I think it's very possible that Hitech could consistently lose 3 out of 4 against modern stuff running on the best hardware, which is what is required for a 200 point delta. I don't think that you make a very strong argument when you take a national rating against humans, convert it to a FIDE rating, estimate the FIDE ratings of current computers against humans, then compare. Every aspect of this is controversial. You could start a 50-post thread about how to convert from USCF to FIDE, for instance, not that I have any intention of starting it. Computer chess people have always had two problems to solve -- computer vs human, and computer vs computer. I think that they are very distinct problems. People who used to use supercomputers to play against 80286 machines were not receiving much of a challenge, and who knows what kind of bizarre thinking was adopted without there being much difference in outcome. Everything you do looks like genius when your opponent is searching 5 plies. I think the disadvantage of having to pioneer, combined with the lack of readily available serious computer competition, is such that I doubt that Hitech would do very well against modern programs running on superior hardware. The micro programmers have travelled in a competitive herd for years. Everyone knows if they are weak or strong. If they are weak, there is great incentive to make changes in order to get strong -- despair because someone else outsearches you by a ply on the same hardware is a powerful motivator. This has to result in stronger computer vs computer play than working in a near-vacuum for years. bruce
