Re: 2nd Cambridge International Open

In terms of the terminology of the new ECF rating rules, FIDE uses the K formula approach to calculate TPRs whereas the 400's formula uses the P formula approach. You can find details of how P ratings are calculated versus K ratings on the ECF rating site under "Help". So why is there such a big di...

But that said "File not found".
Good!
The FIDE rating change calculator is not much use either.
Is there a way to reach that directly via the website rather than through a search?
From the menu option at the top:

https://ratings.fide.com/

Click on 'calculators'.

Re: 2nd Cambridge International Open

Thank you Roger. I tried to use the FIDE rating calculator here:

But that said "File not found". The FIDE rating change calculator is not much use either.

Re: 2nd Cambridge International Open

Anyway, maybe it is best not to dwell on it too long or in too much detail, as Fava appears to have gained 138 rating points(!) and must be close to 2300 now, and has a draw with the current British Chess Champion under his belt. Agreed, I think far too much fuss is made about title norms ( and tit...

Re: 2nd Cambridge International Open

That's what I thought as well, but then I put the numbers in here: https://www.englishchess.org.uk/wp-content/uploads/2012/01/CalculatorPage.html This needs some context. What do you believe the output is supposed to mean? Because I am lazy about calculating a TPR for 6/9, I thought that a random T...

Why is that calculator telling me the adjusted TPR is 2443. Is it doing some adjustments under the hood?

Re: 2nd Cambridge International Open

Fava needed to have played at least four players who weren't Italian (he did), three players who weren't English (he didn't), and players from two non-Italy nationalities (he didn't). The Lithuanian FM Aras Vardanyan might be a good example of how it was possible to meet a good mix of federations i...

Re: 2nd Cambridge International Open

My question still stands, if they had been present for all nine rounds, would a non-ENG WGM or WIM (or indeed another non-ENG IM or GM) have meant the exemption requirements were met? Yes. And what exactly was the reasoning behind the 20 and 10 figures? Plucked out of thin air, or were there reason...

Re: 2nd Cambridge International Open

I count 9 non-English IMs and GMs. Am I right that if there had also been a non-ENG WGM or WIM that would have met the requirements? No. You are including one player who never arrived and another who was missing from three rounds. Well spotted: Bogdan Borsos is the Ukrainian IM who was missing from...

Re: 2nd Cambridge International Open

Fava needed to have played at least four players who weren't Italian (he did), three players who weren't English (he didn't), and players from two non-Italy nationalities (he didn't). I do feel a bit sorry for Fava (not too sorry as he may well get the rating and norms later) as I am not entirely s...

Re: 2nd Cambridge International Open

I did have a look to see whether this tournament has enough foreigners for an exemption, but I don't think it has 10 non-English IMs and GMs. Would anyone be able to clarify the exact caveats and exceptions that applied here? I think I understand them but am not entirely sure. https://handbook.fide...

Re: Chess books and film (and other culture)

Resurrecting this thread (last posted to nearly nine years ago) to add in a couple of literary examples of chess that I metioned in a different thread, but which really belong here: I cannot remember if we have a thread for literary allusions to chess, but in case it is of interest, I happened to be...

Re: 2nd Cambridge International Open

Any norm chances? I have been looking at a few likely candidates, and I cannot make head or tail of it... Lorenzo Fava looks like a potential IM norm, but he has played all ENG, so does that throw a spanner into the works? Jonah Willow is playing a third GM, but I have no idea what his adjusted perf...

Re: 2nd Cambridge International Open

The way Tiviakov's position (as White) in round 8 went from winning to losing is quite instructive. I last looked at the position just before White's 34th move, and was very surprised to look again just now and see that IM Martin Haubro (now the new tournament leader) had won! There was a five-point...

Farnworth, Bolton A chess board has been set up in Farnworth in hopes it will encourage young people to take up the game. A table and two chairs with a chess board glued to the table has been installed at Farnworth Park. Last year, it was announced the council had won a £5,000 grant for two chess b...
