There could be something to that. Do you believe that they will play the 90% move if they are told they are not really down 9 stones? I did a bunch of experiments and ALWAYS got a reduced wins when I faked the komi. But there are a million ways to do this and I may not have stumbled on the right way. - Don > > Darren > > _______________________________________________ computer-go mailing list computer-go@computer-go.org http://www.computer-go.org/mailman/listinfo/computer-go/
