Kanzufu
|
Kanzufu is a classic problem collection originating from the mid-seventeenth century, also known as Guanzi Pu in China. It is noted as the largest problem collection from the classical period, containing 1473 problems. The first author/editor was Guo Bailing in 1660. Originally, the name implied endgame/technique problems, but over time quickly grew to include broader demonstrations in attacking & exploiting shape. For example, how to live with optimal end-game shape and how to exploit the bad shape of a defender for maximum gain. |
