Re: The English Language

Whaat does 'resspectively' refer to? Studies using clustering algorithms, similarity/dissimilarity measures, and evaluation criteria reviewed in Section 2.1, 2.2, and 2.3, respectively , are as italicized. Does it coves just its clause or the whole sentence? It means that section 2.1 reviews studie...

Re: The Turk v Mephisto

Is this grading record him or someone with the same name? http://www.ecfgrading.org.uk/new/menu.php?file=player&PlayerCode=295297L Perhaps unsurprisingly, given the somewhat unusual name, it is the same person: This was also the debut for former presenter of TV science programmes, Adam Hart-Davis, ...

That's interesting - seems like TCEC are using the same rules.

I don't know for sure, but I suspect it's somewhere in the rules of the tournament - ie as soon as you get to a tablebase position, the result is whatever the outcome would be with best play, regardless of move limits.

Re: Lomonosov tablebases

There was an interesting finish involving tablebases (actually 5-piece not 7-piece) in the TCEC Superfinal between Stockfish 7 and Houdini 5 in November last year. This is the final position, with Black to move: K5Q1/8/8/8/5bb1/6k1/8/8 b - - 0 72 Both computers had been evaluating the position as a ...

Re: The English Language

What's the difference between 'Black has played quite well' and 'Black has played very well'? it's a matter of *how* well, with "very" being more well than "quite" so if you think of "well-ness" as being on a sliding scale from 0-10, with extremely badly = 0 and brilliantly = 10 then "quite well" m...

Re: The Rookie

What's the best choice for Jonathan to spend his time on: a) chess or b) the piano? I vote c) Jazz flute... 8) Anyhow, for what it's worth, I'd like to improve at chess because (within reason) I like to try and improve at everything I do - I find things much more fun that way. But (like many others...

Re: Chess Book Idea

I had a chess book idea a couple of years back that I don't think I've ever seen in quite this form - I don't think I've mentioned it on the forum before (but please accept my apologies if I'm repeating myself). My thought was that I'm graded somewhere round 180, so typically when I play people 190-...

Re: 2017 FIDE Women's World Championship (Tehran)

Tan managed a draw from a position she was getting toasted in but that's the Armageddon finish for you. Not sure how anyone can take this event seriously. It's somewhere between a joke and a lottery (or maybe both). :roll: :roll: :roll: Remember when Svidler hung a rook in the final of the World Cup?

Re: ECF grades compared with FIDE ratings

Happy to do a bit more analysis now I've got the dataset together if anyone's interested. The "new" URS ratings still have limited credibility, but how does the ECF to URS conversion look? Apart from some seemingly spurious data every player with an active FIDE rating has a URS rating and vice-vers...

Re: ECF grades compared with FIDE ratings

This has cropped up in another thread. Would an update be possible? I ask that with no idea of how much work is involved. I've downloaded the FIDE February 2017 list and compared to ECF January 2017. I can't remember exactly what I did last time so just matched up all people with ENG, SCO, WLS nati...

Re: ECF grades compared with FIDE ratings

The best fit line across all these data points is FIDE = 7.4 x ECF + 690 - alternatively (with rounder numbers) 7.5 x ECF + 675. This has cropped up in another thread. Would an update be possible?

Re: WORLD RAPID & BLITZ CH - DOHA 2016

I just tried to find Nakamura-Grischuk on the livestream and ended up watching bits of the prizegiving instead. It is quite funny to watch. Ivanchuk clearly doesn't like being showered with glitter and confetti at the end. :lol: (Round 19 is from 2:57:30 on the 4 hour+ clip for rounds 13-21 of the ...
