Talk about a buried lede, I can't believe that they allow caught cheaters to simply reset in rankings and never publicly name them. Can you imagine any other sport operating that way?

Wouldn't it be noticeable if someone got their ranking reset? So others can easily infer who got caught?

This report provides a detailed background of Hans' potential cheating, and detailed breakdowns of certain aspects of chess.com's cheat-detection methodology, including previously unknown (or little known) methods such as window focus change event monitoring and post-focus-change move analysis.[1] The report also reveals Niemann's engine move correlations alongside over two dozen chess Grandmasters who have admitted…

I can't speak for SV, but I think a 72-page report from every confessed past fraudster that's engaged in what seems to be fraud-adjacent activity would do wonders in clearing the crap out of the crypto scam space.

Exhibit C is about another unidentified player, not Nieman...

Sorry, I didn't read your comment carefully. I also wonder if there's enough information there to identify the players

Redditors are certainly speculating [1] who could be the 4 confessed cheaters in the top 100.

I suspect something like “everyone cheats online” is kind of what we have here, and they’re a bit worried about upsetting the whole applecart.

Which gets to my point about the bias of chess.com. Surely they have an interest in making this look like one awful offender, a bad apple essentially, and not that they’re profits come from a broken sport.

If they have that interest, why did they just release a detailed 72-page report in which they make clear that there have actually been many offenders?

Your argument doesn't hold much water.

It was a line that Magnus has already played once or twice in tournament. Hans wondered how Magnus could surprise him. So Hans studied various lines rarely played by Magnus including this one. This was very clear in Hans interview.

did you even read the chess.com report? > In fact, Magnus has only played 4.g3 twice previously (both before 2010), and the position after Hans castled on move four had never been seen in any of Magnus’ games. Hans in a later interview commented that Magnus had previously played the opening against Wesley So in the 2018 London Chess Classic,24 but there is no such game on record.25 Magnus did play a g3 Nimzo-Indian a…

Hans have studied this line because Magnus played it before. Was the line exactly the same: no, he explained that he spent several minutes to evaluate if the transposition was possible. I'd rather believe Hans than the far fetched cheating theory. Magnus just was on full paranoia mode. Everybody agrees that both of them played poorly and that Hans even gave situations where Magnus could have won.

That's why I quit playing seriously when I was still an underclassman. It was overwhelmingly obvious that merely being well above average was completely irrelevant, and there was absolutely no practical reason for me to play chess whatsoever. Although it did subsequently get me laid once or twice, which in retrospect still surprises me.

Don't leave us hanging!

No...they seem willing to provide evidence that he has cheated more times than he admitted. He did NOT keep his side of the deal

Where did you read that in the document?

Search for "admitted" and it is on page 2.

People can still cheat with some hidden hardware I guess [0]. A full body inspection of each player would be required as well. —— [0]: https://github.com/RonSijm/ButtFish

Most of the _plausible_ systems involve a one-way link, where an observer is running the engine and supplying information to the player through some system that is perceptible to the player and nobody else. Forcing the player to pass information about the board state _outward_ certainly doesn't make cheating impossible, but it makes it a whole lot harder - input devices that can't be observed are much more difficult.

Maybe that one way link is as simple as high frequency sound, that he's trained himself to hear which everyone else ignores. Simple on/off modulation, or maybe two freq modulation...

The amount of data required to communicate a chess move is very little.

>>Online chess is bigger than ever, and some kind of botting/cheating is possible for virtually every e-sport (indeed I'd say many are easier than chess). I think it's the other way, chess is about as easy to cheat as it gets. With chess you can have a perfectly usable cheating system that isn't on the same computer at all - computer A is clean, and is where you actually play on chess.com, computer B is where you ent…

It's not just AI and e-sports either Fishermen Team Accused of Cheating by Stuffing Fish With Weights https://www.si.com/extra-mustard/2022/10/01/fishermen-team-a...

This however is easily detectable. It is undetectable whether I have a second device showing me calculations of a different engine.

Does engine correlation actually prove anything though? Some of the 'statistical analysis' that has been posted on twitter regarding it in the last week has been against hundreds of engines, so 'engine correlation' seems to mean "the move made matched against at least one engine that would have made that move" I think?

Am not a statistician, but at least in an online analysis I saw, seems like correlation can effectively identify players who are playing too much like a computer. Because they don't just run correlations on Niemann, but on all the top players, and do comparisons (and for certain long stretches of tournaments, Niemann's is playing way, way above how anyone else has ever played). This is video explains it pretty well,…
