Go up one level in this thread


I'm busy with a "theoritical discussion" with a friend, already played some
dozen blitz games and let some commercial program run overnight on the position.
I didn't find one game in my database for this position (very unbalanced) fritz
says -+, junior says +- :))

[d]r3kb1r/1bq2pR1/p4P2/3Pp2p/1p6/6QB/PPP4P/2KR4 b kq - 0 23


this pos come from this moves :

[Event "?"]
[Site "?"]
[Date "2003.??.??"]
[Round "?"]
[White "x"]
[Black "y"]
[Result "*"]
[ECO "B99"]

1. e4 c5 2. Nf3 d6 3. d4 cxd4 4. Nxd4 Nf6 5. Nc3 a6 6. Bg5 e6 7. f4 Be7 8. Qf3
Qc7 9. O-O-O Nbd7 10. g4 b5 11. Bxf6 Nxf6 12. g5 Nd7 13. f5 Nc5 14. f6 gxf6 15.
gxf6 Bf8 16. Rg1 h5 17. Rg7 b4 18. Nd5 exd5 19. exd5 Nd7 20. Nc6 Bb7 21. Bh3
Ne5 22. Nxe5 dxe5 23. Qg3 *

                        2)23...h4 24.Qg5 Qd6 25.Be6 ...
