Hello Uri, He did state above he had two computers and listed only the P400, so let's assume for the moment that he has two identical computers. I have tested Hiarcs with 131 megs and 64 megs and found it made the same moves. Hiarcs, I believe, does not use HT as Fritz and therefore will only use a very small amount of even 64 megs. On the other hand, as I have stated to you before, Fritz is very dependant on the amount of HT available. On a Pentium 400 Fritz needs 144 megs! The testing run above with Fritz getting 120 megs is a lot more than what Tania is giving Fritz. Without knowing the time control, although from testing done at fast time controls Hiarcs clearly is better than Fritz, I would assume he tested at a reasonable time control and hopefully at 40/2 but we'll have to wait for his reply. I know his results are surprising but then the SSDF tested Hiarcs 7 against Fritz 5.32 at 40/2 and the results were 22-18 in favor of Fritz!
