Back Rank Weaknesses

Here is a game I played this June at a local tournament. There were four rounds of games and I ended up tied for second with three wins and one loss. This was my only loss of the tournament. My opponent was an FM of rating 2238 who I have seen at many other tournaments in the area, but I have never played against him. Opening preparation against any master can be crucial in deciding the game, and here one bad opening move almost cost me the game. Also note the back row weaknesses that both players had, which leads to some interesting play. Enjoy!
