Amir directly implied that I am a liar. I responded. back up and read again.

I dare say that Crafty on a couple of machines I have used in the past two years is not behind _any_ of those. IE last year a 21164 X 16 running at 7M nodes per second (I was going to run on that box for the WCCC in Paderborn if I could have worked out details to get there.) Crafty on a 21264/750 will probably do about 20M nodes per second. If you think it is 'behind' given the right hardware, if you see a bright light in your rear-view, you had better get _out_ of the way. Not fair? Says who? I spent a year getting the SMP search to work. So I consider that to be fair game. > >As a measure of how much it is behind I would say that in my opinion it is at >least 100 elo points behind. > >That's HUGE. > >That's why I think Tiger on a PII-400 would stand Crafty on Quad-Xeon. >Unfortunately I have only a K6-2-300, so I'll have to try the experiment (if Bob >agrees) with a 4x handicap, which probably translates to a 120-160 elo points >handicap. > >Is it that distateful to point out that Crafty is so far behind? > > > > Christophe We need two tests: A significant crafty vs tiger match. Then a significant computer vs a couple of good GM matches. You will find "cptnbluebear" _not_ to your liking. I _know_ how I do against the strong humans. I don't worry about how I do against computers. The GM comparison would be an interesting test. We could probably get him to play two game matches all day one day, 2 vs you, 2 vs me, over and over... He _loves_ to do that.
