GM Tigran L. Petrosian, violated fair play regulation, banned for life

Cheating in online chess is easy as said by someone here (more moves need to be done by yourself). This of course gets easier as the time increases, which is why online bullet is so good.

Idea of improving using engine evaluation in games, is true but unjustified, you might as well do that with someone knowing, or against a computer or something. Besides you can analyze the game afterwards with the engine.

OTB punishments need to be applied to Tigran, perhaps not lifetime. Or at least FIDE needs to announce that if they see a titled player cheating in an online tournament (money) then they will also hold them accountable.

"computerish" simply means too difficult for a human to find in a given amount of time or even just very counterintuitive.

A GM is certainly able to tell if a move is "human" or "computerish", that's why chess.com has a team of strong players (I guess GMs and IMs) checking suspicious games, they don't exclusively rely on software-judgement when it comes to ban titled players.

@Biancoazzurro

Recognizing computer play is a skill in itself. It doesn't come with a title, nor does it require one.

OTB punishment after online cheating is I think right but maybe difficult practically.

Would you punish players caught in any online-tournament with money at stake? Even if it happens on a small online-site with maybe not such a good cheat-detection software ?
And who decides that the player cheated? - The staff of the online-site or FIDE? If it's FIDE the online-site would be forced to show the evidence, etc...

How should a random player with no title be able to judge if a strong GM is capable of finding a certain move or sequence of moves?
He cannot.

Where are the games Tigran supposedly cheated? There are plenty of ways untitled players can judge if there was cheating ogle not, but I would like to see the evidence for myself.

Probably worth trusting only websites like chess.com or lichess cheating detection. Also, the idea of making those websites hand over the evidence to FIDE to double check sounds like a good one. It would be better than letting online cheaters get away and just go back to otb chess for their career.

this is one suspicious game:
www.chessbomb.com/arena/2020-pro-chess-league-finals/13-final-Petrosian_Tigran_L_-Dominguez_Perez_Leinier

Now you tell me if he cheated :)

How to explain 53.Qf4?? if it was cheating? I would not conclude anything from this game alone, or without video footage.

I was reading the translation of the armenian team press conference (link here www.reddit.com/r/chess/comments/j3xawd/armenian_eagles_press_conference_translated/) and I mean... They are right about some things regardless of Tigran has cheated or not...

1- If there was a suspicion about what he was looking at and there is a clause that they could ask the player to show something at any point in the game, why they did not do that? (they claimed that Tigran does not use a mouse but a touchpad and he looks down to avoid mistakes. But again this not the point)

2- If there was some issue regarding the semi finals as well (as reported by chess.com), why they continue the tournament?

3- And I think it goes without saying that if you are disqualifing someone and banning him you have to present the reasons why are you doing this. Not just say "Hey this guy was cheating so..."

And I'm saying that because I honestly think that chess has a huge e-sport potential and I think that cheating on online chess has to have the same weight of cheating OTB. And so the organizers have to conduct those issues as (or actually even better) than the greatests OTB tournaments.

And I must say that, so far, chess.com made a terrible job at it!
