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.
