How do you even cheat in chess? Artificial intelligence and Morse code

It's the story that has rocked chess and shown no sign of abating. The cheating scandal which has engulfed the sport, involving five-time world champion Magnus Carlsen, is all anyone is talking about. On Monday, Carlsen explicitly accused fellow grandmaster and rival Hans Niemann of cheating for the first time in a lengthy statement on Twitter. The accusation comes weeks after the Norwegian withdrew from the Sinquefield Cup in St. Louis, Missouri, on September 19 following his surprise defeat to the American. "When Niemann was invited last minute to the 2022 Sinquefield Cup, I strongly considered withdrawing prior to the event. I ultimately chose to play," Carlsen wrote.
