 Chess Engines Diary Ranking CEDR - 01.10.2026

Here is the latest CEDR chess engine ranking. We would like to highlight a few new updates:
  • Calculate ratings – Chess Rating Studio Pro.
  • The new game database (as of August 1, 2026) has been cleaned of very weak engines, outdated versions, and engines released many years ago. However, the legacy database containing over 900,000 games is still available for download.
  • Due to the smaller number of games in the new database, we have reduced the minimum threshold for ranking calculations to 100 games.
  • The anchor engine remains Critter 1.6a, set at 3250.

Here is a ranking list TOP 20 chess engines, complete ranking lists on our website: RATING
