Hard to find much to say here... you already ran it through an engine, so it's not like we're going to find some tactical move you missed. The game was primarily tactical.
You did a pretty good job except for that blunder at the end, I think. Although I don't think I would have played 9 a4 either, because it does sort of create a weakness down the a5-e1 diagonal. Your opponent came up a little short in trying to take advantage of it.
Hi people. This is Haiku575, a recent addition to this website. . . I was wondering if anyone would like to go over this game with me? Both of us played fairly well, except for a few idiotic moves every now and then which made my computer die laughing at us.
Anyway, here it is. I didn't post all of it (I lost after I panicked), but the interesting bits are here.
