Central California Open u-1800

Wow I didnt know this forum existed! I had posted this in the game showcase but analysis is definitely what I wanted. These are games from a tournament I played in fresno last year, I came in 4th place out of around 20 players in the 1600-1800 range (and a few who were unofficially above 1800). I think I made most of my mistakes in the opening so comments there would also be helpful, rather than just the middlegame. I played this while I was going through a lot of personal stuff, so Id not be surprised if there were blatant errors in a few of my games.

Here I played against the guy who went on to win the tournament. Also I copied and pasted this from a blog post I made, sorry if Im talking down at you guys in my annotation.
