A top chess player has offered to play in the nude amid allegations of cheating.
Hans Niemann made the pledge after his victory over world champion Magnus Carlsen in the Sinquefield Cup as he faced claims of skulduggery after his Norwegian opponent withdrew from the tournament.
Niemann, 19, confessed that he played with computer help when he was younger, but is willing to play in the buff to prove that he is not a cheat.
He said: "If they want me to strip fully naked I will do it. I don't care. Because I know I am clean. You want me to play in a closed box with zero electronic transmission, I don't care."
Niemann confessed that he had cheated in games at the age of 12 but has put his bad behaviour behind him.
He said: "I have never cheated in an over-the-board game. And other than when I was 12 years old I have never cheated in a tournament with prize money."
