Hello Chesscomputerfriends! Several Months ago I got the idea to make a Ratinglist similar to the one Klaus Wlotzka is making for CSS (Computer Schach und Spiele) but with one important difference. While Klaus is testing with 10 min. for the whole game plus 10 sec. per made move I would be testing with only half the time (5+5). Fortunately Klaus thought it was a good idea and I would like to thank him for support and advice during the process. I did a lot of testing and I managed to develop a Ratinglist of 17 Engines (each one having played 320 games). At that time I realized that my Hardware wasn't strong enough to cope with the needs of modern Engines (especially Fritz 9 which in my opinion requires at least 512 kb Level 2 Cache to perform at its maximum). Consequently I have purchased new 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) A couple of days ago I started the new testseries and I'm still playing with the thinking time 5+5. As mentioned earlier I am testing the way Klaus Wlotzka is doing: 10 basic openingpositions that each engine has got to play with white and black meaning that an Enginematch equalizes 20 games. If you are interested in further details (like the specific openingpositions) I refer to the excellent Website of CSS: www.computerschach.de. It's my aim, just like Klaus Wlotzka, to develop a Ratinglist of app. 25 Engines. So far I have been testing 5 Engines and here are the results: AMD Athlon 64 4000+ 64 MB PC 3200 Ram (CAS Latency 2-2-2-5) 8 MB Cache for TB's TB's: Nalimov - 3 + 4 Pieces Pondern Off Fritz 9 - Shredder 9: 11½-8½ Spike 1.0a Mainz - Fritz 9: 7½-12½ Spike 1.0a Mainz - Shredder 9: 8½-11½ Fruit 2.2.1 - Fritz 9: 6-14(!) Fruit 2.2.1 - Shredder 9: 11½-8½ Fruit 2.2.1 - Spike 1.0a Mainz: 14-6 The King 3.33 - Fritz 9: 7½-12½ The King 3.33 - Fruit 2.2.1: 6-14 The King 3.33 - Shredder 9: 9½-10½(!) The King 3.33 - Spike 1.0a Mainz: 10-10 And here is the current standing in points after each engine have played 80 games: 1. Fritz 9 50½ 2. Fruit 2.2.1 45½ 3. Shredder 9 39 4. The King 3.33 33 5. Spike 1.0a Mainz 32 I guess that this standing is not a big surprise but at least 2 things are remarkable: 1) The King 3.33 have so far made a very strong performance and perhaps this huge and comprehensive Programme benefits from my quite fast Hardware and 2) Although each engine have only played 80 games Fritz 9 leads Shredder 9 by more than 10 points! When I made my last Ratinglist on my old Hardware Shredder 9 was app. 30 Ratingpoints ahead of Fritz 9, I certainly don't expect this to happend again! The next engines to be tested are Ruffian 2.1.0 and Loop List. Best regards Per Jørgensen
