A computer program that plays Go (Weiqi). You will be able to download it here after it has been released.

Wei2go is written in Java. Building upon the Monte Carlo Tree Search (MCTS) breakthrough, Wei2go benefits from a unique balance between ancient knowledge and brute force.

The first release will probably be free and somewhat experimental, somewhere around January 2011. If it ever goes commercial it will probably focus on playing strength, and leave a fancy graphical user interface and learning tools to other programs. They will communicate over GTP, (Go Text Protocol).

You can follow the development of wei2go on KGS, as the current issues are listed in the user info of wei2go [-].
