Oct-03-13  jerseybob: The opening is fascinating on both sides and I won't even try to judge good and bad, but white might have tried 18.exd4, with the idea of Be3,Nd2 etc. In the second half of the game, white just totally falls apart.
Oct-03-13  Wyatt Gwyon: One of the ugliest games I've seen in a while.
