Most games are not won -- they are lost. The vast majority of instructional books tell how to improve a position when it is already (or may be) favorable. The Art of Defense in Chess analyzes the practical aspects of not having the advantage: -- How to obtain counterplay -- When to contest open lines -- When to accept sacrifices -- How to anticipate short- and long-term threats -- How to restrain your opponent's pieces -- How to create a defense perimeter -- How to minimize losses -- And much more
The Art of Defense in Chess also discusses the proper psychological attitudes for successful defense -- coolness under fire, the Saving Grace, stonewalling, etc. -- as well as the Principle of Exploitable Weakness and the Principle of Economy, as illustrated in more than one hundred positions taken from competitive play.
