[ Does everybody like "new" ideas? : ) ] I don't think this is such a new idea, Bob. The dedicated chess computer Novag Scorpio 68000 has a BEST MOVE/RANDOM button. When RANDOM is selected the computer randomly chooses between two or more moves which are almost equal in evaluation. This I believe is a 1991 machine and is probably not the first Novag to have such a feature. Geoff > >Bob D.
