Magnus Carlsen, the reigning World Chess Champion, suddenly resigned after making just a single move Monday during his widely anticipated rematch against Hans Niemann, whom Carlsen may have cheated in a game earlier this month.

The home of PSV football is where Magnus Carlsen of Norway will play in the chess tournament.
During a preliminary match for the Julius Baer Generation Cup, which Carlsen and Niemann played online using the Chess 24 platform and Microsoft Teams, Carlsen suddenly resigned and turned his webcams off.
The announcement of the resignation took Peter and Tania by surprise and they noted that it was a very big statement.
Both Carlsen and Niemann showed up at their scheduled matches on Monday, but neither commented on the brief match or resignation.
It was the first withdrawal in Carlsen's career after he lost to 19-year-old Niemann in the third round of the Sinquefield Cup. The first to beat Carlsen in more than two years was the lowest ranked player. Carlsen, who won his fourth World Chess Championship title in April, did not comment on why he withdrew from the tournament after losing to a lower ranked 19-year-old. Carlsen's comments were seen as accusations of cheating. The tournament strengthened its security measures and even searched Niemann before his match, but there was no proof. After an earlier interview in which he admitted to using computer assistance to win online games when he was younger, he was removed from Chess.com, the largest online chess platform.
