NAME
       chess - the game of chess

SYNOPSIS
       /usr/games/chess

DESCRIPTION
       _C_h_e_s_s  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’ spec‐
       ify 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 pro‐
       gram’s reply.

FILES
       /usr/lib/chess      binary image to run in compatibility mode

DIAGNOSTICS
       The most cryptic diagnostic is ‘eh?’ which means  that  the  input  was
       syntactically incorrect.

BUGS
       Pawns  may  be  promoted only to queens.  The book of opening moves has
       disappeared.
