If we disregard the 50-move rule, then we're left with the three-fold repetition rule as a means of avoiding infinite games. As stated, this merely allows either side to claim a draw, but for our purposes we must assume it forces a draw upon a third repetition. A superko rule may seem like a one-fold repetition rule, but is subtly different, since it forbids the repetition, rather than rule it a draw. Of course, if no other legal moves remain, then it becomes a draw by stalemate. But it may also force a player to choose a losing alternative. With either rule, chess games can be exponentially long, although determining lower and upper bounds is so much harder than in go, because of the complex piece movements... regards, -John _______________________________________________ Computer-go mailing list Computer-go@dvandva.org http://dvandva.org/cgi-bin/mailman/listinfo/computer-go
