> Magnus is not doing this in the best possible way.
You are assuming that his goal is to somehow uncover Hans cheating.
On the other hand if his goal is to highlight that in his opinion the security arrangements are not sufficient to be able to tell if an opponent is cheating or not, then he is doing that just right.
He spoke up and the competition in question introduced anti-cheating measures right the next day. That means there were things they could have been doing but were not before.
> Magnus should act and use his connections in the Chess world to catch him cheating.
How do you propose that could happen? Life is not a TV show with Perry Mason moments.
People have been caught cheating in the past.
Chess cheating is not black magic.
Chess engines are an integral part of the Chess world now, players a training with them, to analyze and prepare. I would not be surprised if many players tried to "enhance" their rating online with such an engine.
Chess.com probably has stats about this behavior.
My gut feeling is that online cheating is very common, and thus, saying that someone was caught cheating online is not a very strong proof that he also did it over the board.
