Exclusion of players from rating

Post by Roger de Coverly » Fri Feb 17, 2023 12:36 am

The details of the forthcoming Coventry Open this weekend (18th/19th Feb) are at
http://coventryopen.warwickshirechess.o ... n_2023.pdf
from which
Rating
The tournaments will be submitted to FIDE for international rating and the English Chess Federation (ECF) for national
rating. Games played involving a player FIDE-rated in excess of 2400 are ineligible for FIDE-rating
Possibly because of the overlap with the Cambridge International, it's academic as the top seed has a FIDE rating of 2154.

What point are you making? If the event had not been registered for FIDE rating, then all games would be "excluded".

As far as I am aware it's the first British event to exclude players from rating on an individual basis. That's academic with the top seed under 2200 but a potential issue for the handful of active weekend Congress players with ratings over 2400.

In what way is it an issue? My impression is that most >2400 players take their FIDE ratings seriously and are happy that quickish games aren't counted.

It's a decision you have to make if you're running a FIDE-rated event at faster than G/120 time controls: do you make it a de jure U-2400 event, or do you allow 2400+ players to enter but not rate their games? I suppose there are things to be said for both.

If the "secret" ECF Grand Prix (last updated 11th November) is relevant, the version not rating 2400+ would be included presumably. The U-2400 wouldn't on the evidence of the absence of Adam Raoof's events. I think inclusion in the Grand Prix is relevant for qualification for the British Championship, which may be an issue for players under 2200.

FIDE will allow tournaments offering three games a day to be rated without restrictions but only if it's a twelve hour playing schedule. What is the ideology behind denying full rating to games nominally lasting three and a half hours?

I can see nothing to be said for the first.

This has been well discussed. It is not considered desirable that Candidates places, for instance, should be decided by ratings based on shortish games. So you have to put a limit somewhere. I think 2400 is a sensible place.

It avoids the disadvantage of the second approach where players will probably not be best pleased if their actual performance is to their rating, but they lose rating points because they achieved that by beating a 2400+ player and losing to a lower rated player. Of course, it's also not right that a reversal of those two results would result in them gaining rating points when they had still only performed to their actual rating.

I thought that 2200 was the point where 4 hour games were required by FIDE which I thought was why Adam set that limit. Did that get changed to 2400, or am I mixing things up?

It got changed, I think during the lockdown closure, which is presumably why Adam changed his upper limit. Where they don't have Friday evening rounds, many long standing weekend tournaments have stuck with three and a half hour sessions, open to all and ECF rated only.

If I have read Roger’s post correctly, the whole game would not be rated if one of the players were above 2400, so the player below 2400 might be disappointed, even if the player rated above 2400 were not.

We certainly felt that you couldn't have a game rated for one of the players and not the other - even though at a lower level that is what happens with players on their first few rated games.

You are actually mixing up two things which are actually distinct:
  • The ECF Chessable Grand Prix : money to be won, any ECF rated standard tournament is eligible (presumably even 60+0 events) as long as it does not have a ceiling (it can have a floor). Rapid tournaments are also counted. Rather simple way of counting points.
  • The British Grand prix, which can qualify to the British championship: any FIDE standard rated tournament of 5-8 rounds with no ceiling (floors are ok). This pretty much requires a 4 hour game. Complicated point system.
Thing is, most fide rated tournaments have a ceiling which disqualify them from both grand Prix.

By the way the ECF grand Prix leaderboard is now updated as at December 1st.

Both lack publicity though and are I would suspect are driven from the rating list. Do you have a link to the qualification list for the British?

The Grand Prix is up to date only to December 1st

Seemingly I'm third in the under 2050.
