I don't know for sure, but I suspect that even if it means that it would not play out a bad ladder, the UCT would still see it as a desirable thing, and direct the game towards one - and then not play it. Plus, it is not quite trivial to recognize a bad ladder - some times it pays off to extend a stone that is in atari, and then sacrifice two stones. Some nakade shapes also require sacrificing more than one stone... - Heikki -- Heikki Levanto "In Murphy We Turst" heikki (at) lsd (dot) dk _______________________________________________ computer-go mailing list computer-go@computer-go.org http://www.computer-go.org/mailman/listinfo/computer-go/
