New ECF RATINGS Are Out

THE English Chess Federation is switching from three-figure grades to four-figure ratings, which will be compatible with Fide elo ratings.
The switch means my ECF grade of 173 is replaced with an ECF rating of 1998, which is a straight conversion using the formula ECF x 7.5 (+700).
So the introduction near the top of my blog now reads:
"I begin this blog after getting back into league chess following many years' absence due to work. My post-job status also means I am able to play more tournament chess. My new club in London is Battersea and my first game for them is on Thursday September 14, 2017. I start with a Fide rating of 1858 and an ECF grade of 169 (=1968 elo). My latest Fide rating (Sep 2020) is 1813; my latest ECF rating (Aug 2020) is 1998."
As can be seen, my ECF rating is considerably different - 185 points - from my Fide rating.
ECF ratings, like Fide ones, should now be updated monthly.

New ECF Grades Out Today!

MY grade in the new six-monthly list from the English Chess Federation has edged up from 168 to 170.
The new grades only marginally affect my last three performances for Battersea.

Overall this season for Battersea I have scored +1=4-6 for a grading performance of 156.

In season 2017-18 I scored +10=8-9 for a grading performance of 175.

What Are The Odds Of This Happening?

A CURIOSITY from the weekend's 23rd 4NCL congress.
In round two of the U2000/175 section I was paired against Rob Tokeley of Burnley, who has an ECF grade of 152 and a Fide rating of 1840.
The remarkable thing about this - and I really think "remarkable" is not too strong a word - is that a grade of 152 converts exactly to a Fide elo of 1840.
The current conversion formula, which was introduced by the ECF in February 2014, is:
ECF grade x 7.5 (+700) = Fide elo
So 152 x 7.5 (+700) = 1840.
Usually when a grade and a rating match in this way it is because a tournament organiser has converted a grade for an English player who does not have a rating (and sometimes a conversion is made from a rating to a grade for a foreigner who is not registered with the ECF).
But in the case of RT, his grade and rating are separate entities.
I cannot recall having ever played anyone before whose ECF and Fide exactly matched (but it may well have happened without me noticing).
My ECF of 168, for example, converts to 1960, although my actual Fide is 1927.
That is a reasonably close match - many players, especially juniors, have much greater discrepancies.
The main reason for these discrepancies is undoubtedly that most people who are registered with the ECF play many more graded games than rated ones.
The situation is changing.
The vast majority of league chess that comes under ECF auspices continues to be graded and not rated. That used to be also the case with tournaments, particularly weekend swisses.
However, increasing numbers of congresses are submitting results to Fide, and not only of open sections. Adam Raoof's near-monthly Hampstead congresses, for example, now feature three sections, each of which is sent for grading and rating.
My experience of playing this year, while by no means typical of most players, is illuminating.

"Leagues" includes internal club games and the Pimlico summer tournament organised on a one-game-a-week basis

If I have got the numbers right (I found the table to be quite a tricky construct, as can be seen!) I have played 187 games in 2019.
Of those, 151 are/will be graded and 135 rated, so both my ECF grade and my Fide rating can be regarded as fairly accurate, which is no doubt why they are in rough alignment.

The performance that stands out is that of John Merriman (2201/214) winning the Open ahead of a field that included two GMs, one IM and three FMs.
Incidentally, the Sam Davies who won the U2000/175 performance prize had a fairly useful coach in attendance - his father, grandmaster Nigel Davies.
The prize money in each section totalled £1,000, so £3,000 in all.
The number of entries was 125, according to the 4NCL website, although only 121 players actually took part.
Multiply the number of entries by the entry fee of £30 (ignoring pay-to-play fees that presumably go completely to the ECF) and you get £3,750.
In other words, 80% of the entry fees were returned in prize money.
The playing hall - all games were played in a single room at a Holiday Inn in Derbyshire - was spacious, if rather overheated.
It seems to me the 4NCL has found a winning formula for weekend tournaments as well as its better-known league chess.

New Grades

NEW ECF grades, effective for the period July 1 to December 31 (for some reason, the ECF site says December 30, but I suspect someone has numeracy problems), have been published at http://www.ecfgrading.org.uk/new/menu.php I have slipped from 171 to 168.
The new grades mean my weekend performance in the 4NCL U2000 at Telford has improved from 173.8 to 181.8, which makes me feel less guilty about having won £190 for what appeared to be a more-or-less par performance.

Marching On

MARCH has been my busiest ever month, as far as I can recall, for team chess.
For Battersea I lost to a 174, drew with a 169, drew with a 159 and beat a 165.
For Sussex I lost to a 173 and beat a 171.
For Hastings & St Leonards I beat a 148 and drew with a 152.

My updated first-season Battersea stats (CLL is Central London League; LL is London League):
Event..............Colour...Grade...Opponent's Grade...Result
CLL................White.....169.........183............................L
CLL................White.....169.........197............................L

LL....................Black......163........165............................W
*Opponent has no official grade. Last published grade was 172 in 1997, which was pre-recalibration, and he was in the 180s before then.
Overall for Battersea I am +4=6-8 for a grading performance of 164.

Overall for Sussex this season I have lost to a 172, beaten a 169, lost to a 173 and beaten a 171, for a grading performance of 171.

Overall for Hastings & St Leonards this season I have beaten a 156, beaten a 148 and drawn with a 152, for a grading performance of 185.

It is said you can prove anything with statistics. That is an exaggeration but, despite my 185 grading performance for Hastings, there is no way I would rate my results there as better than my results for Sussex.
Indeed, it could be argued that my results for Battersea (no losses against lower-graded opponents, but a win against a higher-graded opponent, and with four of my six draws coming against higher-graded opponents) are better than for either Hastings or Sussex. I guess it is just a quirk of the English Chess Federation grading system.
