Since you’re here...

We hope you will consider supporting us today. We need your support to continue to exist, because good entries are more and more work time. Every reader contribution, however big or small, is so valuable. Support "Chess Engines Diary" even a small amount– and it only takes a minute. Thank you.

Here is a new CEDR chess engines ranking list. The Chess Engines Diary team has conducted extensive tests, evaluating over 900.000 games!
Engine analysis reports
Please note that this database has been "cleaned," and we have excluded games that lasted fewer than 10 moves from the list. 

Please note!
We recommend downloading these games now. In July, we will be cleaning the database by removing games from older and weaker chess engines. The next version will therefore be significantly smaller, but will include more games from the top engines.
