Here is part of his post of a few days ago. <Quote> My code is still messy and there are some issues I still need to work on. With that said, I did try it out on the piece values in my program. I started the values at PAWN = 100 (fixed) KING = 10000 (meaningless, so learning should not affect it) KNIGHT = 0 BISHOP = 0 ROOK = 0 QUEEN = 0 and played a 100 game, 1 0 lightning match against GNU-chess. After the match, the parameters were at PAWN = 100 KING = 10000 KNIGHT = 296 BISHOP = 327 ROOK = 508 QUEEN = 997 <unquote> Dave
