|This ancient chinese text contains 1454 challenging problems. It's know as KanZuFu in Japanese. The English translation is roughly 'Manual of Endgame Positions.' However, these aren't endgame problems in the typical sense: they're problems wherein if you could solve one in a game, the game would end, as you'd have just killed a large group or saved some crucial stones.|
The original book was split into three parts, a start, a middle, and an end. In referencing these problems, I've indicated from which part originated the problem, along with the problem number.
