I realize that statistically i am suppose to win some of the games, but i >have been winning almost half!!, against much faster machines. However when i >play my rebel 9 on the 486 it never wins, but draws often. First, it depends on the number of games played. It is possible to win or draw against programs that are up to 734 rating points higher (1% of wins/points statistically, according to the Elo table). Did you play the games in ICC? As Robert Hyatt reported, one good thing of being manual in ICC is that YOU can let the program thinks longer in complicated situation, and shorter for obvious move (more flexibility). Secondly, Genius is a good program at fast time controls (according to Komputer Korner, it is the #1 program at blitz time controls and against other programs/computers. But IF you decide to upgrade to a faster/more memory machine, that would DEFENITELY make the program stronger. Finally, Genius has a more "positionnal" style of play that makes it avoid too risky moves and try to keep everything under control. So, it mainly avoids tricky and tactical melee that could lead to a lost position beyond its horizon. Serge Desmarais
