This book is a sequel to Shibano’s Fuseki Revolution. In contrast to the predominantly whole-board focus on fuseki strategy of his previous book, Shibano focuses on new josekis that have been inspired by AI go-playing programs. He also shows why a number of old discarded josekis have suddenly become mainstream and why some recently popular josekis have now been rejected.

Of particular interest is Shibano’s treatment of the taisha, the avalanche, and the magic-sword josekis. He shows how, thanks to AI, these extremely complicated josekis have been ‘swamped in a wave of simplification.’ Required reading for all serious go players.
