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.
