In a game between Shredder 7.04 and Chess Tiger 15 (ChessBase, style normal), 25 minutes per game, no pondering, P4-2400, both 96 MB-Hashtables Chess Tiger made a big tactical mistake: [Event "Wettkampf P4-2400, Blitz:25'"] [Site "?"] [Date "2003.04.14"] [Round "12"] [White "Chess Tiger 15.0"] [Black "Shredder 7.04"] [Result "0-1"] [ECO "A80"] [PlyCount "52"] 1. d4 f5 2. Nc3 d5 3. Bg5 Nf6 4. e3 e6 5. Nf3 Be7 6. Bd3 c5 7. dxc5 O-O 8. a3 Ne4 9. Bxe4 fxe4 10. Bxe7 Qxe7 11. Nd4 Nc6 12. Nb3 Qg5 13. O-O Ne5 14. Qe2 Nf3+ 15. Kh1 Rf6 16. gxf3 exf3 17. Rg1 Qh5 18. Rg5 Qxg5 19. Qf1 Qh5 20. Nd2 Rh6 21. Qg1 Rg6 22. Qf1 e5 23. Nxd5 Rg2 24. Nxf3 Bh3 25. Qd1 Rxf2 26. e4 Rf8 0-1 Have a look on Tigers move 14. Qe2?? (eval.: -0.12 at depth 13, expecting Bd7): Tiger has absolutely no idea of the further Nf3+!! which ends the game. It takes Tiger more than 3 minutes to evaluate Qe2 with -0.62 (at depth 15), expecting Nf3+, where -0.62 is still a very optimistic. And it takes nearly 7 minutes to find a slightly better move (Nb5, -0,44). I think this position could be helpful for further improvements of your impressive strong engine. Greetings Ulf
