Of course it would be better to run all matches on equal platforms, but this does not disqualify results Fritz 5 got in matches on uneven computers. SSDF always did this with the 59,000 games they played so far. Fritz 5 played both, matches on two P200MMX and on P200MMX vs. P90s. Like all other top programs recently: Rebel 8 and 9, Hiarcs 6, Nimzo98, Mchess 6 and 7, Genius 5… Also these programs played matches on P200MMX against P90s. In the use of different platforms I don’t see anything atypical that allows singling out Fritz’s case. Enrique
