I thought that too, I've no idea how this works.
Perhaps Oxford 5 have agreed to be the "C Arbiter" team. In other words, they only play if there would otherwise be an odd number, thus avoiding triangular matches where possible.

I guess such games are of exceptionally high quality. Hence are their other such examples in World Chess?
The obvious example is 60 Memorable Games by RJF. Even by then it was unusual for best or memorable game collections to include losses.

There's a certain amount of material one can glean simply by Googling with other search terms
A Google search for Malcolm Barker chess comes up with the usual chess biographic information about his brief career in top level chess in the late 1940s and early 1950s.

Despite his minus score HD might still have picked up some rating points there?
23 if chess-results is correct.

Re: 22th European Team Chess Championship 2019

I'm sure there was a similar pseudo-Marshall innovation in the Lopez a few years ago but I can't quite remember what it was, let alone what happened to it Gaweski was the man the variation is usually named after, but others including a younger Carlsen played it. It ran 1.e4 e5 2. Nf3 Nc6 3. Bb5 a6 ...

Re: 22th European Team Chess Championship 2019

Nice game. Apparently 14.d4 giving the pawn back was needed. I'm unconvinced that engines give reliable verdicts in positions where Black gives up a pawn for initiative and structure, when asked for a quick verdict anyway. They usually mark down the main Marshall lines for example. But I'm getting ...

Re: ECF Grading Proposals

But when Sean looked at all the results in the grading system the stronger player was scoring (say) 70%. (The argument is similar for other grading differences and the winning % was always less than it should be.) My observation on this was "so what". For those scoring around 50% and assuming they ...

English Seniors 2020

I see from the ECF calendar that the 2020 English Seniors will move to Kenilworth Holiday Inn and takes over what would have been the May Day Bank Holiday weekend. So it's running from Thursday April 30th to Sunday May 3rd with an afternoon start on the Thursday and two rounds each on the next three...

Re: Don't Understand Grading Calculation

Is a grade of 0 supposed to represent the weakest person capable of playing a game under FIDE Laws, or a random move machine? Neither. Both the Clarke scale and the Elo scale were essentially arbitrary with one of the objectives being to avoid negative grades or ratings. Back in the day, they would...

Re: ECF Grading Proposals

For instance in 2009 3.9% were graded above 200 whereas 6.6% are now. The effect of having more of the world's top players taking part in domestic graded events presumably influences this. Gibraltar, the London Classic and Isle of Man for example. The recent Grand Swiss brings even more of the top ...

Re: Don't Understand Grading Calculation

Isn't this what used to happen before the central computer program took over the job of working out what a new player's grade should be? (Except there was then no iteration because there was no program.) Local graders' estimates were usually accurate to within 10 points or so, I recall. They could ...

Is there documentation of how the desired result was achieved, and why?
The archives of this site should cover it, in particular this very "Grading Debate" sub-forum.

It wasn't an issue that was ever put to the vote at an ECF Council meeting.
