GGPD 300 Tesuji Problems 4d-7d
From the publisher:
Volume Two of this series started out with problems for kyu players. The problems gradually became more demanding of the reader's analytical ability and ended up with problems at the 3-dan level. This volume starts with 4-dan problems and, in the final part, the reader is challenging problems at the 7-dan level.
Taken together, Volumes Two and Five are a systematic compilation of the basic fighting tesujis that every dan player needs to know. Very few players, even those already of high-dan level, will have mastered all the tesujis presented here. Not only will careful study of them enable you to execute your fighting plans better, more importanly it will also broaden your tactical horizons by revealing to you new possibilities in the fighting and effectively deepen your understanding of go.
