GGPD 300 Life and Death Problems 5k-3d

The problems are presented as 2 pages with 4 problems per page, followed by four pages of the solutions to those 8 problems. Each problem gets 3 solution diagrams. All problems are black to play. The specified level of the problems seems somewhat inflated compared to Graded Go Problems for Beginners -- the first hundred problems or so are similar in difficulty to the last section of volume 4 of that series, but then they become more challenging. Each problem comes with a hint, as well as a suggested difficulty and timing.

Sample problems:

Problem 51  

Solve within 3 minutes -- 1 kyu

Problem 201
