Chess960 World Championship, Mainz 2004
The story as told on the Chesstigers.de page involved an error in castling O-O-O.
This position caused quite a stir in the fourth game of the Gerling Match between Levon Aronian and Peter Svidler. Levon Aronian took his rook on a8, jumped over the King and put it on d8. However, he forgot to take his King which had to be placed on c8 to fulfill all the requirements for a-side castling in Chess960. If he would have done that, the game would be over: Qa8 check and mate!
Peter Svidler stopped the clock and arbiter Sven Noppes came to see what was going on. Castling was possible, the mistake Aronian made was that he took his rook first, so he had to castle a-side.
Peter Svidler showed that he is a gentleman on the board and allowed Aronian to correct his move. The Armenian had to play Ra7 and kept the better position. However, after this faux-pas Aronian completely lost control and finally lost the game.
Was this just a mistake by the young Armenian, or did he try to win with a dirty trick? Aronian joked during the press conference : "Off course I wanted to cheat, just like in his game against The Baron in the computer match." Peter Svidler said: "I do not have a problem with Aronians mistake, and when you have only 40 seconds on the clock, like in this case, it is possible that you mix up the castling rules".
