GoSP is a GUI for game of go. It allows playing against GNU go, but its main purpose is not really to play against but to train with GNU Go. It implements some features of the Go Text Protocol which are usually not supported by other GUI or go programme. Those features allow the user, while playing against computer, to break the rules of game by
* playing several consecutive moves with the same color, * forcing the computer next move, * inverse your color with computer, * undoing several move to try an other variation,
and then asking the computer to keep going playing as if nothing had happened. Those features, associated with GNU go's joseki databases and deep reading capacity makes it suitable for the study of joseki and tsumego where many variations can be tryed. It can also be used to review a play alone, making comparaison between our moves and GNU go's moves.
GNU go is ranked as a 10 kyu player on KGS server. If you go level is far better than 10 kyu, playing against GNU go is not a challenge for you, and you may prefere look for a human patner.
