Do you have a source of Magnus accusations? He seems to have withdrawn relatively quietly, perhaps consciously trying to refrain from cheating accusations.

Hikaru was less reserved on the other hand. He called Hans's post-game interview analysis sub-2700 level after Hans Neiman badly mis-evaluated several positions.

His tweet included a video of a famous interview with Jose Mourinho saying “if I speak I am in big trouble”

Yeah I think he's being very professional instead of just throwing out accusations; let the arbitrators call that.

I'm not at all into chess (only through the odd HN post where I get out-nerded left, right and center), but I can imagine it ends up being a very analytical thing, where the experts or analysts can spot whether someone is playing like a human or a computer. And I also think they can't add "noise" (e.g. human mistakes) to it either, that'll either throw the computer off, OR it'll look "uncharacteristic".

Not a member of this forum, but wanted to help a bit here.

First off, computers are (especially in complex positions) ridiculously stronger than humans, like your average family car can't keep up with a Ferrari. In less complex games (like an endgame with fewer pieces) top-10 players can definitely play 20 perfect moves in a row, in an attacking game that's harder. A player like Niemann is not really expected to reach that level in a game like this.

A second point is how much time you spend on each move. If you play a move with big consequences (say sacrificing material, or violating a principle) you would generally think longer. A computer doesn't see it that way and might spot "instantly" that this move wins material 7 moves down the road, where even a World Champion will check his analysis before playing that.

So playing too perfect and playing too fast in critical positions are both red flags. In Online chess, they often use this to grade your moves, and flag you if you go over certain thresholds, especially if you have a lower "rating".

Hans Niemann did both of this (too fast and too good) and then after the game was not really able to explain his thought process afterwards. None of this is hard evidence, but they are red flags, and if you add that Niemann has been caught before in online chess... that's so many red flags it would make the CCP proud.

Hope that helps a bit! So no, there is no very analytical thing, which does mean we need to be a bit careful and leave the option open that Niemann maybe just really liked this move on general grounds, got lucky it worked, and has learned of his previous mistakes. It could definitely happen.

Nothing really throws the computer off. It is objectively much better than any human at evaluating any position, not just the types of positions computers get into.

Magnus didn't make an overt accusation: it was other chess experts who read that into the circumstances of his withdrawal &c.
