The world of chess has been rocked by accusations of cheating made by the world’s top player, Magnus Carlsen, after he was beaten by a 19-year-old prodigy who admitted to cheating in the past while insisting he is now “clean”.
The Norwegian grandmaster Carlsen sent shockwaves around the sport when he quit a $500,000 tournament in St Louis less than 24 hours after his surprise defeat to the US player Hans Niemann.
