Uri, you're a chuckle! Hsu and team had ALREADY MADE A WORLD CHAMP - DEEP THOUGHT. Then they re-did it with TWO more revisions, DB and Deeper Blue. Increasing it's hardware, which as has been mentioned, is the biggest factor in chess computer improvement in the past 20 years. (Try running Fritz on a real clunker CPU/system for a hoot!) Then they increased it's software side with lots of GM input. But because of a move here, a move there, (and HSU has stated that DB had a bug causing it to not always select the best move it found), some guys decide: ** That's not good! ** When you read what Hsu wrote, you know right off - the guys a total bright bulb, and he was totally into computer chess. Oh, and his team had several other Ph.D's with lots of experience, also working on DB. Lots of backing from IBM. If a bunch of Ph.D's and/or World chess champions programmers (who had nothing to gain from saying it, monetarily), were saying "DB is not as good as Fritz on a good PC", I'd consider that. But when I hear people who can NOT program a top chess player, go on and on about "this move" or "that move" of DB being bad, well that just doesn't cut it with me. Every program plays questionable moves now and then. We've seen thousands of them in CCC/rgcc over the years. They're useless for any kind of meaningful comparison of strength, and you know that better than most, I'm quite sure! I'm not concerned about DB never playing Fritz on equal hardware. If you could somehow compare just the software, because of the on-going work on Fritz, it might be stronger than DB. But that's my point - you can't. Deep Blue was hardware just as much as software, and that's why Deeper Blue still would be world champ today if it was playing. Some day, a program (and system) will be stronger than DB, but that's not happened yet. And it won't happen on a 600MHz laptop, no matter how much Kramnik may want it to make us believe it, for his own financial gain! <chuckle, chuckle> Dave >I think that every result that is not convincing win for kramnik is a surprise >under these conditions. I think you're putting your own spin on this, Uri. If Fritz is better than DB on a little laptop, it should kick Kramnik's butt to the moon on a hot 8 CPU monster, with all those "better" algorithms.
