Chess grandmaster accused of using sex toy to cheat, win against Magnus Carlsen

There is a lot going on in the main controversy of whether Hans cheated, whether Magnus's dropping out of the tournament was correct, etc.

The "anal beads" thing was originally a joke made by another prominent chess streamer, not intended to be taken seriously as a potential cheating method. There are a lot of possible cheating methods being discussed but "anal beads" was never a serious accusation.
