When we began to test Naum 3.1 on Q6600 2,4 GHz it was his latest program version. After 358 tourna- ment games itīs rating is 3046, which makes it the fourth strongest program on the SSDF Rating List. Frans Morschs Deep Fritz 11 running on Q6600 2,4 GHz takes the second place on the list With 3085! Compared to Fritz 11 on Athlon 1200 MHz, the rating increase is 166 points. Deep Rybka 3 has now also been tested on Athlon 1200 MHz, which resulted in a rating of 3066. As expected Vas Rajlichs program is strongest also on this slower single processor. On this hardware Deep Rybka 3 has 141 points more than Rybka 2.3.1 A1200, and 161 points less than on Q6600 2,4 GHz. Thoralf Karlsson
