Surprise: Obsidian dev-14.23 SE wins 1 League CEDR Season 01/2025

-
The first edition of the CEDR chess engine league this year has begun. The 1st League has ended and there is already a surprise - the Obsidian dev-14.23 SE engine won. The Stockfish dev-20250106 engine scored the same number of points, but had a worse Bucholtz auxiliary score. In 3rd place was the Dragon 3.3 by Komodo engine. The next tournaments promise to be just as interesting - results will be available on our website soon.

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.

Finally, on screen 6 we have the engine tournament table generated by Fritz 20 . I think it is sti...
