Honkaku Igo

Honkaku Igo is a digital conversion of the ancient Chinese board game Go, featuring a play algorithm devised by David Fotland. The game includes standard play against a second player or a CPU opponent at one of five different skill levels. There are multiple board size options -- 9x9, 13x13, or a full 19x19 -- as well as optional handicap and time limit options. There is also a Go school with information for beginners on game rules and strategy.
