I heard that it costs $10,000 is that true? If it is and i was chessbase I >would do it. I still think the SSDF is a good measure of strength. No measure is exact. The SSDF and the 520 HvsC games are good measures, but not identical or exact. I think FIDE no longer allows computers in FIDE rated events, so this will be the best that we can get unless FIDE changes its policy. I also believe the faster hw continues to make a program play better, there may be diminishing returns, but for now, there continues to be improvement. If you go back and compare the HvC numbers you get 180 point difference for DJ6 on 450mhz vs 8X700 (and I am not sure about the 9x speedup, I would need the NPS comparison, not sure DJ6 published that, SMP's loose some as the number of processors goes up and I am not sure what the ration for DJ6 is, I have not seen it published). SSDF is about 75 points higher than the HvC games on the 450mhz, the SSDF rating for DJ6 will most likely go down when the new 1.2GHZ machines get here and will be closer to the HvC rating, but probably not an exact match, doesn't need to be). Anyway, 75 points above the HvC games on similiar HW is not much of a difference and humans have same variability all the time between tournament and established ratings, then their ratings change. Another option is to publish your own list as many others do and I enjoy reading them all (ELH, Chessbits, Frank's page, Shep, LCTII, others). :) My hats off to everyone that contributes to this venture. :) Best Regards, Chris Carson
