CHESS(6) — Unix Programmer’s Manual
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 notation. 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

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.
