NAME

Games::Chess::Referee - work with chess positions and games, according to the rules of chess.

SYNOPSIS

    use Games::Chess:Referee;
    new_game();
    ply('e2e4');
    ply('e7e5');
    show_board();
    move('d2d3', 'd7d6');
    show_board();

DESCRIPTION

The Games::Chess:Referee module provides a mechanism to interpret (almost) standard algebraic chess notation and to print out the resulting positions. It makes use of the Games::Chess::Position and Games::Chess::Piece classes by Gareth Rees, adding the chess rules and move application functionality.

ERROR HANDLING

Where the code does complain, it uses the carp routine. The ply() and move() routines return zero on failure, one on success.

LIMITATIONS

In this very early version, many of the rules of chess are not yet implemented. The code is in a state of flux right now, as it is being reworked into a class from a simple afternoon proof of concept. See the README file and comments in the code for more information.

BUGS

There are no known bugs as of this writing, but it would be reasonable to consider the limitations as bugs.
