You just can't make up this kind of stuff. From the New York Times:
"On a day in which no game was played, Silvio Danailov, the manager of Veselin Topalov of Bulgaria, sent a letter to the appeals committee of the match detailing what he said were an excessive number of bathroom breaks — more than 50 per game — by Vladimir Kramnik of Russia." For the rest of the saga read here.
Topalov showed up for game 5 (with complaints) but Kramnik's demand to have his bathroom unlocked was not met and thus he forfeited game 5. Topalov gains a point so the score is now Kramnik 3 and Topalov 2.
At least the match will now get the media coverage it has been missing! There's no such thing as bad publicity after all :-)
