Viswanathan "Vishy" Anand (2787, IND) retained the World Championship title by successfully defending it against challenger Veselin Topalov (2805, BUL). I remember watching the 12th game online last night. Anand and Topalov were on an equal score. The opening was the Queen's Gambit Declined and the middlegame looked very drawish to me. I went to sleep fully expecting that the game was drawn and the World Championship would be taken into extra tie-break games, but I was surprised today to learn that Anand had won. He had played ambitiously against Topalov's passive play and was able to break through.
Here are the final results (click the image to enlarge):
I will give an overview of all the games shortly. Watch my 2010 Topalov-Anand World Chess Championship page for any updates. Currently, I have discussed 6 of the games from the WCC, and I will add the other 6 very soon.
