Okay. I thought you were doing reasonably well until the last move or two.
I'm no expert like Smash and Spy but I believe cxd5 is often bad for white. The whole g3 and Bg2 felt like a bad idea to me since I have a cemented pawn on d5 and good control over e4. Meanwhile I got my white squared Bishop outside my pawnstructure, so it was like I was a piece up in the beginning.
After your 12:th move I have both my Bishops attacking your flank while yours aren't really doing much at the moment. I have a little more space to manouvre and I like my position a little better. It was hard for you to kick my Knight out of c4 since my pieces was so well coordinated on that flank while I could prevent your Knight from occupying the c5 square.
It felt like I had a little better grasp of the Queens gambit opening, maybe because it is the one I play with white all the time. Maybe I have an advantage if you play with winboard as most people do since I actually use a real life chessboard. I think it's easier to think that way. Let's play again if you want to.
