At least for Veselin Topalov. Last year it was the month he lost the World Championship match to Viswanathan Anand, this year it is his exit from the Candidates matches at the hands of Gata Kamsky.
But no one could accuse Topalov of not giving his all. Going into the final game needing a win to force the match into playoff games, he gained an edge in the middlegame, and a mistake by Kamsky on move 38 gave him a winning position. However on move 46 he moved his king into the open, and suddenly Kamsky had enough to draw the game. For the next dozen move Topalov kept pushing for a win, but Kamsky continued to defend, and Topalov abandoned the game as a draw.
So the unfancied Kamsky goes through to the next round and a match with Gelfand. The other two semi finalists are yet to be decided, with the playoff games happening as I type this.
