Yes, I had realized it. I had been referring the hardware-software combinations. Extrapolating this result to equal hardware results in a probabiltity that Fritz may be stronger. However, one should be aware that in view of the number of games (46) the statistical uncertainty is still larger than 100 ELO. A numerical example. Let's say the result on the above hw was 50%. Then a rough estimate is that Fritz has a 70 ELO advantage (resulting from the hw disadvantage). With a statistical error larger than 100, one can still not exclude that Sjeng is stronger - even on same hardware. However, the result seems rather to indicate some advantage for Fritz. Nevertheless, I think that Sjeng's result in this match isn't bad at all. 50 - 80 ELO behind Fritz is a good result for a newcomer, imho. Uli > Kut
