If a program is "stupid" enough to make inferior moves in an >attempt to win after the 50 moves each, that is it's problem. but what do you suggest to do if both program are not stupid to make a bad move but continuie to play. The game can continue 1,000,000 moves and it can take 100,000 hours(assuming that every side use 2 hours per every 40 moves. 100,000 hours are more than 10 years. Do you want the ssdf testers to wait more than 10 years to finish the game? I think that they have better things to do. Uri
