Go back to r.g.c.c archives. Somewhere in that timeframe I ran a match with genius 2 which was stronger than mephisto. I gave genius 2 a 30:1 time handicap running cray blitz on one cpu (rather than 16 as we had in 1989 since the C90 was out). Cray Blitz was winning nearly every game although I no longer remember the specifics... As for what he meant by 'fundamentally stronger' I don't know. If he meant on 'equal hardware' where CB ws run on hardware identical to mephisto, he might have been right since CB was absolutely optimized for the Cray with some 20,000 lines of assembly. If he meant that both on the C90 would find mephisto stronger, he was dead wrong. And if he meant that mephisto on the 030 was stronger than CB on the c90 he was wrong beyond his worst dreams.
