CHESS ENGINE OLYMPIAD. EDITION II

The tournament consists of two phases: the first consists of qualifying tournaments of each country, where the four best engines are classified directly for the team of your country. Depending on the number of engines participating and the final number of participating countries, there may be some "B" or "C" teams from some countries, so that up to 12 engines could be classified in some countries.

The qualification tournaments will start in alphabetical order of each country, running three tournaments each time, until they finish all.

Once all these qualifying tournaments are finished, the second phase will start, a Swiss system tournament with 6 rounds probably (it will depend on the number of teams)

Engines

Open to all Winboard and UCI engines (free, private and commercial).
Engine authors can either post their wish for their engine to participate or contact through email (sergiomg24@hotmail.com) or private message. I will choose engines by myself too.
More than one engine by author is allowed.
In case of having more than one author of different country by engine, I will assign the country (team) in which they must play by choice of their authors. If there are no preferences of its authors, I will assign the engine to the country with the fewest engines.
Updates will not be allowed during each tournament (before qualifying tournaments start and before main swiss tournament starts).
The similarity tool will be used to determine whether or not an engine can participate (Engines allowed until 70% of moves match).
Results will be rated only for engines already in the CCRL lists.

Deadline: January 22

Start: January 23
