STOCKFISH(6) STOCKFISH(6) NAME
stockfish - free UCI chess engine, to calculate chess moves SYNOPSIS
stockfish DESCRIPTION
This manual page documents the stockfish command. stockfish is an UCI chess engine, to calculate chess moves Stockfish is a free UCI chess engine derived from Glaurung 2.1. It is not a complete chess program, but requires some UCI compatible GUI (like XBoard with PolyGlot, eboard, Jose, Arena, in order to be used comfortably. Read the documentation for your GUI of choice for infor- mation about how to use Stockfish with your GUI. This version of Stockfish supports up to 8 CPUs, but has not been tested thoroughly with more than 2. The program tries to detect the num- ber of CPUs on your computer and set the number of search threads accordingly, but please be aware that the detection is not always cor- rect. It is therefore recommended to inspect the value of the "Threads" UCI parameter, and to make sure it equals the number of CPU cores on your computer. If you are using more than four threads, it is recommended to raise the value of "Minimum Split Depth" UCI parameter to 6. Opening book This version of stockfish has experimental support for PolyGlot opening books. For information about how to create such books, consult the PolyGlot documentation. OPTIONS
This program does NOT follow the usual GNU command line syntax, with long options starting with two dashes. SEE ALSO
Communication with UCI commands is documented by "The UCI Communication Protocol" in /usr/share/doc/stockfish/engine-interface.txt. AUTHOR

eleeye_engine - a chess program engine to communicate with its user interface SYNOPSIS
eleeye_engine is a command-line client for UCCI (based on UCI) protocol. It provides full support of basic UCI command, such as position, go, banmoves or bestmove and much more. DESCRIPTION
The Universal Chess Interface (UCI) is an open communication protocol that enables a chess program engine to communicate with its user interface. It was designed and released by Rudolf Huber and Stefan Meyer-Kahlen, the author of Shredder, in November 2000, and can be seen as a rival to the older XBoard/WinBoard Communication protocol. Like the latter, it is free to use without license fees. Customarily, UCI assigns some tasks to the user interface that have traditionally been handled by the engine itself. Most notably, the opening book is usually expected to be handled by the interface, by simply selecting moves to play until it is out of book, and only then starting up the engine for calculation in the resulting position. (UCI does not specify any on-disk format for the opening book; different UIs -- user interfaces -- usually have their own, proprietary formats.) Also, the user interface may handle endgame tablebases if the engine does not support it itself, although this is often better handled in the engine, as having tablebase information can be useful to consider a possible future position.
