Hello Chesscomputerfriends! As I described in this Forum on the 29th of November I'm making a new Ratinglist based on 15 openingpositions. 10 of these are known from the CSS-Ranglist (for further information check this website www.computerschach.de), here are the 5 new openingpositions: C30 = Kings Gambit (1.e4,e5 2.f4) E17 = Queenindian (1.d4,Sf6 2.c4,e6 3.Sf3,b6 4.g3,Lb7 5.Lg2,Le7) B02 = Scandinavian (1.e4,d5 2.exd5) D35 = Orthodox Queens Gambit (1.d4,d5 2.c4,e6 3.Sc3,Sf6) A57 = Modern Ben Oni (1.d4,Sf6 2.c4,c5 3.d5) It's my intention to create an élite Ratinglist of 16 engines so that each engine has played 450 games (30 x 15) when the list is full. I'm testing on the following Hardware: Asus A8V Motherboard, Socket 939, FSB 1.000 MHz AMD Athlon 64 4000+, 2.4 GHz, 1 MB Level 2 Cache, 90 nm San Diego Core 2 x 512 MB Corsair PC 3200XLPT RAM (CAS Latency 2-2-2-5) And here are the specific testconditions: Shredder 9 GUI Thinkingtime for each engine: 40 moves in 14 minutes repeatedly Hash Tables for each engine: 128 MB PC 3200 Ram (CAS Latency 2-2-2-5) 8 MB Cache for TB's TB's: Nalimov - 3 und 4-pieces Pondern OFF I have already started the new testing and the first result was: Fritz 9 - Fruit 2.2.1 19-11 And here are the newest results: Shredder 9 - Fritz 9 18-12 (!) Shredder 9 - Fruit 2.2.1 11½-18½ Although the results from the CSS-Ratinglist clearly shows that Fritz 9 is having some troubles with Shredder 9 under these testconditions (Shredder 9 won 11½-8½ against Fritz 9) it was still a surprise that Shredder 9 was able to win with such a margin. In the other match Fruit 2.2.1 recovered from the big defeat against Fritz 9 and scored a nice victory against Shredder 9. The current standing after these results: 1. Fritz 9 31 points 2-3 Fruit 2.2.1 and Shredder 9 29½ points The next test has already started and this time it is Toga II 1.1. I'm excited to see how this Fruit-based engine will performn and to see if this engine will replace Fritz 9 in top of the table. So far 15 games are played and here is the current standings: Toga II 1.1 - Fritz 9 2-3 Toga II 1.1 - Fruit 2.2.1 3-2 Toga II 1.1 - Shredder 9 2½-2½ Very close and equal. When the matches are done I'll post the results here in this Forum. Best regards Per
