Now, there are probably a ton of scandals and shocking developments that are inevitable when a large tournament like this is squeezed into two days. One thing that might have been avoidable was a bizarre game between two well-known Russian super-GMs.
In the video stream the players can be seen seated and waiting for the signal to start the game. They are obviously getting on very well when one of them (Ian Nepomniachtchi) can be seen moving his hand as if making moves and saying something, before cracking up in laughter. Then both players smile. When the rounds starts they both put their hand up to hide their grins and then move their knights around the board for a few moves until they are back at the starting position. Then they agree to a draw and an arbiter, which was watching, follows them when they walk away.
The arbiter interviewed the players and ruled that they should forfeit the match since they had prearranged the result (which I'd say is evident). The decision also references that the players must not bring the game of Chess to decrepitude with their actions.
I don't know if the arbiter could impose harsher punishments on the spot. Probably the disciplinary commission could.

Thinking of this incident, which is especially unusual in that it is in public (no smoke filled room needed) and they are literally giggling about it, the question that occurs to me is: Could this ever happen in Go?
Maybe it couldn't. Draws and draw offers is something that is different which may lower the threshold for the players to fix their game. Another thing is that this is a very large Swiss tournament with endlessly many rounds, that is common in Chess but not in Go. Maybe what you do in the middle of a 21 round tournament really doesn't seem to matter, even for someone contenting for a world championship title.
Maybe this could happen in Go. I have a health dose of Go snobbery and can't imagine how
