Good Positional Chess
I'm very happy with this game. I played good positional chess, slowly accumulated advantages. I think I avoided any big blunders or at least if I missed something my opponent did too.
I kept my position solid while collecting weaknesses from white. White did a good job of defending for a while but as pieces go traded it became impossible. Then some bad moves at the end finished it.
