I imagined it can run chess programs.
I expect so although some need an active mobile phone. If internet enabled, it could also look up the assessment on chessbomb or similar.

What was being suggested is that all watches were banned, which I would regard as over the top paranoia.

Re: Tata Steel 10th-28th Jan 2020

People aren’t going to play in chess tournaments in large numbers because they can’t wear a watch and they get given free pens? It’s a view I suppose. It's a case of not allowing arbiters to make unreasonable demands. In the absence of a collaborator, a "smart watch" could only be used for cheating...

Re: Tata Steel 10th-28th Jan 2020

Unfortunately, that's not really the case. Please explain why it's not obvious what a watch cannot do. Pens as well. Put it this way, if an organiser tried running an event where participation was optional, a typical weekend tournament perhaps and tried banning watches and pens, attendance would be...

Have they gone too far with banning all watches?
Almost certainly. Banning headgear and earpieces makes sense as well if intending to thwart hidden communications.

Re: New grading conversions

Sure, that is why there is the "k" factor in the formulae, and it is precisely why I think grades should be calculated using historical data - because the process can calculate the k-factor as it processes the data... I do not believe the K factor on its own is sufficiently powerful to revalue rapi...

Re: New grading conversions

This would ensure most accurate ELO ratings. Elo theory relies to an extent on player strength being reasonably consistent and stable, neither of which is true when new players and juniors are involved. It's also necessary to fudge the issue of initial ratings a bit when starting from a clean boot ...

Re: Hastings Congress

The answer is that yes, he was, because it's the arbiter's duty to seek medical attention if the player turns out to be seriously ill. There was a case in India ten years ago. https://en.chessbase.com/post/should-one-wake-a-sleeping-che-player- https://en.chessbase.com/post/kolkata-open-inebriated-...

Re: Hastings Congress

the opening in Matthew Wadsworth-v-Roman Edouard from Rd. 7 (yesterday). 1. Nf3 c5 2. b3 d5 3. Bb2 f6 4. c4 d4 5. b4 e5 6. bxc5 Bxc5 7. d3 Nc6 8. g3 Benko Gambit reversed. Compare to 1.d4 Nf6 2.c4 c5 3. d5 b5 4. f3 White lost a tempo, so in effect took Black by playing b3 and b4, whilst an early de...

Re: FIDE Laws - An Interesting Case

I never worked out what would have happened if no such dawn had occurred and I reported the result as a draw while my opponent reported it as a loss. Hartston wrote about a similar event in one of his humour books, although I think there one player thought he had won and the other drawn. That suppo...

Re: World Rapid and Blitz Championships 2019

I expect many of us agree with your general thinking Increments make the premise simpler. If your flag falls you lose, unless there is no legal sequence of moves in which a mate can be demonstrated. That was the premise before quick-play finishes. When these were introduced British arbiters and con...

Re: World Rapid and Blitz Championships 2019

- but if a player wants to take the risk of regularly moving with 1 second left as Firouzja was doing then they can't complain when accidents like this happen. Despite the three pawn advantage, the final position is a draw according to a tablebase. So you can add the danger of playing for a win in ...

Re: World Rapid and Blitz Championships 2019

Any more than if the same thing happened when a player loses on time with an overwhelming material advantage. And you couldn’t write a law for that. There's 10.2/ Appendix G etc which enables the player with little time but an overwhelming material advantage to claim a draw. But that only applies w...

I was also looking forward to Jack hacking Roger. Maybe later.
Lifetime score is 4-1 in Jack's favour.

This has long been the case and tbh I am surprised that people are not aware of it.

There was an example in the recent past in the Women's World Championship where a win was awarded in King and Knight v King and Knight.
