Here is a game I found off of http://www.freechess.org/Ladder
It has already been annotated but I think they missed something.
I let my box analyze it for quite some time this morning and came up with what I
think may be a mate line, perhaps some of you would like to check it and verify.
Here is the game (the line I came up with will be below it).
[Event "1. Bundesliga"]
[Site "?"]
[Date "2001.??.??"]
[Round "?"]
[White "GM Nunn, J."]
[Black "Breder"]
[Result "1/2-1/2"]
[ECO "B12"]
[WhiteElo "2578"]
[BlackElo "2383"]
[Annotator "Breder (and *death)"]
[PlyCount "84"]
[EventDate "2001.??.??"]

like to analyse this intersting variation with me (with making own analyse
first) ?} 5. Qg4 h5 6. Qf4 (6. Qg3 h4 7. Qf4 Bxc5 8. Bd3 Qb6 9. Nh3 Qb4+ 10.

have here no compensation on the dark squers like in the game? Where is the
real difference?} 19. Bc2 {And now ?} 19... Nc4 (19... f6 20. Bf4) 20. Bf4 {

think I prefer the game line.}) 13. cxd4 Qxd4 14. O-O Qxe5 15. Qd1 Bd7 (15...
Kf8 {with advantage for black according to GM Dautov. What do you suggest for
white now and what is your estimation? *death: I'm not sure that there is much
difference between the game and Dautov's suggestion. I suppose the idea must
be to try to hide the king on g7, though it isn't clear to me why this move
must replace ...Bd7, or if there is some other plan for the black bishop. I
think the black king is going to come under fire wherever it goes. Black's
apparent lead in development and space are illusions; there are weaknesses on
the dark squares, and possibilities to get the white rooks into play. The only
advantage that black has is the two extra pawns -- which, of course, is a
significant factor.}) 16. Re1 Qf6 17. Nc3 17... O-O-O $2 {
Is is absolutly not a safe place for the black king.} 18. Be3 h4 19. Rc1 Kb8

hurry to retreat to g7? Was black worried about Bg5 and the capture on d8? How
about preventing that tactically, and maybe providing a kingside distraction
at the same time:} 20... g3 $1 21. Bf4+ (21. Bg5 $2 21... gxf2+) 21... Ka8 {
and though white's play is similar to the game, black is faster on the
kingside, and the queen may even prove to be more usefully placed.}) 21. Nb5 a6
