[Graham Banks]

The July 25th update of the CCRL Rating Lists and Statistics is available for viewing at:
http://www.computerchess.org.uk/ccrl/4040/

Our standard testing is at 40 moves in 40 minutes repeating and our blitz testing is at 40 moves in 4 minutes repeating, both adjusted to the AMD64 X2 4600+ (2.4GHz).

Currently active testers are:
Graham Banks, Shaun Brewer, Kirill Kryukov, Dom Leste, Tom Logan, Charles Smith, George Speight, Gabor Szots and Chuck Wilson.
Other team members are:
Ray Banks, Eric Lamar, Arnaud Loheac, Bill Rogers, Andreas Schwartmann, Joshua Shriver, Chris Taylor and Martin Thoresen.


During the early stages of testing, an engine's rating can often fluctuate a lot.
One should also 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.


Our 40/40 list usually gets updated during the week also and can be viewed here:

However, no game downloads are available from the live link.

The links to the various rating lists can be found just beneath the default Best Versions list.
For example there is a 32-bit Single CPU list.


Our latest 40/4 ratings can be found at one of the following links:

Our FRC 40/4 rating lists can be found here:

Only those engines that can play FRC through the Shredder Classic GUI are tested.


The LOS (likelihood of superiority) stats to the right hand side of each rating list tell you the likelihood in percentage terms of each engine being superior to the engine directly below them.

All games are available for download by engine, by month or by ECO code.
ELO ratings are now saved in all game databases for those engines that have 200 games or more.

Clicking on an engine name will give details as to opponents played plus homepage links where applicable.

Custom lists of engines can be selected for comparison.

An openings report page lists the number of games played by ECO codes with draw percentage and White win percentage. Clicking on a column heading will sort the list by that column.
