A King's Indian Attack.
This is my game one win, which was my only win! I won the first, was winning but threw away the second, and never recovered mentally, and threw away rds 3 and 4. I withdrew before round 5 and went home to hang out with the kids.
I will enter game 2 on another thread. I lost that one, but I think it is probably the more interesting of the two decent games I had.
In this game, I think my opponent was surprised by 23. Re5, by 25. a5, and by 46. b3, all of which are related in style somewhat.
Edit: I forgot to add- the time control for the first two rounds was G/75, and we made the endgame moves relatively quickly.
