Georgian chess champion and grandmaster Gaioz Nigalidze has been expelled from the Dubai Open Chess Tournament after he was caught cheating.
Nigalidze was caught sneaking to the toilet to check moves on his mobile phone during a match on April 12.
Nigalidze's opponent in the sixth round of the tournament -- Armenia's Tigran L. Petrosian -- lodged a complaint after the two-time Georgian national champion kept getting up to go to the bathroom between moves.
Tournament organizers found Nigalidze had stored a mobile phone in a cubicle, covered in toilet paper.
The tournament's chief arbiter, Abdul Rahim, said he had reported the incident to International Chess Federation.
If found guilty, Rahim said, Nigalidze would be suspended from all sanctioned tournaments for three years and up to 15 years in case of a repeat offence.
