but if 'plain dodgy stuff' with questionable move matching rates is erroneously included is this really going to have a huge impact on the test result? What I am thinking is that if only games played where both players are above 2300 are included, there's whole areas of opening theory that players ...

When the the full test is performed all theoretical moves ( as defined by moves played by 2300+ players) are removed, so things should look a lot better for John. Of course, if John has done lots of computer analysis and expanded on existing knowledge, remembering lots of lines with all his opponen...

Can we assume there was no increment?

If there wasn't an increment, why wasn't the player with the Rook able to invoke 10.2 or one of its successors before the flag fell?

but perhaps something will be organised before then.

If he's resolved his differences with the local Malta federation, perhaps the Sniper will pop up with something.

Is there some allowance made for opening preparation being made in events which have moved from otb to online, particularly where long time controls have been retained? They claim not to check "book" or "theory" for engine matching, but as with much of the process, there isn't much disclosure of th...

(page 142 explains a caterpillar display)

The closing dinner at the London Chess Classic used a variant on that theme.

then presumably it would be open to an aggrieved party, if deprived of a prize to which he or she felt rightfully entitled, to sue for breach of contract. In England the Small Claims Court route might be used. It's happened. The organisers of a tournament accepted the entry of a previously graded p...

I wonder how many claims based on loss of castling or e.p. rights ever actually come up. There was an example at GM level in the 1980s between Karpov and Miles. One of them started a repetition sequence with something like Ra1-a5 followed by a retreat of the Rook back to a1. The draw claim was reje...

I suppose it's unkind to speculate on how arbiters are expected to have "meaningful information about the logic involved" in the decisions of Lichess and Chess.com, to name the two most obvious cases, when those platforms won't disclose that information. I suppose the paragraph in the FIDE Handbook...

Ponomariov has linked to this

The linked game starts 1. d4 e6 2. c4 Nf6 3. Nf3 Nf6 4. Nc3 a6. The first seven half moves have a "book" flag, but not the eighth. If they are starting the engine detection at 4. .. a6 they will get misleading results.

Naturally this leads to the conclusion that the processes used are therefore not free of flaws and innocent players may well be getting chucked out of tournaments and having their reputations trashed as a result of this. I thought it was known that the statistical methods used can throw up false po...

I asked Eales how Philidor's experience of the British authorities on arriving in London as an asylum seeker in 1793 compared with the more recent experiences of Mihai Suba in 1988 and Shohreh Bayat in 2020. I don't know whether 1988 counts as history yet. Perhaps it does if the fall of the Berlin ...

I must confess that I've always wanted to play the Scarborough tournament, but it always clashes with something else.

It's around the same time as Guernsey. Any news on plans for that?

the Div 3C have 4 in Leamington Spa, plus Daventry

For some 3S teams and players, there won't be much to choose between those and Milton Keynes/Maidenhead. I'd rather expected 3C to have Telford as one of the venues.

No direct chess references, but a couple of paragraphs caught my eye as things that arbiters of on-line play might find desirable. https://www.theguardian.com/business/2021/mar/26/teleperformance-call-centre-staff-monitored-via-webcam-home-working-infractions According to documents and video, at ran...
