Hi all :-) , a database with 203 short tactical games is updated. All games with 40/40 (adapted to 2 Ghz P4 CPU). Two examples: in one Spike with a devastating sacrifice against Junior, the other Glaurung at its best: [Event "CEGT 3"] [Site "CEGT"] [Date "2005.04.28"] [Round "2.7"] [White "Spike 0.9a"] [Black "Junior 9"] [Result "1-0"] [ECO "C49"] [PlyCount "35"] [EventDate "2005.04.23"] [EventType "tourn"] 1. e4 e5 2. Nf3 Nc6 3. Nc3 Nf6 4. Bb5 Bb4 5. O-O O-O 6. d3 d6 7. Bg5 Bxc3 8. bxc3 h6 9. Bh4 a6 10. Bxc6 bxc6 11. d4 g5 12. Nxg5 hxg5 13. Bxg5 Qe7 14. f4 Qe6 15. f5 Qe7 16. Qe1 exd4 17. Rf4 Qe5 18. Qg3 1-0 Just to add that a lot of programs play the "suicidal" move g5? like in the game Spike against Junior. And Spike won more of this games with this position that way. An average human player does not have to calculate, he even feels that pushing the pawn shield of the King is much too dangerous here. I think this is a general weakness in many chess programs. [Event "CEGT 4"] [Site "CEGT"] [Date "2005.05.13"] [Round "2.4"] [White "Shredder 9"] [Black "Glaurung 0.2.3"] [Result "0-1"] [ECO "B06"] [PlyCount "60"] [EventDate "2005.05.12"] 1. e4 g6 2. d4 Bg7 3. Nc3 d6 4. f4 c6 5. Nf3 Bg4 6. Be3 Qb6 7. Qd2 Nf6 8. O-O-O Qa5 9. Qe1 O-O 10. e5 Nd5 11. Nxd5 Qxd5 12. c4 Qe6 13. Qh4 f6 14. Rg1 Bxf3 15. gxf3 fxe5 16. fxe5 Rxf3 17. Bg5 dxe5 18. d5 cxd5 19. Bg2 e4 20. Bxf3 exf3 21. Rge1 Qb6 22. b3 Nc6 23. Rxd5 Qb4 24. Re3 Rf8 25. Qf2 e6 26. Rd7 Qc5 27. Rxg7+ Kxg7 28. Qb2+ Kg8 29. Bh6 Ne5 30. Rxe5 Qg1+ 0-1 http://www.husvankempen.de/nunn/downloads.htm As a lot of testers in AEGT and CEGT and time controls are identical (40/40 adapted to 2 Ghz P4 CPU) I updated the combined rating list. The database contains now almost 40 000 games at this level. http://www.husvankempen.de/nunn/rating.dat As always...do not take seriously ratings with less than 500 games per engine, look suspiciously at those with 1000 games. From all we know from CEGT we think we need 2000 games per engine to have really reliable values. Best Regards Heinz _________________
