CCRL 40/15, 40/2 and FRC lists updated (10th April 2021)

[Graham Banks]

The latest CCRL Rating Lists and Statistics are available for viewing from the following links:
http://ccrl.chessdom.com/ccrl/4040 (40/15)
http://ccrl.chessdom.com/ccrl/404 (40/2)
http://ccrl.chessdom.com/ccrl/404FRC (FRC 40/2)

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.

The links to the various rating lists can be found just beneath the default Best Versions list (as in this screenshot). Specific 32-bit rating lists are denoted as such to the right of the default list in each category. The default lists contain the 64-bit engines.



Our 40 moves in 15 minutes repeating and 40 moves in 2 minutes repeating are both adjusted to the Intel i7 4770k (3.5GHz) using the Stockfish 10 64-bit benchmark.

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, Ray, Gabor and Sergio). Thanks also to Chessdom.com for hosting our website.

Igel 3.0.0 is ahead of Houdini 6 at the rating list. It's now in 3th place ( I don' t count the Stockfish clone Fat Fritz).

Congratulations to Volodymyr Shcherbyna and Dietrich Kappe.

Thanks for the tests of KnightX 2.61 and 2.7
I hope v2.8 will approach 2700 elo, I work for that

Congratulations to Volodymyr Shcherbyna and Dietrich Kappe.

It's not statistically significant yet to say that Igel is better than Houdini in 40/15. The elo difference between Igel 3.0 and Houdini 6.0 is only 3 elo, while the variance of Igel's elo is plus or minus 21 elo. More testing could easily bring Igel's elo rating below Houdini's elo rating, as it did with Slowchess 2.5 vs Ethereal 12.75 on the 40/4 ratings. And based upon the CCRL 40/4 tests, which have more data points than the 40/15 tests, I'm liable to believe that Igel is in fact still slightly weaker than Houdini.

I am NOT surprised to see such great result for Igel, it is one of the program that is making the fastest improvement
