Hikaru could have followed the game with an automatic engine evaluation, that would make it 'slightly' easier for him to '~immediately' evaluate the position with better precision.
You are comparing a tired guy answering the questions on the spot to a person who could have had all the computer help in the world (and they do when they are following live matches).
Like compare hans to alireza in their interviews. Hans clearly just has a worse understanding of the position he chose to go into.
I mean to me it feels less like cheating and more like just absolutely wild prep, hans played like a 3200 up to the midgame and then couldn't convert a winning position, but it's suspicious to have such completely insane prep, especially without clear compensation
The interviewer (Alejandro Ramirez, also a GM) asks Hans what happens if black takes the knight on c4, which didn't happen in the game but is the engine's best move. Hans says Bh6, starts down one line with g6, Bg5 (good moves) but backtracks the latter and blunders with f4, and says "At this point my pieces are literally perfect, his pieces are terrible" (Hans is -2). The position in the video is two moves later. By then white is completely lost, but Hans says black has no chance.
As for his 'blundering' in a live Q&A talk, that's not indicative at all, I have posted my reasoning in a sibling comment.
There are two answers to this question. One is obvious and is the subject of the article we're all responding to: Cheating. Some people think he's cheating.
The other is that nobody actually thinks Hans is terrible. Even if he cheated he's still at least a 2500-level player and perfectly capable of taking the odd game off of super GMs. Being very good and cheating aren't mutually exclusive possibilities.
> that's not indicative at all
The word you want is conclusive. The interviews are certainly indicative, but they're very far from conclusive.
No. The word I want is indicative, as in "Serving to indicate; Pointing out; bringing to notice; giving intimation or knowledge of something not visible or obvious".
Giving "imprecise" analysis at the Q&A session does not mean anything at all, and of course it can't be used as an evidence of any kind that a cheating took place.
Specifically on this, I agree with you. Who knows if he's just nervous at giving interviews.
