Without looking at the logfile the rules of getting a draw score for 5 or 3 consecutive moves can be illogical rules in some cases. It means (if I understand correctly) that Crafty is not going to accept a draw in the relevant position(assuming it had a losing position 3 moves ago). I do not say that Crafty should accept a draw after one draw score but it should accept a draw when it has only a king. Uri
