CCRL 40/40, 40/4 and FRC lists updated (21st December 2019)

[Graham Banks]

The latest CCRL Rating Lists and Statistics are available for viewing from the following links:
http://ccrl.chessdom.com/ccrl/4040 (40/40)
http://ccrl.chessdom.com/ccrl/404 (40/4)
http://ccrl.chessdom.com/ccrl/404FRC (FRC 40/4)

Our 40 moves in 40 minutes repeating and 40 moves in 4 minutes repeating are both adjusted to the AMD64 X2 4600+ (2.4GHz).
However, our testers use different hardware ranging from an Q8200 through to the most recent i7's and octals. We benchmark our hardware for consistency of results.
These time controls are roughly equivalent to 40 moves in 15 minutes repeating or 40 moves in 1.5 minutes repeating on modern computers.

Please note that the three lists are often updated separately to each other. The FRC list is only updated when a new engine or engine version is being/has been tested.
Also, please note that the 40/40 and 40/4 lists are constructed from totally different databases and not comparable to each other.

Thanks to all of our currently active testers (Graham, Ray, Gabor, Sergio and Volodymyr). Thanks also to Chessdom.com for hosting our website.

Thanks for testing Invictus!

Invictus r305 64-bit - 2915
Invictus r228 64-bit - 2256

659 Elo! Not bad for a 2 months part time effort. Hopefully it will catch up to Hannibal in the near future!

It's a combination of eval and search. It is easy to add new eval terms as it can be easily tuned. Search parameters though is another story. This is where lots of improvement can be made in the future but will require more testing resources.
