The world of elite chess has been engulfed in a cheating scandal after a picture emerged of a top grandmaster sat on a toilet using a mobile phone during a tournament. Police are investigating after Igors Rausis, who has represented Latvia, Bangladesh and the Czech Republic, was caught 'red-handed' in France, the game's governing body Fide said. Phones are banned at chess tournaments because of chess software that can be used to suggest winning moves. Rausis, aged 58, had aroused suspicion by reaching the game's top echelon at an age most players decline in strength.
