SYNTAX

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.
