I did a search of my competitive standardplay games since 2000 (slightly over 1000 games) which found 6 games where a double check was made. So I can at least say they are not very common in my games!
EDIT: In no cases did the double check deliver mate.
Search found 90 matches

Re: Happy Birthday IM James Sherwin (25-x-1933)
If you want obscure then I will offer Roelof Westra. No longer competing, but still occasionally imbibing :) Never played him but have "seen him around" at congresses in the past - when did he play RJF? (chessgames.com has just one 1980 game for him) I've just noticed this thread. Roelof is not obs...

I realised a few minutes after posting this though that "various" is debatable as two games I was thinking of were played by Duda.Eric Gardiner wrote: ↑Mon Jan 25, 2021 8:46 amBh6/...Bxa3/...Bh3 sacrifices have been played by various players - Shirov should be pleased!

Re: Wijk aan Zee 2021
In Anton-Tari it's remarkable that a zugzwang that wins for Black appears to have been missed in an endgame White was trying hard to win: 54...Bb5. Presumably the idea which I've checked for a few seconds with an engine running is: 55.a4, Ba6; 56.a5, Bb5; 57.h5, Kg7 and Black stops the kingside pawn...

Re: my favorite but unusual line of the Lopez exchange for Black
I imagine it would occur quite a lot in online games? Checking on Chessbase's online database, I found several 2200+ players who have played 5.Nxe5. A couple of the games look like pre-arranged draws however.

It will be interesting to see the age profile of the of the players - my guess is that those still at school will be more tolerant of the conditions!

Re: Cheating in chess
Justin, I know there are certain number of bans overturned and this would appear to be an example where a player could relatively easily argue their case. A human would look at the appeal and I imagine the opening theory aspect would be easily verifiable, so I would have thought an appeal could wel...

Re: Cheating in chess
Another feature that often irritates is the tendency to be told that "letting time run out rather than resigning" can lead to a temporary suspension. I have been given this reprimand several times, none of them occasions where I had deliberately let time run out, but simply had very little time lef...

Re: 4NCL On-Line Congresses
Possibly because there are more alternative online events starting up. I've stopped playing online (although not because of my age!) so can't really assess whether this is true. However the 4NCL Online congresses do charge an entry fee so if there are comparable tournaments that players can enter f...

Re: Perhaps you aren't a number and are a free man but OTB so many revert to the former inadvertently.
I agree ratings and their importance have been overrated(!) but they are needed to give a very rough guide in team selection and pairings. And ... when OTB congresses were taking place, I suspect many players hoping for prizes in grade-limited sections would have complained if forced to play strong...

Re: New ECF Rating Database
The new site looks very good to me and the information provided and search facilities appear more extensive than those on the old Grading site. I wonder if there are any plans to allow users to make more complex searches? An example would be to find all players named Smith rated between 1600 and 169...

Re: Club Membership & ECF Membership Fees

Re: Club Membership & ECF Membership Fees
Yes Mick I think so. Do you know the answer to my question? My question was more of a practical one rather than a direct contribution to the discussion of the current health risks of playing OTB chess. I did quickly put one of the links into Google Translate but didn't spot anything about whether yo...
