Re: Tata Steel 10th-28th Jan 2020

If they're away from the board then you wouldn't think anything of it On the contrary, you can be suspicious if your opponent is absent. That's particularly the case at some of the 4NCL venues when there's an area where support teams can lurk. Was that not the problem with the Smart Watch in Telfor...

Re: New grading conversions

1850 is madness for a first result. Get the starting point right at 1150 please. :D I suppose the idea is to ensure a minimum rating for new players. I would be more concerned about under rating new players from outside England. But perhaps their FIDE or other Elo based rating would be imported as ...

Re: Tata Steel 10th-28th Jan 2020

This conversation has made it clear to me that actually, you don't know what these devices are. If I played against you, I could use a smartwatch to cheat quite easily and you'd be none the wiser until you ran the game through Stockfish afterwards. You would be looking at your watch more frequently...

I may be missing the point, but some players will be taking medication at fairly specific times.
Younger generations may have given up on watches because they carry phones all the time. But if you are in a phones banned environment like a chess tournament, that doesn't apply.

Re: Tata Steel 10th-28th Jan 2020

. Alex’s point was that sometimes organisers will opt for a solution (not allowing any watches as an alternative to having to check all of them) which allows them to concentrate on other things. It’s hardly an unreasonable position. That's where we disagree. I consider it unreasonable. What is the ...

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: 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...
