This book focuses on the middle game -- that time when many beginners ask themselves "now what? Do I attack, develop pieces for development's sake, or simply wait for my opponent to make a mistake?" This book teaches you how to analyze any position, determine the strengths and weaknesses of your position and, more importantly, those of your opponent. The book proceeds to discuss methods of attacking weaknesses and creating even more.
This book gave me the ability to think through a game and make a plan instead of plodding along hoping to stumble across a clever or unexpected combination.
It is written in very understandable English. I highly recommend this game to those who are seeking to advance beyond the beginning intermediate stage.
Even better, Silman includes a bibliography and brief description of the chess books he believes will be the most helpful to develop certain parts of the game (e.g. openings, endgames, pawn structure etc.). With so many chess books on the market, it's nice to have a professional's opinion on the one's best suited to help someone of my ability.
