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 were as follows: Fritz 9 - Fruit 2.2.1 19-11 Shredder 9 - Fritz 9 18-12 Shredder 9 - Fruit 2.2.1 11½-18½ A couple of hours ago the test of Toga II 1.1 ended. I was very excited to see if this Fruit-based engine would go all the way and conquer the topposition of my ranking. As the results show it didn't quite make it: Toga II 1.1 - Fritz 9 14-16 Toga II 1.1 - Fruit 2.2.1 10-20 (!) Toga II 1.1 - Shredder 9 16-14 The results against Fritz and Shredder are probably quite expected but that Toga suffered such a big defeat to Fruit was a surprise to me. Also the Drawfrequency was a bit of a surprise: in the 90 games Toga played 38 draws = 42%! Thanks to the huge victory Fruit 2.2.1 has replaced Fritz 9 in top of the ranking: 1. Fruit 2.2.1 49½ 2. Fritz 9 47 3. Shredder 43½ 4. Toga II 1.1 40 I have already started the next test and this time Loop List has to prove its qualities. In app. 100 hours I'll have the result (one game lasts in average 50-55 minutes) and I'll post it here in CCC-Forum. Best regards Per
