This situation is really interesting to me, way, WAY back in the day I use to play tournament chess. Then life happened and I lost interest. This current situation has brought it back to my mind. I have never heard of these guys.
So after watching a bunch of videos.....learning about these two guys, I just gotta say. I don't suspect cheating. It just sounds like its way to difficult to get away with. Way to difficult.
What it sounds like to me is this current Champ, Magnus, is some sort of privileged prima donna. He started to get this ass handed to him, and he pitched a fit. The other guy...Hans, though he has a history of alleged cheating, just played a good game. Maybe his game was unusually good, but if we are to consider someone to be cheating for doing something unusually good....maybe we should look back at Bob Beamon, and see if he was cheating. How does a guy beat a long jump record by almost 2 feet when usually the record is broken by 1/2 inch at a time.
But I must stress, I don't know alot about the situation....only that the Magnus is very very good, and hangs out with stars and billionaires, and this other guy is very good, but somewhat strange. I can see Magnus pitching a fit because "someone" else put him in his place in an impressive way.
