Also many draws could been seen in a much earlyer stage pointing at an intact pawnstructure on both sides with the a pawn on the kingside and also both kings on the kingside this can be a win in some cases but most of the time it's a draw so a decreasment of the evaluation of such positions could help. So these positions would not arise anymore. I think the game I pointed to was a good example of this.. Nice that see you have Capablanca's book chess strategy too. Regards Marc
