Re: Cheating in chess

According to chess.com, "the rate of false positives detected by our algorithm is intentional." Does anyone know what this rate is, and what we think this rate should be? Seems a rather meaningless sentence - I'm guessing that it means that, if their statistical model is accurate , then they assess...

Re: Takeback requests in online games

If there's not a rule in any given competition, there ought to be. Otherwise all the pressure will be on the player who is being asked for one. I think this pinpoints one of the main problems - if an otherwise competent opponent moves his queen from d1 to d7, where it can be captured, instead of ex...

Re: Cheating in chess

Alternatively, taking my other number being 3000 players with an average of 10 games each, this would take too long for the human team simply because there were 10 times as many suspects to investigate. Yes, but we know from looking at the Chess.com cheat numbers which are in the public domain that...

Re: Cheating in chess

Matthew - you're selectively using one of the two numbers - 300 and 3000 - I mentioned. In the first case, where the typical player has 100 games for consideration, it all depends. If he or she is an obvious cheat, following Stockfish or another engine all the time, then obviously this wouldn't take...

Re: Cheating in chess

Matthew, you aren't rebutting my Lichess numbers, just coming up with what Chess.com claim. It's entirely possible that their claim is true but I've no greater reason to believe Chess.com than any other organisation with a product to sell. Furthermore, since neither platform wishes to disclose its m...

Re: Cheating in chess

And, if you go to https://lichess.org/forum/lichess-feedback/lichess-total-games-played, you'll find that - a year ago - there were reckoned to be 1.5 to 2 million games played each day. I'd guess that it's now at least 2.5 million - which equates to around 900 million each year. Some of those would...

Re: Cheating in chess

Thanks to Matthew and Ian for drawing attention to that interview, where "40-50 people" was indeed mentioned and, later, "the majority of whom are volunteers". Apparently a couple of those people are IMs along with several FMs and NMs. The interviewee also confirmed what I imagine most of us believ...

Re: Cheating in chess

Mathew reckons as many as 40-50 people are on the cheat detection team. If they need that many then sandbagging' (in this case still not proven) will be low priority. I may be wrong but my reading of Matthew's comment ["If there are 40-50 people ..."] seemed speculative rather than a statement of b...

Of course he is being, in Jonathan's idiom, a bellend. I think you can criticise lichess for not dealing with people who are being bellends well enough on this evidence. But I don't think it has direct relevance to whether they are doing a good job with cheats.
I'll second that.

Re: Cheating in chess

The reasons why some people manipulate their OTB and/or CC grades and ratings have been gone into previously on this forum. Online ratings are subject to the same thing but are more visible and can be manipulated at a far faster rate than OTB & CC ones. Returning to - "Being accused of something wh...

Re: Cheating in chess

"Unless the child concludes, as some have, that chess appears to be a game concerned primarily with accusations of cheating and is better avoided altogether." I always thought that was one of the benefits of school sport - you soon discovered that some players and officials would cheat and you had ...

Re: Cheating in chess

I'd caution against any belief that all 7- and 8-year-olds are "tyros" at chess - but that doesn't mean they fully understand complicated rules.
