NAME

       chess - the game of chess

SYNOPSIS

       /usr/games/chess

DESCRIPTION

       Chess  is  a computer program that plays class D chess.	Moves may be given either in standard (descriptive) notation or in algebraic nota-
       tion.  The symbol `+' is used to specify check; `o-o' and `o-o-o' specify castling.  To play black, type `first'; to print the board,  type
       an empty line.

       Each move is echoed in the appropriate notation followed by the program's reply.

FILES

       /usr/lib/book	   opening `book'

DIAGNOSTICS

       The most cryptic diagnostic is `eh?' which means that the input was syntactically incorrect.

WARNING

       Over-use of this program will cause it to go away.

BUGS

       Pawns may be promoted only to queens.

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.
