Earlier quoted context omitted.
Magnus' evidence of "it didn't seem like he was thinking very hard during critical junctures" is the nail in the coffin for me. If he has a history of stealing cars AND his new car is hot wired? Possible it's legal? Sure. Let's not twist our hands about a grand theft auto charge, however.
I don’t think you can call the opinion of the famous player who lost about how hard he thought his opponent was thinking during the game evidence without twisting the meaning of the word past the breaking point.
we can't accept Magnus's testimony on this point, but we can understand that Magnus can consider it himself to be evidence, and he's simply telling us that's what he's doing.
I also think Magnus believes he has additional information about the extent of Hans's cheating, and that's what he can't share without Hans's permission, probably Hans's logs of his online activity that chess.com has, or something like that.
