Middlegame Uncertainty

This is a game I started on ICC correspondence before I discovered Chess.com (chess.com -> your interface is divine). It just finished, and I've been dying to ask about it. The main issue I had in this game was a few of the middlegame moves. I felt I didn't have a good plan at times, particularly around moves 28 through 34. The game felt very even and balanced throughout. In the end, I won, but I'm not really sure I was winning until I found a subtle tactic that presented itself.

Let me know what you think and where you believe I could improve. Note, I have not run this through an engine to check it yet, and I've annotated as many of my thoughts as I could recall them.

At move 14 or so, I wonder if you could have maybe carried out a different plan; compare it to move 23 - White has the two bishops and a lot of pressure; I think White should have been able to take advantage of that (maybe 23. Na3 to b5).

What do you think of something like 14. ... Nh5?  Intending f5, your kindside pieces can come alive and you can maybe create some holes in White's kingside.  I'm even tempted to suggest a Na5, heading to b3 and maybe taking the two bishops.

Just some quick thoughts!  Nice game.

Around move 28, one plan might be to put the queen on the E-file and try to break through that way.  After you play Qe2 he'll likely trade queens, getting your rook to e2 and threatening his position from behind.

Although, I'm not sure that plan is the best if you want to win.  You have opposite colored bishops, so if you trade too much material it becomes a theoretical draw.  I think White had a slightly better position - his bishop isn't blocked, and his knight can get to his outposts a lot easier than yours can (and if he can get his to d5 and you get yours to c3, his is a lot better anyway.)

Move 37 - why doesn't he play f4, like you mentioned he might do earlier?  You've only defended with your queen, meaning he could get queen and pawn for bishop and rook, which is surely in his favor.

Ooo.. thanks for pointing that out. He had a brutal tactic there, but didn't find it.

I like the aggressive Nh5! Thanks for pointing it out!
