Re: Raymondo

Re: Status of Project?

If the idea behind it was to help fund Chess for Schools, then given his experience, he would have made it crystal clear that this was the case right from the start of the event. Indeed. From the daily reports (round 1) http://www.howardstaunton.com/hsmt2009/Reports_-_Rd_1.html Predictably enough, ...

Re: Status of Project?

Re: Game search

Your first guess was correct. Where was it played, do we know? Only info is "Austria". It seems to be a game which found its way onto the historic databases as a one-off. I didn't find any other games that might have been part of a match or tournament. www.chesslab.com implies it's from a match bet...

Re: Game search

Whilst the Chessbase online database has: [White "Dueckstein,Andreas"] [Black "Lombard,Andre"] The Olympiad game certainly looks plausible. My data source has Lombardy - but AUT played SUI and not USA in that event. But Swiss players were always playing Austrians - so they could have met more than ...

Re: new grades wow brandon clarke shot up 206

He scored a staggering 7.5/8 for Warwickshire select last season in the 4NCL Of all the juniors whose grades are off the scale, Brandon is not one of them. Danger signals for the out of control new player estimation recursion (a) very high (or very low) percentage score (b) played against unrated o...

Re: Reluctance to Align with FIDE ELO?

Given the difficulty in assigning an accurate Elo equivalent to an ECF grade (I know of no calculation that will do it satisfactorily) I suspect what you'd be looking at is this week's controversy all over again - but bigger. I actually think the attempted regrading shows us a possible template for...

Re: Raymondo

Close the thread on the grading system, that is boring. Perhaps. But the ECF have introduced some major changes of both practice and principle into their grading system. The thread is acting as an audit of these changes. In fact in the absence of clear statements from the ECF it's even just trying ...

Re: When is the new grading list coming out?

Any ideas how you would get a grade of 32 with those results? Well it's 1.5 from 9 and there's an unrated opponent in there. It's just more evidence that the estimation program runs amok when confronted with unrated players and "extreme" results. "extreme" just seems to mean something like 1.5 from...

Re: When is the new grading list coming out?

What I mean by "the junior problem" is the deflationary affect on grades of a a large group of improving players. This was recognised by Richard Clarke who proposed (even if he did not implement it himself) correcting the grades of junior players. However, it's not just the deflationary effect on a...

Re: When is the new grading list coming out?

Perhaps the simplest way to grade new players to the grading system would be to "ignore" grading results, and estimate them instead, not based on statistics, but on their apparent strength of play This is the way it used to be done of course when local graders had a greater input into the calculati...

Neill Cooper wrote:His grade was worked out from a base of 68
So after publishing a supposed regrading to one hundred and something, they then ignore this completely. If you don't chain in some manner grades from one year to the next doesn't the whole system collapse? Confidence in the system collapses.

Re: When is the new grading list coming out?

Then there is no attempt to fix the junior "problem" this year How would you define the junior "problem". If you accept that junior strength is volatile and inconsistent, then no attempt to "validate" a begin season strength estimate against later actual results is going to be successful. You might...

Re: When is the new grading list coming out?

[ Looks like a bug in the program. Possibly the 114 grade for this player was some previous iteration before the grades had converged. Noticing that your son's grade had allegedly collapsed to 73, 114 is 41 points above this - so maybe the issues are connected to the 40 point rule in some way. Seems...
