Re: Transposing into historic tabiyas

I managed the 1946 Zita-Bronstein game at the weekend, albeit from a round the houses move order. [SetUp "1"] [FEN "r1b1r1k1/1p3pbp/1qpp1np1/p1n5/2PNP3/1PN3P1/PB1Q1PBP/1R2R1K1 b - - 6 14"] Instead of Bronstein's .. a4, I played the plausible .. Ng4, taking advantage of the point that h3 hadn't been ...

Re: ECF Grading Proposals

How else would you expect it to be done? It would be theoretically possible to run it the same way as the grade recalculation of a few years ago. Namely start with data a few years back, run the new player estimation method on everyone and roll forward from there. That ranks players, but an arbitra...

He reportedly passed away a few days ago, having been one of the last prominent "pre-Fischer" chess figures still living.
How many of the opposition in "60 Memorable Games" are still with us? One at least, the co-winner of the rapidplay at the Torquay British this year.

Re: Specification for ECF LMS API ?

How about using the format of that Excel file as one of the acceptable tournament report formats? I thought Swiss Manager had already been customised to produce an ECF compatible grading file output. That presumes the organiser had been bothered enough to ensure the ECF grading codes were present.

Re: ECF Grading Proposals

It is, by the way, downright insulting of you to say that we spend a lot of time producing documents ‘designed not to be read in detail’. Why then does the Board not identify proposals likely to be controversial and require specific endorsement for them? Business plans are notorious for being long ...

Re: ECF Grading Proposals

The monthly grading proposal was included in the Strategy and Business Plan submitted to and approved by Council at both the 2017 and the 2018 AGMs. I would consider it sufficiently important that it should have been a motion in its own right, rather than buried in a document designed not to be rea...

Re: ECF Grading Proposals

But the consultation with results officers came only after the public consultation exercise (with its predictable result) and concerned implementation details, not whether the whole thing is a good idea or not. This is not a good way to go about making a decision and it puts noses out of joint of p...

Re: 4NCL Rules 2019 - 20

One change that didn't make the "Main Changes (from 2018-19)" list on their website is that games on the Saturday of the last weekend will start at midday. Why? Is that to do with the Bank Holiday move to the Friday? The established time for the middle round of the three on the final weekend has lo...

Re: Specification for ECF LMS API ?

We expect to introduce an event registration system, so we can keep track of what is expected to arrive. Our vision is that organisers can apply through calendar entry and with a few more details than now, registration will happen. What details would these be? Congresses, even one day ones, would w...

Re: Cheating in chess

Like what was he doing and why was he doing it. You can certainly improve your rating by studying openings etc. Even more so if you do it whilst the game is in progress. Pity they didn't ask what the story was about all those sacrifices against Keith several years ago as to whether he made it up ov...

Re: Game Changer - a review

If against Stockfish, or any other opponent, after 1.e4 e5, AlphaZero's opponent plays 2.f4 then AlphaZero would have to play against the Kings Gambit and either accept or decline it. I don't think any public domain analysis as yet surfaced as an analysis of the King's Gambit using AlphaZero method...

Re: Where did I go wrong?

Bermuda's Olympiad captain, Nick de Firmian, was an early theorist in these lines and I remember that he preferred 14.h4 to the piece sacrifice. Bronstein, possibly not in the context of sharp Sicilians suggested you should work these things out in the peace and quiet of home study, rather than con...

Also, it is a compulsory membership scheme for graded chess, but that has never bothered me in principle.
Don't forget visiting foreign players.

Re: Specification for ECF LMS API ?

We have settled on publishing an old style grading list for next August; our objective is to have a beta version of the new system working early in the new year bringing it up to a standard to take over thereafter. So there will be an August 2020 publication of traditional three figure grades. That...

Re: Specification for ECF LMS API ?

The ECF recognises that monthly grading will only work if we abolish much workload that graders do at present. We have to develop tools that can facilitate this desire. Something that enables the existing League management systems to easily submit results would therefore seem desirable. A utility t...
