GG robots are neural-net backgammon players.
They are able to play at a very high level. Besides being a superb opponent, it can help you learn to play better. It can analyze your saved matches, and show you where you could have made better checker plays and cube decisions. The GG robots were developed by GamesGrid Engineering, based on the GNU Backgammon 0.10 open source. We improved the n-ply evaluation algorithms, which will be contributed back to the GNU effort.
