The absolute truth (when pass is the best move) is not relevant to the current state of the art. The only case that matters, where a pass is the best move globally, is when the game is over.
A program should only pass when some heuristics suggest the end is near (board nearly full, etc) and when all the non-pass moves it considered have negative evaluations. _______________________________________________ computer-go mailing list computer-go@computer-go.org http://www.computer-go.org/mailman/listinfo/computer-go/
