I suck at chess, but there is something very strange about this whole story. There are a lot of vague accusations of "cheating" but I can't find anything, in any of these stories, that says SPECIFICALLY what Niemannn actually did that constitutes "cheating".
The only "evidence" seems to be nothing more than "He won a game that we think he shouldn't have won, therefore, he surely must be cheating." Seems very flimsy to me. What am I missing?
To my view the burden for what constitutes a successful accusation of cheating is pretty high. Normally I'm accustomed to the act of cheating being something done during a game/match/competition, not something done prior to it, unless it's literally either 1) equipment related, or 2) involves someone in the opponent's camp feeding one information, or feeding bad information to the opponent.
The only way I see to tamper with equipment in chess is to do something that causes discomfort to the opposing player, such as messing with the lighting, furniture, or climate controls. Otherwise it really would involve some kind of subterfuge with the opposing player' entourage, either getting information from them, or supplying some kind of information to them that convinces the opposing player to change strategy in a way that can be predicted. But even for the latter, is that actually cheating? If somehow I communicate to the opponent's friend(s) that I've studied all of his opening moves and thus he chooses an alternate opening move altogether, is that actually cheating?
If they didn't catch him somehow taking instructions from someone in the audience then I guess I just don't see how he's cheating without some kind of clear description of the mechanism by which he's cheating.
