American Go E-Journal

“Attacking and Defending Weak Groups,” a new book by Richard Bozulich, is now available both as paperback and in digital form in the Go Books app. Weak groups are a crucial factor in the middle game of go, and this book covers all the techniques of attacking and defending weak groups. Each of the first nine chapters starts with a few examples of the technique under study, then continues with a few problems showing how that particular technique was used in a professional game. The tenth chapter presents additional problems whose solutions draw upon the techniques studied in the preceding nine chapters. The book is available in paperback from Kiseido and in digital form in the Go Books app for iPad, iPhone, and Mac. Regardless of which version you get, you can download the professional games used for the problems here.
