When Bob's argument goes south, he has to up the NPS to 1Billion (in a year it will be more based on something only he knows about and was never before disclosed to anyone else) or up the number of chips or talk about DT vs 6502/386/486 machines or something. IBM tried to get the most hype out of the match (nothing wrong with that, they were paying for it) and put out the best, most flattering picture of DB they could, they left out the 95 lose at the WCCC to Fritz3 and the fact that they had not won a WCCC since 1989 (Chessmachine 1992, Fritz 1995, Shredder 1999). All the hype anyone needs is on the IBM pages. The easiest way to change my opinion is to show me some legitimate publication (book, ACM journal, Scientific America article, ...) with new facts. HSU and Murry have not published anything that supports many out rageous statements made here. I believe they would if there was more to tell. Silence says a lot. Deep Blue was a great achievement. I would still make it a favorite by 25% today (3 years later). It was very impressive. It is dead. Next month the Px-1.5GHZ will be out and by next year the 8x-700 will be 50% or more slower than the fastest multi-processors. Next year, I would give any ot the top commercials on the fastest multi-processors equal to 25% chances over DB 97 and in 3 years, I would give any of the top commercial programs on single processors equal to 25% over DB 97. This may be to conservative considering diminishing returns for the multi processors and the amount of improvement and continued improvement in the comercial programs strength (Rebel, Chess Tiger, Deep Junior, Fritz, Hiarcs, Shredder in no particular order). DB had it's day and it is over (DT's performance has been surpassed, DB 95 HW surpassed, DB 96 performance has been surpassed and DT 97 was only twice as fast as DB 96). DB is dead, long live the new programs/hw/programmers. :) Hey, do not take my word for it, research it yourself, come to you own conclusions, talk about it here if you like. I can accept an opinion, I do not accept opinions as fact without documented proof, but that is just me. :) Best Regards, Chris Carson
