A chess prodigy has been accused of using anal beads to cheat in matches.
Hans Niemann has been at the centre of a scandal after world champion Magnus Carlsen suggested that the 19-year-old used the beads to get communications from his coach after Niemann earned a shock victory against him.
Niemann has denied the allegations and revealed that he did cheat twice when he was younger but has always regretted it.
However, an investigation by the website Chess.com, has suggested that the American is likely to have cheated "much more often".
The site - which has banned Niemann over the allegations - said: "We have found Hans has likely cheated in more than 100 online chess games, including several prize money events. He was already 17 when he likely cheated. He was also streaming in 25 of these games."
Despite the claims, Chess.com admitted it has no proper evidence that Niemann cheated.
