Input: Story highlights Gaioz Nigalidze is banned from the Dubai Open Chess Tournament 
  
 Officials say he frequented the bathroom, where his phone was hidden in toilet paper 
  
 That phone had a chess analysis application open, officials say 
  
 (CNN) Sometimes the best ideas come from the bathroom. But Gaioz Nigalidze's ideas from the loo were a little too good. 
  
 The Georgian chess grandmaster has been banned from the Dubai Open Chess Tournament after officials discovered he was darting to the toilet to consult his smartphone, which was logged onto a chess analysis app, the Dubai Chess and Culture Club said. 
  
 Nigalidze's opponent, Tigran Petrosian of Armenia, grew suspicious when Nigalidze kept bolting to the restroom. 
  
 "The Armenian noticed the Georgian was oddly frequenting the toilet after each move during a crucial part of the game," the Dubai Chess and Culture Club said. 
  
 When officials first checked Nigalidze, they didn't find any device on him, the club said. But after looking into the bathroom stall he visited, they found the smartphone hidden in toilet paper.

 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. ||||| Image copyright Getty Images Image caption Mobile phones have been banned from chess tournaments for some time 
  
 A chess grandmaster has been expelled from an international tournament after he was discovered using a smartphone in the toilet to check his moves. 
  
 Gaioz Nigalidze could face a three-year ban if the complaint against him is upheld. 
  
 The reigning Georgian national champion was playing Armenian Tigran Petrosian in the sixth round at the Dubai Open. 
  
 Petrosian alerted officials after noticing that his opponent was visiting the bathroom at regular intervals. 
  
 Nigalidze was apparently using the same cubicle each time for ten minutes or more, arousing his rival's suspicions. 
  
 When the player emerged from the toilet, officials discovered a smartphone wrapped in toilet tissue and buried in the bin. 
  
 "He denied it was his, but it was logged into his Facebook page and there was a chess program running on it, showing his positions," the tournament director Yahya Mohamed Saleh told the BBC from Dubai. 
  
 The first prize up for grabs at the competition was $12,000 (£8,000). 
  
 'Very talented' 
  
 Gaioz Nigalidze did not respond to an email request for comment. 
  
 The Georgian Chess Federation called the incident "very bad," but said it was waiting to hear the player's side of the story before passing judgement. 
  
 "He is very talented," Sofiya Nikoladze told the BBC.

 "He's a very nice young man and I would never have thought he could do such a thing," she said of the 26 year old, who is ranked 400th in the world. . 
  
 It is the first case of a grandmaster being referred to the International Chess Federation (FIDE) since it established an Anti-Cheating Commission last year. 
  
 Describing the problem in chess as "high-tech doping," officials say they have increased their efforts to stamp it out. 
  
 As computers have become more discreet and more powerful, FIDE has begun deploying metal detectors, blocking devices and carrying out random inspections of players to prevent their use at competitions. 
  
 In 2008, before smartphones became widespread, an Iranian player was banned from the Dubai Open for taking tips via text message. 
  
 Today, cheating is relatively rare at the top level but lesser players have been known to hide electronic devices in their socks and shoes, and even inside their ears. 
  
 As a result, arbiters are now permitted to search competitors. Failure to comply can lead to expulsion.

 Bad move 
  
 "The problem [of electronic cheating] has increased in the past three or four years, so we've made special efforts to combat it," Yuri Garrett, secretary of the Anti-Cheating Commission explains. 
  
 He says a poor cheat who manages to consult a computer and then makes too many strong moves will easily be spotted; a more intelligent fraudster who only seeks outside help a few times might evade automatic detection. 
  
 A formal complaint has been sent to the anti-cheating commission at FIDE, which is now investigating. The commission then refers the case to an ethics committee for a ruling. 
  
 Should it confirm that Gaioz Nigalidze was using a computer to help his game in Dubai, the Georgian will be penalised with a lengthy ban from chess. 
  
 That would make the decision to cheat the worst move of his career. |||||
Output:
Chess has a case of "high-tech doping," the BBC reports. Georgia's national chess champion, Gaioz Nigalidze, visited the same bathroom stall enough during the Dubai Open on Saturday that his opponent, Armenian Tigran Petrosian, became suspicious. "Nigalidze would promptly reply to my moves and then literally run to the toilet," he tells the Telegraph. Officials investigated and the BBC reports they found a phone covered in toilet paper in a trash bin. "He denied it was his, but it was logged into his Facebook page and there was a chess program running on it, showing his positions," the tournament director says. Nigalidze, ranked 400th in the world, was booted from the competition and is the first grandmaster to be referred to the World Chess Federation's (FIDE) Anti-Cheating Commission, set up last year. At stake in the tournament is a $12,000 prize. The Georgian Chess Federation says the incident was "very bad," but it plans to hear from the 26-year-old before discussing retribution. Cheating with electronic devices "has increased in the past three or four years, so we've made special efforts to combat it," the secretary of the Anti-Cheating Commission says. FIDE officials are able to search tournament participants, while metal detectors and blocking devices are also used. After an investigation, the commission will pass the case to an ethics committee, which will decide Nigalidze's fate. The tournament's chief arbiter tells CNN that guilty parties are handed a three-year ban from sanctioned tournaments, while repeat offenders face a 15-year ban. On Twitter, former world title contender Nigel Short suggested Nigalidze should face criminal charges for fraud. (Meet the youngest US grandmaster ever.)
