Hello Chesscomputerfriends! As I wrote in this Forum several times I'm making a new ratinglist. I am using fixed openingpositions in stead of the openingsbooks of each engine (or a common book for all engines). Here are the 10 fixed openingpositions I am using for my tests: 1. Queens Gambit: 1.d4, d5 2.c4 2. Kings Gambit: 1.e4, e5 2. f4 3. Stonewall: 1.d4, e6 2.c4, f5 3.Sc3, d5 4.Sf3, c6 4. Caro Kann: 1.e4, c6 2.d4, d5 5. English: 1.c4, c5 2.Sc3, Sc6 6. Russian: 1.e4, e5 2. Sf3, Sf6 7. King- or Grünfeldindian: 1.d4, Sf6 2.c4, g6 3.Sc3 8. Sicilian: 1.e4, c5 2.Sf3, d6 3.d4, cxd4 9. Queens indian: 1.d4, Sf6 2.c4, e6 3. Sf3, b6 4. g3, Lb7 5. Lg2, Le7 10. French: 1.e4, e6 2.d4, d5 Every engine has got to play each openingposition with both white and black meaning that a match between 2 engines consists of 20 games. I find that the chosen fixed openingpositions provide a fair mix of open, tactical and closed positional openings. I would like to thank Klaus Wlotzka (running the CSS-Ratinglist) for support and advices in the whole process. It's my aim to create a ratinglist of 25 top-engines. I'm running my tests on this 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: Windows XP Pro Hiarcs 10 GUI 10 fixed openingpositions, all openingbooks for the engines are OFF Thinkingtime for each engine: 6 min. for the whole game + 6 bonussec. pr. move Hash Tables for each engine: 64 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 Lately I have been testing The King 3.33. Here are the testresults: The King 3.33 – Fruit 2.2.1 7½-12½ The King 3.33 – Hiarcs 10 6-14 The King 3.33 – Toga II 1.1a 7-13 The King 3.33 – Fritz 9 9-11 The King 3.33 – Shredder 9 5-15 The King 3.33 – Spike 1.1 8-12 The King 3.33 – SmarThink 1.00 8½-11½ The King 3.33 – Ktulu 7.5 9-11 The King 3.33 – Gandalf 6.0 14½-5½ The King 3.33 – Naum 1.91 11-9 The King 3.33 – Loop List 600 12-8 The King 3.33 – Glaurung 1.0.1 13-7 The King 3.33 – Ruffian 2.1.0 10½-9½ Generally The King 3.33 made a fine performance. 9-11 against Fritz 9 and a quite huge 14½-5½ victory against Gandalf 6.0 are good results. As a result of the latest testresults the ratinglist now looks like this: Program Elo + - Games Score Av.Op. Draws 1 Fruit 2.2.1 : 2755 36 36 260 63.3 % 2660 31.2 % 2 Hiarcs 10 : 2752 37 37 260 62.9 % 2660 26.5 % 3 Toga II 1.1a : 2736 35 35 260 60.6 % 2662 33.5 % 4 Shredder 9 : 2720 36 36 260 58.1 % 2663 29.2 % 5 Fritz 9 : 2717 36 36 260 57.7 % 2663 29.2 % 6 Spike 1.1 : 2706 35 35 260 56.0 % 2664 32.7 % 7 SmarThink 1.00 : 2661 35 35 260 49.0 % 2667 32.7 % 8 Ktulu 7.5 : 2652 37 37 260 47.7 % 2668 23.8 % 9 The King 3.33 : 2645 35 35 260 46.5 % 2669 32.3 % 10 Naum 1.91 : 2612 34 35 260 41.5 % 2671 34.6 % 11 Gandalf 6.0 : 2611 36 36 260 41.3 % 2671 28.1 % 12 Loop List 600 : 2603 37 38 260 40.2 % 2672 23.5 % 13 Glaurung 1.0.1 : 2586 38 39 260 37.7 % 2673 20.8 % 14 Ruffian 2.1.0 : 2585 36 36 260 37.5 % 2673 31.2 % All engines are playing with their default-settings with exception of Hiarcs 10 which is being tested with Hypermodern ON. The King 3.33 enters the list on a decent 9th position with a rating of 2645. Before starting the test of The King 3.33 I was expecting a performance comparable to the one of Naum, Gandalf and Loop List but as you see I was a bit wrong. Fruit 2.2.1 managed yet again to defend its topposition but Hiarcs 10 remains in the neck of Fruit. Shredder 9 regained rank 4 from Fritz 9 and increased the gab to newcomer Spike 1.1 to 14 points! Still, it's worth emphasizing the great performance of free-ware engine Spike 1.1. As soon as Rybka 1.1 is available I will naturally test this extraordinary engine but in the meantime I'll make another test for my ratinglist. Next engine to be tested is Pro Deo 1.1.
