Hi, Thanks for showing the game. Around move 10, although you have the bishop (to his knight) you are a pawn down. So I guess you came out of the opening a little down.
I would not have traded queens when you did. Your're a pawn down so as the material gets taken off the board there's a danger that you slip into a lost endgame. After 13. cd: you have a central pawn but it is weak and isolated. At this point it's going to hard to save the game. Even if you manage to swap the d pawn for his e pawn you are left facing a 3:2 pawn majority on the queenside. I think that it is possible that the reason you overlooked subsequent attacks on your d pawn is because you saw it as a strength (a central pawn) rather than a weakness. Instead of 12. ... Qd6 I think I would play 12. ... Bd7 or, more likely, 12. ... O-O.
I am not very comfortable with the black pieces, and I think you can see it in this game.� I would say that over the total time I've spent playing chess since I was around 15 (I'm 28 now) I've probably played the black pieces 5% of the time.� I'm of course working on that now, however I'm posting this game for a little help.
While I was playing this game, I felt around move 17 that I had made a mistake somewhere b/c white's knight seemed to have some really nice squares.� I tried to stop that, and my game just fell apart.� On the bright side, I'm posting this game here for maybe a little analysis from you higher rated players.� Any comments you might have will definitely be read for full appreciation.
