Re: Some thoughts on anti-cheating systems

Roger,
“ The essence of a normal distribution is that it relies on successive events being random or independent,”
This is just wrong

Re: Some thoughts on anti-cheating systems

Roger, I have a titled player account at Lichess and a normal account at chess.com. I could give you access to my chess.com account which has an established history of playing at a reasonably high level and you could attempt to use your computer to mimic that level of play or push it higher. You wou...

Re: Some thoughts on anti-cheating systems

Mick,
You have identified a problem and I don’t know the answer. Maybe in years to come county matches will be a different format, I.e each player playing 6 games, so that it is likely that a player will build up enough evidence after one round to detect cheating.

Re: Some thoughts on anti-cheating systems

Mick,
You cannot do that in OTB events so why do you expect to be able to do it in online events?

Re: Some thoughts on anti-cheating systems

Roger, If I understand you correctly, you are now talking about a hypothetical example which has nothing to do with anything that is happening in British Chess or anything that has happened historically. You’ve got me, I don’t know. Matt - You evidently don't. I'm not discussing a hypothetical exam...

Re: Some thoughts on anti-cheating systems

Roger, What like actually looking at their terms and conditions? From Lichess See the following for some examples of what you shouldn’t do. 2. Artificially inflating or deflating your rating. This is where a User purposefully loses, or has arranged with an opponent to win. As a result, the User’s ra...

Re: Some thoughts on anti-cheating systems

I'd be a tad more cautious than Matt and, since this is something I seem to have omitted from my earlier post in an effort to keep it to a manageable length, I'll try to explain why here. Some while ago, a previously completely unknown teenager emerged on the English chess scene playing to a standa...

Re: Some thoughts on anti-cheating systems

I hope the individual or their parents would go through the appeals process as outlined in the ECF fair play policy and this would pick up any false positives before it reached a court. Might the ECF get sued, well yes, but the ECF might get sued for lots of reasons - welcome to modern life.

Re: Some thoughts on anti-cheating systems

Mick, I think everyone accepts that false positive do happen and the Lichess representative certainly accepted (not conceded) that point, in response to a question I asked. I meant the statement that is was highly unlikely that there were two or more false positives in the 4NCL to be tasked at face ...

Re: Some thoughts on anti-cheating systems

Mick, We were told last night that those flagged by Lichess were pretty evenly spread across the leagues, but demographically they were predominantly young players. False positives do happen, but from what I have seen I would say it was highly unlikely that there were two or more false positive in t...

Re: Some thoughts on anti-cheating systems

Now you need to answer why that hasn’t happened in the online 4NCL when the same ratings were used. The hypothesis is that some of the players were using external assistance when playing online. Without witnesses that's next to impossible to prove or disprove without resorting to statistics. It was...

Re: Some thoughts on anti-cheating systems

Pretty reliable for 4NCL players I’d say. At least they have been reliable enough to keep all the performances in the expected area. Now you need to answer why that hasn’t happened in the online 4NCL when the same ratings were used.

Re: Some thoughts on anti-cheating systems

The Ken Regan tests are calibrated (as you put it) over millions of historic games to assure the accuracy. Sorry to be persistent, but where can I find this? It is precisely the information I have been requesting since 2013, when I was on the original Anti Cheating Committee. I am assured that it i...
