AVAILABILITY

This game is available for Sun-3 and Sun-4 systems with the Games software installation option.  Refer to Installing SunOS 4.1 for information on how to install optional software. 

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. 

DIAGNOSTICS

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