Caro-Kann Debut!

Recently I played in the City of Dublin Chess Champioships(1600-200 section) and I have to say although I played ok it was my worst tournament performance ever. I got 2/6 but really .5/4 (I took a travelling BYE in round 1 and in round 5 my opponent didn't show up so I got a walkover). Here is my first game (from the second round of the tournament) which is the first time I've played the Caro-Kann OTB. I should have won but lost.
