CCRL 40/15, 2m1s and FRC 40/2 lists updated (02-03-2024)

[Graham Banks]

The latest CCRL Rating Lists and Statistics (2nd March) are available for viewing from the following links:

https://computerchess.org.uk/ccrl/4040/ (40/15 and 15m+10s)
https://computerchess.org.uk/ccrl/404/ (BLITZ 2m+1s)
https://computerchess.org.uk/ccrl/402.archive/ (BLITZ 40/2 Archive)
https://computerchess.org.uk/ccrl/404FRC/ (FRC 40/2)

Our 40 moves in 15 minutes repeating (including 15 minutes with 10 second increments) and 2 minutes with 1 second increments are both adjusted to the Intel i7 4770k (3.5GHz) using the Stockfish 10 64-bit benchmark.
All of our current testing uses AVX2 compiles where available.

Be aware that in the early stages of testing, an engine's rating can often fluctuate a lot.

It is strongly advised to look at the many other rating lists available in order to get a more accurate overall picture of an engine's rating relative to others.

The inclusion or exclusion of engines in our lists should not be taken as our group making a statement about their legality or status. Where there is controversy, it is usually mentioned in the engine notes.

Thanks to:
- all of our currently active testers (Graham, Gabor, Sergio, Basti, Shaun and another).
- Ray for the weekly updates.
- Jay Honnold for both the tournament viewer and for hosting Graham's live broadcasts.
- all engine authors.

Indeed.

Same picture on 40/15, although a tiny number of games.

CCRL solved chess.

Chess960 is better, it takes the books out of the equation.

Without any hard evidence, choosing a particular balanced book can give different performance to another balanced book, I'd guess as much as 10 Elo. It is pointless now testing these top engines in the traditional way !

Yet to do otherwise would skew and invalidate all of our testing.
There was a good reason why Stefan kept his UHO and main rating lists separate.

You clearly completely misunderstood my comment.
