New Chess Engines Diary Ranking CEDR - 01.11.2026

-

 


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  • The new game database (as of August 1, 2026) has been cleaned of very weak engines, outdated versions, and engines released many years ago.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.
All 129.244 games CEDR 01.11.2026 download.

We already have the new Fritz 20 program - what does it look like and how does it work?

The purchase process for the download version on the ChessBase website took only 5 minutes. Downloading the files from the cloud was even quicker. The installation itself, which involved five large files, took maybe 7 minutes, including restarting the system and entering the serial number I received upon purchase. The start image for Fritz 20 has a strange mosaic of colors; perhaps I'll get used to it. As you can see in the second screenshot, the program interface hasn't changed much; only the icons are different (we've been using Fritz 17 until now). It looks nice, but it's no major revolution. The next two screenshots show engine management and the installation of the UCI chess engine (here, Cataphract 1.1). As you can see, there are no changes. Screenshot no. 5 shows the analysis of some position by Fritz 20 engines. The changes are minimal - it is still very legible. Finally, on screen 6 we have the engine tournament table generated by Fritz 20 . I think it is sti...
