I played Black. I'd played a number of 5-0 blitz games against this opponent, and gotten the impression that he over-relied on his Knights, so through my 7th move I was concerned with blocking them. I played 8. [...] b5. 9. [...] b4 and 10. [...] ♗xb4 because it was the best way I could see to get my King's Bishop into play and leave room for my King's Knight. I don't know what White was thinking with 11. ♕d2?, and 12. O-O-O?? just made a bad situation much worse for him. And then 14. ♕c1??? shortened the game at least a little.
By White's 3rd move we were already out of the MCO-13.
