Magnus Carlsen exits the match without explanation amid an apparent feud with fellow grandmaster Hans Niemann

The pair were playing in the Julius Baer Generation Cup when Carlsen turned off his screen and left the match without explanation – the latest twist in an apparent feud between the two players.

“We’ll try to get an update on that,” commented Tania Sachdev said in a live broadcast of the match on chess24. “Magnus Carlsen just quit – got up and left, turned off his camera and that’s all we know for now.”

CNN contacted Carlsen’s rep for comment, but received no response.

Earlier this month, the Norwegian retired from the Sinquefield Cup in Saint Louis after his surprise loss to American star Niemann – the first time in his career that he has retired from a tournament, according to chess24.

Carlsen further confirmed his withdrawal Twitter, Posting: “I’ve retired from the tournament. I’ve always enjoyed playing @STLChessClub and hope to return in the future.” Carlsen’s tweet also included a well-known video of football manager Jose Mourinho saying, “If I speak, I’m in big trouble.”
Another grandmaster, Hikaru Nakamura, said Carlsen was “suspicious” about Niemann’s behavior, and days after the Sinquefield Cup match, Niemann publicly responded to allegations that he cheated earlier in his chess career.

The 19-year-old admitted to cheating at ages 12 and 16, but said in an interview with the St. Louis Chess Club that he had never cheated at over-the-board games.

“I tell my truth because I don’t want any misrepresentation,” said Niemann. “I’m proud of myself that I learned from that mistake and now I’ve given everything to chess. I’ve sacrificed everything for chess.”

The tension between Niemann and Carlsen has rocked the chess community. Niemann said he was removed from popular website after Carlsen’s tweet and that “the entire social media and chess world is completely attacking and undermining me.”

“To see my absolute hero (Carlsen) trying to aim, ruin my reputation, ruin my chess career and do it in such a frivolous way is really, really disappointing,” he added.

Neither Niemann nor responded to CNN’s request for comment.

in one expression On September 8, Chief Chess Officer Danny Rensch said the site had “shared detailed evidence with them [Niemann] regarding our decision, including information that contradicts his statements about the extent and seriousness of his fraud.”

Rensch continued, “We have asked Hans to provide an explanation and response in hopes of finding a solution where Hans can participate in again.”

Carlsen and Niemann played two more games against different opponents after Carlsen’s sudden retirement on Monday. After eight rounds, Carlsen is two points behind leader Arjun Erigaisi and Niemann is four points behind in the tournament standings.

“It looks like he (Carlsen) is clearly implying something, but until you catch someone there’s nothing you can do,” Anish Giri, who also competes in the Julius Baer Generation Cup, told chess24.

“It just looks very strange now. Sure, it all makes sense if Hans is said to be cheating and he doesn’t want to play against him, but if he doesn’t (cheats) then it’s really very wrong.

“Well I don’t know, we’ll have to see. Again, everyone is expecting some kind of big rabbit out of a hat with Magnus, but he just doesn’t want to play Hans it seems.”

Levon Aronian, who is also attending the tournament, said Niemann is “not the cleanest person when it comes to online chess” but added that “this is a problem that needs a solution”.
