The only thing that will happen to Hans is that he will lose his career and fade into oblivion. Alternatively, he will go the Lance Armstrong route, confess to everything with Oprah, and redeem himself as a decent chess player that streams professionally.
But this is a cry wolf situation - I would be surprised if there isn't some terms or condition that allows chess.com to ban known cheaters esp from a tourney with such a big prize.
That’s… not how the court system works.
It's my opinion that Hans Niemann cheats every chance he gets. Maybe my opinion is wrong but I have every right to it.
