The art of defence in chess - Andy Soltis

Most chess games are not won - they are lost. Many instructional chess books tell you how to improve a position when it is already (or may be) favourable. This book offers help when you definitely do not have the advantage.
Every chess player needs a sound arsenal of defensive techniques. This book covers them all - counterplay, when to accept sacrifices, how to anticipate short- and long-term threats, and how to minimise losses. It also helps you create a strong underlying psychological framework for defensive technique - it teaches you how to stay cool under fire, how to stonewall and how to exploit your opponent's weaknesses.
