Hello Chesscomputerfriends! In the last couple of Months I have been making a Ratinglist which is comparable to the one Klaus Wlotzka is making for the CSS. For readers who are not familiar with the CSS-Ratinglist I should mention that this list is based on enginematches of exactly 20 games. It is 10 basic openingpositions that is the fundament for the enginematches and each engine has got to play each openingposition with black and white resulting in 20 games in each match. The only real difference in testconditions between me and Klaus Wlotzka have been the Time controls: Klaus is testing with 10+10 while I have been testing with 5+5. During my testwork I have discovered several disadvantages in testing 5+5 and that's why I have decided to start a new way of testing which not only includes longer Time controls but also 5 new openingpositions: - The new Time control is 40 moves in 14 minutes repeatedly - I have kept the 10 original openingpositions but have included 5 more: 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) I would like to thank Klaus Wlotzka for support and good advices. 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 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 here is the first result: Fritz 9 - Fruit 2.2.1 19-11 (14 wins, 10 draws and 6 defeats) A quite convincing and comfortable win for Fritz 9 although the result was worse than the one I got when I was testing 5+5: 14-6 meaning a score of 70% while the new victory was "only" 63%. Still, a very strong performance by Fritz 9. I'm very curious to see if the following tests will follow the pattern from my 5+5 testing in which Fruit 2.2.1 reduced the gap to Fritz 9 by winning the next matches with a bigger margin than Fritz 9. We'll see. I have already started the next test which is Shredder 9. I'll post the results here in the CCC-Forum as soon as they are ready. Best regards Per Jørgensen
