Vandoeuvre Open 2007 controversy
In the 4th edition of the Vandoeuvre Open chess tournament that he was attending, Oleg Krivonosov first accused Anna Rudolf of using the chess program Fritz, then changed the accusation to using Rybka. Gathering support from two other participants, Krivonosov claimed that Anna Rudolf, who had been playing very well and had beaten the top seed Christian Bauer, was using a lip balm in her bag as a transmitter to receive the correct moves when she used the bathroom. The accusations, which were without any material evidence, did not prevent Anna Rudolf from finishing the tournament with a high enough score to obtain her IM and WGM norms. Krivonosov is considered by many in the Chess community to be a bad sport and used the accusations to upset Anna Rudolf with the intent to reduce her performance to his own advantage. He has never apologized to Rudolf for his behavior.
