Demolito is a UCI chess engine

Demolito is a UCI chess engine.

As such, it is a command line program, which is not designed to be used directly, but instead through an UCI capable UI, such as CuteChess or Banksia, or c-chess-cli.

This is free and open source software.

UCI options:

• Contempt: This is used to score draws by chess rules in the search. These rules are: 3-move repetition, 50 move rule, stalemate, and insufficient material. A positive value will avoid draws (best against weaker opponents), whereas a negative value will seek draws (best against a stronger opponent).
• Hash: Size of the main hash table, in MB. Should be a power of two (if not Demolito will silently round it down to the nearest power of two).
• Level: The default value is 0, which means the level feature is off, and Demolito plays at full strength. Level 1 is the weakest, and 12 is the strongest (but still weaker than switching off strength limitation with Level=0). Note that Demolito becomes non-deterministic (on purpose), so that it will play differently every game, even if it reaches the same position.
• Fake Time: Use this in combination with Level feature, if you want Demolito to (pretend to) think, instead of moving instantly. Does not affect playing strength of any level, but makes game play more human friendly (ie. you can think on your opponent’s turn, as you would against a human).
• Time Buffer: In milliseconds. Provides for extra time to compensate the lag between the UI and the Engine. The default value is just enough for high performance tools like cutechess-cli, but may not suffice for some slow and bloated GUIs that introduce artificial lag (and even more so if playing over a network).
• Threads: Number of threads to use for SMP search (default 1 = single threaded search). Please note that SMP search is, by design, non-deterministic. So it is not a bug that SMP search results are not reproducible.
• UCI_Chess960: enable/disable Chess960 castling rules. Demolito accepts either Shredder-FEN (AHah) or X-FEN (KQkq) notations.
