The middle game of go often appears chaotic, but there is order in the chaos, as this book plainly reveals. The result of a joint effort by a tournament-winning Japanese professional player and an experienced American go writer, Attack and Defense lays down a few clear principles, then goes through a wealth of applications: examples, problems, and case studies from professional play. The reader emerges with a thorough grasp of how to choose strategy, how to execute dual-purpose attacks, how to defend with contact plays, how to force his opponent into submission or cooperation, how to invade and reduce territorial frameworks, and when to fight a ko. This is knowledge that no player can afford to be without.

James Davies was born in 1945 in Philadelphia. He studied mathematics at Oberlin College and the University of Washington, but in 1970 the game of go drew him to Japan, where he has lived since.
