Great OTB game

I just played in my second OTB tournament in Rochester, NY on Saturday.  I'm provisionally rated 709, and in the first round I got the black pieces against a 1968.  I'm very proud of the way I played this game, minus two errors that ended up costing me the game.  Any suggestions are appreciated.

I couldn't figure out how to put comments in the game, so here's a few I have.

6...Bb7??  Pointless move, I ended up moving right back to c8 later.

17...Bd6??  Loses the game.  17...Qe7 is the good move at this point.

I had Rybka play both sides after 17...Qe7, and it ended up drawing by repetition around move 23.

nice game

yea idk why you resinged.  according to rybka, u were only -0.44 with ..Kf8

There is no chance for Black after 18...Kf8; 19.Bh7

16...Qg5+ seems extremely winning for you

Which is clearly indicated by the three dots as is convention.
