The day before game 11(updated).Oct 9,06:58PM
......At the same time not much informatio has been released about Kramnik's rest day. However, strange news was reported by Zhivko Ginchev. He said that Kramnik refused to make a doping test after game 9. The test has been requested by the chief of the medical commission Iana Belin, as reported by topsport.bg. "Everything here is very strange, but what can we do about it," commented Silvio Danailov for the Bulgarian newspaper Novinar. From the Bulgarian delegation also find it strange that such a test comes after the two consecutive victories of Topalov.

- Veselin, are you disappointed by today's result? This was your last White...
- The result is okay. Of course, I always want to win, but the result is appropriate. I did not have sufficient advantage to talk about winning seriously.

-Now you have to play your last game as Black...
-There is a rest day, and I will be preparing for the game 12. Right now I am happy to have passed the doping test easily! I'll start thinking about the final game tomorrow...
