In this repository we maintain the current submissions to important computer chess tournaments like TCEC or CCC.

Older submissions are archived as well, if you want to replicate a specific version of LCZero used in a particular tournament.

New submissions should include:

• A json file specifying the name, command and parameters of the engine in a cutechess-cli compatible format.
• A build script which downloads/updates the source code and builds the engine.
• A README.md file containing additional information about the tournament parameters (hardware, time control, openings, opponents etc).
• (optional) Additional benchmark data provided by the tournament organizers.

The goal of the root level configurations is to always have a semi-recent and stable configuration ready to use. Experimental configurations should therefore only be submitted as pull requests with the goal not to be merged.
