Re: 4NCL Online

There might be a solution to reduce false positive rates with the blackbox of online sites- give ppl 2 online screen names, and they are only considered banned if both are. Ofc there will be those in the public that say any ban is a ban and treat it the same but it might help. Also you guys have not...

Re: 4NCL Online

The exact false positive rates to strive for aren't so important- what's important is that there needs to be some careful discussion and a decision on it, and it naturally falls on a scale amongst everything else as you guys all agree above. I think you'll find that I've never said that it's fine to...

Re: 4NCL Online

Sorry to be blunt but a criminal conviction is way worse than no longer being a chess professional overall. For a start- criminal conviction --> cant get a job around children --> cant get a job as an official --> cant be an arbiter/chess coach And when you are wrongly banned for cheating in chess y...

Re: What do you think - is this game for real?

Yup agree with game looking sus mostly from a human perspective, with 19.Bc4 and 22.e5 also looking strong to me. From a pure move comparison perspective though a lot of the game was when white was already winning- so can't really be used for "simple" cheat detection techniques such as comparing wit...

Re: World Chess Junior Squad launches £500 Tournament

Li Wu You were only uniformed because you came on and posted without correctly researching me or my new organisation. I am afraid that is a poor excuse for coming on and bringing a totally unecessary veiled attack. An apology would be welcomed otherwise kindly go and post elsewhere. Sorry as you ar...

Re: 4NCL Online

I would say that you've gotten used to the interface- and that there is more variance with rapid chess. That is, most of your opponent's have ratings that are less representative of playing strength due to lower samples themselves. But who knows- prob some other effects as well.

Re: World Chess Junior Squad launches £500 Tournament

I didn't call what you did a scam as I don't know enough- that's my point- it's very difficult to verify.

It's a pretty basic economics concept. An uninformed market participant paying for alternative goods/services that can't be verified without serious research is not a good idea.

Re: 4NCL Online

Yup- should be aware of outliers. I've actually done some amateur analysis recently using this excellent program- https://github.com/MGleason1/PGN-Spy/releases I invite you guys to do some analysis yourself. These sites use much more than just moves for cheat detection if you snoop around a bit more...

Re: World Chess Junior Squad launches £500 Tournament

Nah. Nothing personal, but especially given most juniors and their parents aren't well informed- they would do better to stick with the "traditional established organisations". Without calling this a scam, there is no way to differentiate w/e this is with an actual scam for any outsider, let alone n...

Re: 4NCL Online

Southend congress 2003! Wish I could play more these days... Yep there's a lot of wrong in the world- not sure how to solve all of them. I personally think this yardstick is OK though, as the consequence of being wrongly banned from online chess cannot compare with being wrongfully convicted. As I p...

Re: 4NCL Online

Actually I doubt sites take actual ratings into account (but it can)- as most of the players do not have real life ratings. A new, unknown 2500 player signing up does not get snap banned- so their actions must be taken due to truly extraordinary performances and/or other data that isn't revealed to ...

Re: 4NCL Online

So carlsen has a blunder rate of ~0.5% over a huge sample (blunder defined as -100 centipawns). If he makes 0 blunders in next 100 games (he won't) I will brand him a cheat.

Yes I don't envy ECF's position.

I don't envy lichess or chess.com either for deciding their policy on fair play.

Re: 4NCL Online

Some of the online servers appear to have curious ideas on this such as "playing good moves whilst in possession of a low rating". This is very good evidence if sample supports it- and in fact you can get rid of the second half of that sentence (even Carlsen blunders, and is cheating if he doesn't ...

Re: British Blitz Championships

Unfortunately you guys aren't the main core of chess.com customers. IMO it's going to be very hard to convince them to spend resources on building a proper review process. Maybe suggest that anyone with real names is automatically placed in different group to general population, requiring even lower...
