CCRL Rating Lists and Statistics (5th September 2026)

Post by Graham Banks »

The latest CCRL Rating Lists and Statistics (5th September) are available for viewing from the following links:

www.computerchess.org.uk/ccrl/4040 (40/15 and 15m+10s)
www.computerchess.org.uk/ccrl/404 (BLITZ 2m+1s)
www.computerchess.org.uk/ccrl/402.archive/ (BLITZ 40/2 Archive)
www.computerchess.org.uk/ccrl/404FRC (FRC 40/2)
www.computerchess.org.uk/ccrl/Chess324/ (Chess324)

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:
- Kirill Kryukov who wrote the scripts that produce all CCRL data, with recent processing speed-ups from Martin Sedlak (Cheng author).
- all of our currently active testers (Graham, Gabor, Basti, Andres, Naman and Mark).
- Jay Honnold for both the tournament viewer and for hosting Graham's live broadcasts.
- Jonathan Gilchrist for the utility CCRL notifier, which alerts engine authors when their engine is playing in a live broadcast.
- Anton Mihailov (Chessdom.com) for hosting our rating lists for many years.
- Sam Roelants (Simbelmyne author) who has taken over the hosting of our rating lists.
- all engine authors. Without you, CCRL wouldn't exist.

40/15 and 15m+10s testing this week will include (thanks to Graham, Andres, Naman and Mark). Live broadcast given where applicable):

Live broadcasts of some Gauntlets can be made available upon request.
