World chess champion Magnus Carlsen confirms he quit match against Hans Niemann over cheating scandal: "I believe that Niemann has cheated more"

Norwegian world chess champion Magnus Carlsen has confirmed that he pulled out of a recent tournament and quit during a match against Hans Niemann because he believes the 19-year-old American has been cheating.

Carlsen last week sent shockwaves across the chess world when he resigned after just one move during a match against Niemann in the Julius Baer Generation Cup. The move came just one week after the 31-year-old grandmaster withdrew from the Sinquefield Cup in the U.S. after losing to Niemann, who has admitted to cheating in online games in the past. Many speculated Carlsen's abrupt withdrawal was connected to the ongoing alleged cheating scandal, although he had initially refused to say so.

On Monday, Carlsen confirmed in a statement that he made the "unprecedented" decisions because he believed that Niemann's cheating goes beyond what the American has already admitted to.
