Here's the analysis for my game with OlimarFan. I don't have time to do what N9NE did with the colors, sorry.
The obvious blunder was 20. Rd3. I don't even know why I made that move. I had first considered it, then discarded it because of the fork. Then sometime later I come back to make the move, and forgot about that and made it anyway! wtf was I thinking.
The other inaccuracies I'll have to sit down and look at myself so I can understand them. Besides that, there were a lot of times when my score would drop a couple tenths of a pawn, so I'm guessing I had a lot of small chances to capitalize the weaknesses in blacks position, but I failed to do so. Good game
