It's the low number (2) of opponents. Suppose that Nimzo for some reason does better against Junior than against others (or the other way around) then your results will bias against that, regardless of how many games you play. If you are trying to predict how games, with exactly the used PC:s, between these two programs only will turn out, you have som good data. >PS: I am still convinced that Nimzo 8 is one of the few programs just like >Gandalf 4.32 that benefit the most by using the best hardware available.

If this is what you are trying to prove then we have a different story that shouldn't be compared to the SSDF tests at all. //Peter
