CHESS(VI) 11/1/73 CHESS(VI) 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 and is not required; `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 and the elapsed time in seconds. 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 has been known to cause it to go away. AUTHOR K. Thompson BUGS Pawns may be promoted only to queens.
