FIDE do seem willing to reset a rapid rating in some circumstances. In particular, take a look at Praggnanandhaa's rapid rating . He was rated 1927 in September 2022 and 2587 one month later, despite not appearing to play any rapid games anywhere near that period. The ECF rating help pages imply tha...

The GM & IM sections are set up in Swiss Manager as team tournaments in which four teams of three players play each of the other teams three times. By default, SM assumes that in team tournaments colours alternate on successive boards, and this appears to be the problem with reporting of colours in ...

There are 1,119 IDs of the form 9xxxxx in the 1994 grading list downloaded from the ECF website. Of these, 5 are in categories A-C with the remaining 1,114 in categories D & E. There are zero such IDs in the 1995 and 1996 lists, with seven in the 1997 list. My guess is that the 9xxxxx IDs were inact...

The location of the javaw.exe executable can be set in the Other > Options > General tab.

The only way I found of restoring the Full Analysis Engine and Notation windows from within the Houdini 3 GUI was to use Factory Settings from within the View menu. However, this has the unfortunate effect of resetting all user configuration to the just-installed defaults. To be fair to ChessBase, I...

Northumberland won on board count.

Are the qualification criteria published anywhere? There is some discussion of the qualification criteria on this forum here and here . The original page on the ECF site (https://www.britishchesschampionships.co.uk/qualifying-regulations-2020) is no longer available, but it is archived on the Wayba...

Looks like a browser cache issue. I was seeing V1-2 of the tournament regulations, but pressing Ctrl+F5 (to refresh the cache in Firefox) brought up the newer V1-3.

We know they hold the first of those (because we can see it while playing and afterwards) but we don't know if they use it in their analysis or deliberations. Do we know the other two? The lichess privacy policy states that they capture "the number of times the game’s window loses focus" and that t...

There is WFM Viktoria ZAJTZEVA scoring 276 if both Zs are scored.

Among untitled FIDE rated players, there is the almost palindromic Vladimir VOZHZHOV scoring 288.

Matthew, I was just making the point that an event which appears very unlikely can be made much more plausible by a moderate shift in our assumptions. The 3045 rating for a 2245 player is only as high as it is because the test sample size is so small (5 or 6 games I assume) and hence there is signif...

Suppose chess player Knightie McKnightFace plays six tournaments a year and has a stable rating... A stable rating is the key assumption, but suppose that Knightie has had more free time available recently and has been working much harder than usual on their game. As a consequence their playing str...

Yes, so long as the tool knows that you're in known theory..... Which must be a genuinely very difficult task these days. True. I remember playing the following line against Francis Rayner at Scarborough in 2015. [Event "Scarborough Open"] [Date "2015.10.25"] [White "Walker, David"] [Black "Rayner,...
