I'm not sure why wasn't that blatantly obvious until today. Chess is an extremely unsuitable sport for online because you are 100% free to use the strongest computers on it without 100% no cheat protection at all. It should be ..100% restricted to person-to-person tournaments for keeping score.

The tournament Carlsen withdrew from today isn't an online event. All the games are played in person at the St. Louis Chess Club.

How was Hans able to cheat? Seriously curios.

Hmmm I wonder what this thread is called

It's pretty easy to detect the blatent cheaters who just copy moves from the top engines: you just run the engines on the game and compare the moves between the player and engine: a close enough match is certainly cheating. More sophisticated cheaters who actually know the game well themselves are harder to catch.
