OK, some more facts about this problem:
I'm currently playing a game at 10 min/move fixed between MChess 7 and
Rebel 8 on my P6-200, 60 MB hash each.
Rebel left the book at move 13. MChess left the book at move 31!
And that happened only because Rebel moved away from 31.Nd4 (which it
considered from 0:00 on) close to the 10:00 mark; had it played Nd4,
MChess would have stayed in book for another 3 moves! I.e., in a normal
tournament game, Rebel would never have reached the point where it moved
away from Nd4.
So this _could_ mean it's an anti-Rebel8-line (though the eval out of
book in the "31.Nd4"-line was only +0,68 by MChess).
here's the game:
[Event "Long time control tournament A"]
[Site "SHEP'S SERVER"]
[Round "2"]
[White "Rebel 8.0"]
[Black "M-CHESS 7.0"]
[Score "*"]
1. e4 c6 2. d4 d5 3. e5 c5 4. dxc5 Nc6 5. Bb5 e6 6. Be3 Nge7 7. Nf3 Nf5
8. Bd4 Nfxd4 9. Qxd4 Qa5+ 10. Nc3 Qxb5 11. Nxb5 Nxd4 12. Nbxd4 Bxc5
13. O-O {Rebel out of book at -0,16} Bd7 14. Rfd1 O-O 15. Nb3 Be7 16. c4
Bc6
17. Nfd4 Rac8 18. Na5 Bd7 19. cxd5 exd5 20. Rac1 Rxc1 21. Rxc1 Rc8
22. Rxc8+ Bxc8 23. Nab3 a6 24. f4 Bd8 25. Nc5 g6 26. b4 Kf8 27. Kf2 Ke7
28. Ke3 f6 29. Ne2 b6 30. Nd3 Bf5 31. a4 Kf7 {MChess out of book at
+0,17}
However, I've recently posted a game Comet A.80 - Fritz 5 to r.g.c.c.
where
Comet came out of book at +3,15. I called this a "Fritz-killer line",
but
Comet's author Ulrich Tuerke told me the opening came from a book on the
Slav Gambit and was automatically compiled into the opening book.
So there's always a possibility something is _not_ a killer or anti-XYZ
line...
