".
