A Good Chess Cheater Might Never Be Caught

Ever since he beat the greatest chess player who ever lived, Hans Niemann has been called a cheat. The 19-year-old's surprising victory over Magnus Carlsen in St. Louis on September 4 led to accusations that he'd been taking cues from a chess-playing AI, or chess "engine." Niemann later admitted to having done just that on two occasions--both times when he was even younger, and while he was playing chess online. But he'd beaten Carlsen fairly, he insisted. For weeks now, chess experts have been trying to assess that claim, posting what they've found on social media.
