Excellent! :))) >Ed, if I am wrong, please let me know. Just one comment for Rebel9. Rebel9 is even more selective than Rebel8. That's very good for fast Pc's hitting new incredible ply depths. From my AUTO232 tests on relative slow Pc's (Pentium 90) I get the impression that this narrowed selective search pays even more. For Rebel9 I believe an overall engine improvement has been made of 30-40 ELO. It's a difficult topic so I am careful here but I for the moment think: - Rebel9 (Pentium 90) improvement of 40-60 ELO above Rebel8. - Rebel9 (P200 or higher) improvement of 20-40 ELO above Rebel8. This conclusion is based after I removed from all played AUTO232 games all the doubles and also removed the effect of the book learner as far that is possible of course. - Ed Schroder - >And what is the opinion of other programmers about this theory? > Christophe
