I would like to know the relationship is between computers playing strength (relative to humans) under different time controls. When I for example play Rebel 8 in 5 min or 10 min (on a 366Mhz machine) it vipes of my butt. Already Genius 4 had (it was claimed) around 2800 in "blitz" rating on a pentium. This does not seems right and I usually beats Genius (and Rebel 8) on a 90mhz in 10 min games. We know that the rating roughly goes up 70 point when the clockfrequence is doubled. If we assume this is also the case for blitz rating it should be possible to come up with a (crude?!) formula of calculating a machines rating (against humans) on different machines and with different time controls. It seems to me Rebel 8 (on a 366Mhz machine) have around 3000 in blitz rating, but this is not a scientific claim and it could be off some hundreds in either direction. Based on the huge experince of machine-human games (on many different machines and time controls) can someone suggest a reasonable formula? Soren Riis
