And the answer is that the program _did_ claim the draw properly. The human failed to handle it properly because he thought he had the right to supercede the program's wishes, which was wrong of him. Most every program I have seen claims draws properly... There are two cases. It is your move and the position has already occurred, you can claim a draw immediately. It is your move, and by making a particular move you repeat the position a third time. You write the move down, tell your opponent "I am going to play this move and I claim a draw because the resulting position is a 3-fold repetition" and call the TD. In the WCCC the human is an operator, not an active participant. That wasn't upheld here. The operator made an intentional error that penalized his program and another entrant "Fritz". That is not allowable, except when you have an oddball group running a tournament where "rules are meant to be broken." > >Perhaps there is room for improvement in the software associated with such >offers. > >There seems to be an issue as to whether the decision software should be in the >engine or in the GUI.
