Grandmaster caught cheating at chess in a lavatory

Bad move: Grandmaster caught cheating at chess in a lavatory

A disgraced chess Grandmaster faces a 15-year ban from the game after being caught pretending to be desperate for the loo so he could use a mobile phone to cheat.
Georgian champion Gaioz Nigalidze was expelled from the Dubai Open on Saturday after his opponent Tigran Petrosian, became suspicious about the amount of times he nipped to the lavatory.
A complaint followed and Nigalidze was challenged. Tournament organisers then found Nigalidze had stored a mobile phone in a cubicle, behind the pan and covered in toilet paper.
The device was found to be logged into Nigalidze's social networking account and had one of his games being analysed by a smartphone chess app.

After Saturday's match, Armenian Grandmaster Petrosian said: "Nigalidze would promptly reply to my moves and then literally run to the toilet.
"I noticed that he would always visit the same toilet partition, which was strange, since two other partitions weren't occupied.

"I informed the chief arbiter about my growing suspicions and asked him to keep an eye on Gaioz.
"After my opponent left the very toilet partition yet another time, the arbiters entered it.

"What they found was the mobile phone with headphones; the device was hidden behind the pan and covered with toilet paper."
The tournament's organisers announced their decision to expel Nigalidze on Sunday morning on their Facebook page.

It said: "A cheating incident was found during round 6 by Georgian GM Gaioz Nigalidze ... bravo to Chief Arbiter Mahdi Abdul Rahim for taking the complaint seriously and raising it to the Tournament Director.
"An electronic device was found in the toilet ... Full story with pictures to be published soon.”
British former world title contender Nigel Short said Nigalidze "should be stripped of his GM title and banned immediately" and called for FIDE, the game's governing body, to tighten up rules.

The incident follows a warning from British GM Daniel Gormally last month.
He refused to name any names but told the Telegraph he was suspicious about "improvement" some players have shown.
Allegations of cheating are rare at the top level of chess.
However, in July 2013 Bulgarian player Borislav Ivanov was suspended from playing for four months by his national federation.
It had been found most of his moves matched those of the leading computer chess analysis programs.
Two years earlier the French chess federation suspended three players, including the national team captain, after it was alleged they used mobile text messages, a remote chess computer and coded signals to beat the opposition at the 2010 Chess Olympiad.
