Tsumego

is the Japanese term for a type of go problem based on life-and-death. The term likely comes from , as means checkmating in shogi but has different meanings in go. Tsumego problems are common in newspaper columns.

Tsumego problems have been found in Chinese books dating back to around the 13th century. They were presumably composed and collected from actual games much earlier. They range from situations that occur quite commonly, which every strong player ought to be familiar with, to deliberately difficult puzzles. Some books of the latter type are still used for professional training.
