As given in phenomenal detail at Isle of Man Online here, GM Nigel Short walked out of the 12th Monarch Assurance Isle of Man Chess Tournament. After his opponent didn't show up, he notched the win but was then told he would be paired with another opponent. I can understand re-pairing someone, but after they had sat at the board for an hour waiting for someone else?! What kind of rule is that? More details and the conclusion are now posted at ChessBase here.
