"Chess Is in Chaos Over Suspicion That a Player Cheated Against Magnus Carlsen"

 From The Wall Street Journal, September 8:

When the world champion withdrew from a major tournament after a stunning loss, it ignited suspicions of foul play. Hans Moke Niemann, his opponent, denied any wrongdoing. Chaos ensued.

Magnus Carlsen’s 53-game unbeaten streak had been over for only a few hours when the reigning chess world champion made a move that indicated something was off.

Carlsen had lost to 19-year-old American grandmaster Hans Moke Niemann at a prestigious tournament in St. Louis called the Sinquefield Cup when he announced, without explanation, that he was withdrawing from the whole event. The chess world was quick to read the tea leaves.

“I think Magnus believes that Hans probably is cheating,” said Hikaru Nakamura, an American grandmaster ranked No. 6 in the world, who added that the allegation remains “unproven.”

What has followed since Carlsen’s exit is a supercharged scandal that is short on details and long on breathless speculation. Carlsen, the world’s top player, has said nothing publicly other than a not-so-cryptic tweet in which famous soccer manager Jose Mourinho protests the result of a match by saying: “If I speak, I am in big trouble.” A spokesperson for Carlsen didn’t respond to a request for comment. Niemann forcefully denied ever cheating at over-the-board chess—while also conceding that he has previously cheated online.

Tournament organizers, meanwhile, instituted additional fair play protocols. But their security checks, including game screening of Niemann’s play by one of the world’s leading chess detectives, the University at Buffalo’s Kenneth Regan, haven’t found anything untoward.

The controversy gained such momentum that top grandmasters are taking sides. In one camp are the chess professionals legitimizing the allegation and jumping to Carlsen’s defense. In the other are the players who view the whole thing as a witch hunt.

One competitor, Wesley So, said he could hardly sleep because of the drama. Another, Ian Nepomniachtchi, said that stamping out cheating completely would require extraordinary measures—such as “playing naked in a locked room” to make sure no one was carrying any secret buzzers or other devices.....
