Happy new year to all!

After my win against IM Alonso Rosell (http://www.chess.com/article/view/calling-an-audible) in round 8, I faced the young Bulgarin IM, Kiprian Berbatov, in the last round.

In the morning round, I didn't play particularly well, but I managed to win thanks to some gifts from my opponent. In the evening round, the 2-game a day schedule seemed to have taken a toll on my opponent, who made some pretty poor decision in the opening. I then should have landed a knockout blow, but in my haste to win in a beautiful fashion, I threw everything away and had to win it all over again ...
