^C^1Knight Exchange

   "Knight Exchange" is a solitaire game that is simple to play but, like chess, 
is difficult to master.  In this game the board is a four by four grid.  Twelve 
markers, each representing a chess knight, are placed on the board, with six 
white markers placed in the lower right of the grid and six black markers placed 
in the upper left of the grid.  The object of the game is to have the white 
markers trade places with the black markers in the fewest possible number of 
moves, with each piece moving as a knight moves in chess.  

   As in chess, each piece can move two spaces forward and one space sideways 
("forward" and "sideways" meaning any direction except a diagonal).  To move, 
type the letter of the square that you are moving from and the letter of the 
square to which you are moving.  For example, to move from "P" to "G", press 
first the P key, then the G key.  Don't worry - the program won't allow you to 
make an illegal or invalid move. 

   If you get stuck with no possible moves (it can happen!) or you just want 
to take back a move (or moves), press BACKSPACE.  You can use this feature as 
often as you like, but it costs you a point each time that you do.  Enter "S" 
to toggle the sound on or off, and type ESC to quit (you will then be given 
the opportunity to restart the game). 

   Oh yes, a word about strategy.  Like chess, mastery of the game requires the 
ability and concentration to plan your moves in advance. Unfortunately, the 
authors are both terrible chess players and this fact became painfully obvious 
in our playtesting.  Our best (lowest) score was thirty-two.  We don't know what 
is the lowest possible score, but surely you can better our effort.  Good luck! 
(NOTE:  The lowest score attained by BIG BLUE DISK staff members during testing 
was sixteen.)
