Hi Thorsten, thanks for your impressions about hardware differences, especially when it is about the 68020, RISC or Tasc I am not familiar with. The somewhere around 4-6 speed difference factor is the best I could come up with so far and Christophe doesn't disagree. This Tiger-Genius match makes more sense when you know its history IMHO. Does it make sense to compair chessplaying entities when there is a huge hardware difference ? I tried this experiment : http://f11.parsimony.net/forum16635/messages/24006.htm .Just look at the hardware difference - Tiger played on the Palm Vx , the opponents on an Athlon 1333 !!! But then compair the results from Chess Tiger 14.6 with 14.9 against these opponents. This is exactly the improvement you would expect, isn't it? So a hardware difference isn't a problem per se. Then I played two matches with exactly the same conditions as in the Genius match against Yace and Comet. Tiger - Comet 4.5-7.5 Tiger - Yace 5.5-6.5 Again - as the opponents ( not the hardware) were close enough in playing strengths you get meaningful results IMHO. So the Tiger-Genius match was the next logical step. The results show that either Genius is stronger on this hardware than expected - or that the experiment suddenly shows an unexpected flaw. I hope it is easier to understand the reason for this match now. Testing opponent s against each other where one scores 11.5-0.5 usually makes very little sense, agreed. The result was more extreme than I would have expected. But I don't think the hardware difference is a general problem at all. Kind regards, Peter
