Re: Some thoughts on anti-cheating systems

As a university teacher I used to plot the distribution of exam marks and I very rarely got a normal distribution. My distributions more commonly resembled a two humped camel with maxima in the mark ranges 40-55 and 70-85. When we fed the marks into university marks system it would calculate mean ma...

Re: Some thoughts on anti-cheating systems

If you don’t want to wade your way through all of this I’m basically backing up OP Roger’s points that statistical inference may not work so well when applied to events resulting from human decisions. I wonder if anyone here has read any of the works of Nassim Nicholas Taleb (Professor of Risk Engin...

Ah, but it's well known that grading systems don't work for lighthouse keepers!

Re: Could everyone lose their grade

The Clarke grading system is 66 years old (born 1954) and it's being pensioned off!

Re: Bobby Fischer on BBC 2 Friday 15th May 2020

I enjoyed the film too, despite the historical and technical errors (I nearly fell off the sofa with astonishment when one of them said "check"). Anyway my major quibble was portraying Fischer as believing in a worldwide Jewish conspiracy in 1972 - I thought this (and his mental illness) came later?...

Re: Can online chess ever beat the face-to-face over the board experience?

Did the Clapham Common club in London have an inside venue? When I lived next to CC (1973-75) there were chess tables on the common itself and you saw people playing but whether they were members of the CC club or CC club members ever played on the common, I never discovered. (The CC clubs won vario...

Re: ECF Finance Meeting

There is a case for making the Council Forum private: many people (including ECF board members) have told me over the years that they would never post here. (Of course we all value the cut and thrust of honest debate, but many non-posters regard this place as a bearpit.)

Re: Plaskett and Woffinden's book on the "Who Wants to be a Millionaire?" Fraud

I disagree. I think it is worth discussing partly because there is an established overlap between chess, the quizzing world and possible cheating.

With Mark Murrell's permission I have posted the ECF proposal for an online County Competition on the Guildford CC website. You can down load it from this link: http://www.guildfordchess.co.uk/wp-cont ... CSec-2.pdf.

Theoretically it should be 80, but I guess a case could be made for 75.

Re: Media comments on chess

Further to the Reykjavik 1972 query a colleague from Guildford Chess Club who was reporting on the match tells me he can't remember any posters in the toilets, either. However, he adds that this is the sort of detail he probably wouldn't have noticed anyway. He sent me a nice image of the original p...

I seldom make comments about fellow arbiters on this Forum and on this occasion I can't. The Chief Arbiter is IA Nuno Felipe Andrade. I have to confess that I had not previously heard of him.
This looks like an anagram of April Fool in some vaguely recognisable language.
