About This File

Written in "C", in 2014 for the Commodore 64 and ported to CX16 in 2020.  I wanted to know how hard it would be to make a chess AI.
I am not a great chess player, nor did I research chess engines, so I made things up as I went.  The end result is this chess 
which by any standards of chess, is not a good AI opponent.  However, it's there and it's playable.

Use and keys

The user controls an on-screen cursor.  The cursor changes color to indicate
a state.  The colors for selection are:
  Green - the piece can be selected
  Red - The piece cannot be selected as it doesn't have valid moves
  Purple - Empty tile or piece on the other side
  Blue - The currently selected piece
  Cyan - A valid destination for the currently selected piece

To move the cursor, use the cursor keys.  To select a piece, press the RETURN
key while the piece is selected.  To deselect the piece, press RETURN on the
same piece again, or press ESC.

To bring up the menu, press the M key, or the ESC key when no piece is
selected.  Pressing ESC in a menu backs out of the menu, to the previous
menu or back to the game.  Press RETURN to select a menu item and use the up
and down cursor keys to change the selection.

While a side is under human control, there are a few more options.  Press B to
toggle on/off a state showing on every tile how many of both black and white's
pieces can attack that tile.  Pressing A will toggle a highlight of all of the
pieces on the opposing side that attack the selected tile.  Pressing D will
toggle a highlight of all the pieces on the side currently playing's side that
can defend the selected tile.  All three of these options basically give a
visual representation of the Game Database.  The colors are: For attackers Cyan
and for defenders Red.

Lastly, the game has an Undo/Redo stack that tracks the last 254 moves. Pressing
U will undo the last move and R will redo the last move.  In an AI/Human game,
the undo will undo the last AI and human player move, so the human player can
make a different move.
