Many books discuss how to attack in chess, but good, resourceful defensive play is also a vital ingredient in competitive success. However, this is an area largely neglected in the literature of the game. This book fills the gap admirably, by explaining the basics of defending against direct offensives, and taking an in-depth look at how the all-time greats have fended off their opponents' attacks. Following a survey of general defensive methods in chess, Dr. Crouch investigates the defensive techniques of World Champions Emanuel Lasker and Tigran Petrosian. Despite their vastly different styles, Lasker and Petrosian were both highly effective defenders. Lasker would place myriad practical obstacles in the opponent's way, and was a master of the counterattack. Petrosian developed Nimzowitsch's theories of prophylaxis to a new level. His opponents would find that 'somehow' their attacking chances had been nullified long before they could become reality.
