Hi Charles, I know it is frustrating for testers but don´t trust your tests. They have too few games to draw conlusions about relative strength between chess engines. Take a look at tournaments with lots of games (example CEGT with more than 1000 games per engine). There you´ll find a good raiting for rybka and you will find out that rybka is far stronger in engine vs. engine contests than for example Fritz 8 on equal hardware. Reducing the hardware speed will reduce the elo of an engine, even of Rybka. Perhaps you can add about 30 Elo for doubling the speed, thus an engine on an Athlon 64 will play 60-90 Elo stronger than an engine on a PII with 450 MHZ. If now Rybka is more than 60-90 Elo stronger than the competitor engine it will still play better on such an old hardware. Greetings Volker
