Chess’s cheating debate reignited: Magnus Carlsen resigns after one move in rematch with Hans Niemann

In a rematch of their round at the Sinquefield Cup earlier this month, which triggered one of the biggest recent debates in the sport of chess, reigning world champion Magnus Carlsen quit his preliminary matchup against Hans Niemann after just two moves in the Julius Baer Generation Cup on Monday.
The match took place virtually on Microsoft Teams, and was hosted chess24.com, on which Carlsen appeared via webcam, made one move, disappeared, and simply quit the match.

Another shocker as @MagnusCarlsen simply resigns on move 2 vs. @HansMokeNiemann! https://t.co/2fpx8lplTI#ChessChamps #JuliusBaerGenerationCup pic.twitter.com/5PO7kdZFOZ

Carlsen had turned heads earlier this month after he quit the $500,000 Sinquefield Cup following a defeat against Niemann, confirming his withdrawal posting a video of a famous quote football manager Jose Mourinho: “If I speak, I am in big trouble.”
Carlsen’s move sent the chess world speculating over whether or not Niemann had been cheating, a debate he will invariably reignite his latest resignation, which is seen as a protest.

I’ve withdrawn from the tournament. I’ve always enjoyed playing in the @STLChessClub, and hope to be back in the future https://t.co/YFSpl8er3u

At the time, Carlsen’s withdrawal was followed American Grandmaster and popular streamer Hikaru Nakamura’s claims that Niemann had likely cheated in their round, otherwise the Norwegian, who had never quit a major tournament like that before, would not have taken this step.

The silence of my critics clearly speaks for itself. If there was any real evidence, why not show it? @GMHikaru has continued to completely ignore my interview and is trying to sweep everything under the rug. Is anyone going to take accountability for the damage they’ve done?

Niemann had responded to the claims in an interview at the Sinquefield Cup saying he was willing to play naked to prove he was not cheating. He also came out on social media to publically address Nakamura.
No evidence of cheating has come out ever since Carlsen’s withdrawal, but chess.com, the world’s leading platform, banned Niemann following the controversy. Chess24, the second biggest platform in the world and the one being used on Monday, has allowed him to continue playing.
