What is the most important skill in Go? It is the ability to calculate variations. In the middle game, about eighty percent is reading ability, the rest is intuition. To improve your reading ability, you must practise life-and-death problems.
This book presents 180 life-and-death problems on the themes of Nakade (dead shape) and Damezumari (lack of liberties). The solutions are limited to a diagram, so you may have to figure out for yourself why your attempt to solve the problem failed.
