CCRL 40/15, 40/2 and FRC lists updated (6th March 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.

Just have a simple question, you do NOT test LC0, Alliestein, and Stoofvless in FRC because you do NOT have their FRC Nets whereas TCEC have them for those Engines https://tcec-chess.com/live.html

Just have a simple question, you do NOT test LC0, Alliestein, and Stoofvless in FRC because you do NOT have their FRC Nets whereas TCEC have them for those Engines https://tcec-chess.com/live.html

A simple answer - because testing GPU engines is a total pain in the arse. No concurrency, even if you had a machine with dozens of cores you can run only one match. Not to mention the thousands of different nets available, which do you choose ? Not to mention choosing the "right" GPU. And yes, given all of that, no incentive to buy a Net. We certainly did run a few thousand FRC games with Lc0 and Allie, and they were on the list for a while. But we then made the decision to discontinue. Same with 40/15, we did test for a little while there too. Even harder there with the longer time control. There was no point leaving old versions there so they were removed. Below is an FRC screenshot before they were removed.

The standard blitz list is our only list with GPU engines. Not saying they won't return to the other lists, but it is unlikely.

So probably your site CCRL could be the first to test the 10 best engines on your CCRL List, but playing with Kramnik's No Castling Chess It should be very easy under most GUI by simply turning off the castling for both sides especially under Arena ? We could learn easy by observing the top 10 engines, which are the best Openings with White and with Black Pieces playing with NO Castling rule.

I haven't really heard of that, what is the point of it ?

Personally I don't use Arena, only Cutchess GUI.

I checked on Cutechess GUI it also has the same capability of turning off castling for both sides

I just experimented under Cutechess 1.0 and wanted to know how Komodo 13.3 vs Komodo 13.3 would play a Non Castling game, well here it is

I don't see anywhere in CuteChess GUI where you turn off castling, but this is an engine feature surely - if the engine wants to castle, then it will, nothing you can do to stop it. How can a GUI tell an engine not to castle ? You still use an opening book, or not ? Books may contain castling moves. I still see no point in this.

Here, I use PGN to not castling.

Ng8 8. Nb1 Nb8 *[/pgn]

[Modern Times]

So you need a special openings pgn with a sequence of moves that precludes subsequent castling ? Again, what is the point of this ?
