The latest CCRL Rating Lists and Statistics (15th December) are available for viewing from the following links:

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, and Basti).
- Ray for the weekly updates.
- Jay Honnold for both the tournament viewer and for hosting Graham's live broadcasts.
- all engine authors.

40/15 and 15m+10s testing this week will include (with live broadcast given where applicable):
