Re: ECF to scrap its grading system

I might be saying the same thing as Richard Bates but don't assume that if the theoretical predicted results leave the ratings in the same state that that shows that the ratings or model probabilities are correct. For a set of ratings and results there is more than one set of model probabilities th...

Re: ECF to scrap its grading system

Picking up a few points in recent posts. I share Richard Bates concerns about acceptance of a radical change to Elo. However the ECF current approach to new entrants/juniors tends to breakdown with the smaller samples generated by monthly lists. The approach can be very volatile and explaining the i...

Re: ECF to scrap its grading system

In December (25th) I noted that three of seven congresses I had taken part in had not appeared in the list of events submitted to the ECF Grading team. Only one of these has appeared in the following three and a half weeks. One of those missing was fairly early in the season, end of September, whil...

Re: ECF to scrap its grading system

Not having long enough to seal a move is a problem. Especially a match not starting on time on an overrunning junior club. There are exceptions of course on starts. I think ECF will have a problem in implementing a new grading system with instructing leagues on how they can play their games. Quite ...

Re: ECF to scrap its grading system

The deadline for July (e.g.) is normally about 15th July. Leagues are normally finished in the middle of May, so a league grader has maybe 6 weeks to get the results in. I suspect there's a heavy element of graders working to a deadline, and if the deadline was tighter (as it is in January), they'd...

Re: ECF to scrap its grading system

My spies tell me that they suspect the intention is to get everyone to submit data through the "official" process, presumably a bit like Chessresults.com. Assuming ECF just uses the FIDE system, they could just use Chessresults.com! If clubs (or anyone else) don't submit results like that, the resu...

Re: ECF to scrap its grading system

It is clear to me that these changes are proposed entirely for the benefit of new players. if they play enough games against relevant opponents within a shorter period than six months then let them have a number to amuse them. But just as F grades are generally out-with most competition rules I sus...

I'm a bit shocked, Roger, that you think you are ahead of the curve on this one.

Re: ECF to scrap its grading system

The idea of monthly grading has been around for quite a while and I'm surprised at the delay in the subject appearing on this forum. The intention was in the strategy paper presented at the recent Council meeting. There are more details in the November Board meeting draft minutes. I am a rule taker ...

Re: Cheating in chess

Submissions can be resubmitted by graders and we would be prepared to alter results if instructed by suitable authority from the ECF arbiter heirarchy, although I've never seen this latter part happen.

Re: Cheating in chess

What's the position with grading those games from July onwards? They are already in the FIDE system and published, so presumably no changes there unless the FIDE Ethics or Fair Play Commission rules to remove them. As far as the ECF are concerned, again the internal club results have already been s...

Re: 44th Guernsey International Chess Festival

The Guernsey Organisers have opted out of submitting results for ECF grading, but I have been processing members elected submissions to Games Played Abroad this morning. In this situation it was not included in the ECF Grand Prix. As an open FIDE rated competition from one of the British Isles Feder...

Re: Chess.com Isle Of Man Tournament 20 to 28 October 2018

It's a reversed Vienna, surely? It's 1.e4 e5 2.Nc3 Nf6 3.f4 d5 4.fxe5 Nxe4 5.d3 with colours reversed. Indeed, and so 6 Qh5+ was in fact already known to be very bad. The same error of 5...Qh4+ in the (real) Vienna featured in Andrew Hon v Paul van der Sterren, Lloyds Bank 1993, when one of our 190...

The only thing I know about the numbers of various federations on the ECF grading list is that by far the most represented federation is {undefined}, followed by ENG.
The grading list accepts people of all nationalities. The Nation code is only added for those with a FIDE reference.
