Mimchi vs Freel

In this game, I was very confident, for some reason. I felt I had bypassed the "opening" and I now know how to play directly into the middlegame. What I mean is that I am already so familiar with these Catalan positions that I'm already looking to trade off DSB's, play e5, and thunk a knight on d6 or c5. My opponent reacted rather rashly with ...f5 (which is a useful defensive move but not so early in the game!), and I tore open the center. I still blundered back a piece (!) but my position was so completely winning that it didn't matter. However, I should focuse more on accuracy and not blundering in a completely winning position!
