1001 Life and Death Problems

Shortage of liberties could mean Atari. It is the purpose of this book to provide a vast number and a large variety of life-and-death problems for the inexperienced player. The problems here are not hard; they range from very easy to moderately difficult. A dan player should be able to solve them within a minute, sometimes on sight, but it may take a bit longer for kyu-level players.
