My program is up 1 to 3 minor pieces and CM6000 finds repetitive moves to make and the game ends up in a draw. I am thinking of keeping an Array of bitboards and scanning through them for duplicate positions. If my program is behind in material, then I would assign a bonus for making repetitive moves. If my program is ahead in material, then I would assign a penalty for making repetitive moves. That reminds me, I need to get en-passant implemented as this is hurting the strength of my program. Good Luck! Larry.
