GGPD 300 Life and Death Problems 4d-7d
The problems are presented as 2 pages with 4 problems per page, followed by four pages of the solutions to those 8 problems; for some of the more complicated problems additional diagrams are used. Each problem gets 3 solution diagrams. All problems are black to play. There are two parts (4 dan to 6 dan and 5 dan to 7 dan), each split into two chapters (Black to Kill and Black to Live). Each problem comes with a hint, as well as a suggested difficulty and timing.
