The computer player "GreedyG" is a strong BG engine based on the open source GnuBG AI (www.gnubg.org)
There is a section in this forum how to analyze your games using gnubg. >> viewtopic.php?f=19&t=152
Greedygammon makes it easy by saving your games in jf.mat format, launching the command line gnubg analysis
and when the analysis is complete, a clickable link will appear to open gnubg sgf file with your game already analyzed
