Due to starting a tournament to which a lot of really high-rated players (1900-2300) decided to join I have been loosing a lot of games lately and playing against an opponent of the same level was very relieving. I had a feeling of controlling most of it after just a couple of moves. What do you think of my play? What could I have done better?

Edit: Just reread my title, seems a bit hybris; "but HOW could I have played better?" would be a better formulation.

were you not concerned of the fork 13... Nc7?

good play. The early cramping of your pawns might have not been such a good move since it relieves pressure. Have you run it through computer analysis yet?

Davie85: Yes I was very concerned of that, which I also wrote in my annotation. However after 13. Nxc7+ Ke7 14. Nxa8 I have the threat of 14... Bh3! after which white would be in very deep trouble. One possible continuation would be 15. g3 Nd4 16. Qd1 Bg4 and white will have to play very good to be able to defend himself.

To promotedpawn: No, I won't be able to for another 6 days :(. But I certainly will.

Actually, after 13.Nc7+,what I see is ...Kd8, 14.  Nxa8? Nd4 is quite strong, then 15...Bh3 once the white queen moves

i would maby have moved 7.Kh1 as white to open the f or g file for attack, but thats me, and it's not very stable, if he takes on the pawn and opens the g file, i'm not really wure wheather he should have taken the pawn on move six or do what i thought about... maby niether...

5. f5??, if white played 6. Ng5 you would of been in a world of hurt. (I think Bg4 is the book line)

Ouch, good find bondiggity, can't believe I missed that.

Good game. you missed 19...Rxf4! since 20.gxf4 Bf3+ 21. Kg1 Rg8#.
