Stockfish made huge waves earlier this year when the release of Stockfish 12 pushed computer chess to new Elo heights. Stockfish remains the premier chess engine on the planet on this update, topping all rating lists—bullet, blitz, and rapid.

The most exciting new development in the prior month of the Computer Chess Championship was the release of Dragon by the Komodo team. This NNUE engine had a strong debut, performing well in both rapid and blitz, coming in just behind Stockfish and Leela Chess Zero on the monthly blitz rating list. Dragon also earned lots of fans for having one of the best logos among the top chess engines.

November focused on two premier events in the Computer Chess Championship—the "Mystery Engine Debut and Tuning" round robin which was Dragon's coming out party and the ongoing "CCC Blitz Championship 2020" which is now in the semifinal stage.
