STOP

STOP is my GO (Weiqi, Baduk) playing program.
It is a go-brain; a program that decides by itself what counter-moves to do for each move the user types in.

What is Go?

Wikipedia defines Go as: "Go is a strategic board game for two players. It is also known as igo (Japanese), weiqi or wei ch'i (Chinese) or baduk (Korean). Go is noted for being rich in strategic complexity despite its simple rules.".
