Chess Grandmaster Accused Of Cheating Has Butt Scanned Before Game

Teenage U.S. chess grandmaster Hans Niemann appeared to receive a more thorough security check than other players on his arrival at the U.S. Chess Championships in St. Louis this week.

A St. Louis Chess Club livestream showed Niemann, 19, being asked to turn around so the security wand could be waved over his buttocks as he entered the competition arena. But the two players before Niemann and the one after him were only scanned on their fronts.

The moment went viral because Niemann recently faced unsubstantiated rumors ― which he has denied ― that he used wirelessly-controlled vibrating anal beads or a prostate massager to receive messages from his coach about the winning moves for a stunning victory over world champion and Norwegian grandmaster Magnus Carlsen.

Niemann has admitted to cheating twice in his career, when he was 12 and 16, but denies all the other allegations — and has even offered to play in the buff to prove them wrong.

Niemann won his first pairing round in the U.S. championship against 15-year-old Christopher Yoo on Wednesday.

“This entire thing started with me saying chess speaks for itself and I think this game spoke for itself and showed the chess player that I am,” he told reporters. “It also showed I’m not going to back down and I’m going to play my best chess here regardless of the pressure.”
