_M_o_v_i_n_g _t_h_e _p_i_e_c_e_s:


Black makes the first move, and players alternate until  the
game is over.  A player must make a move if possible i.e. he
may not pass.  A move is either a simple move or a  capture.
A  simple  move  for  a  black  piece  is a move to an empty
adjacent diagonal  square  in  the  downward  direction.   A
simple  move  for a red piece is a move to an empty adjacent
diagonal square in the upward direction.  If a  piece  makes
it  to  the  opposite  end of the board (its king row) it is
crowned and may move to any of the four squares adjacent  to
it that are empty.


_C_a_p_t_u_r_i_n_g:


A piece or a king captures in the  same  direction  that  it

moves.   A  capture is possible when one's piece or king can
jump over an enemy piece placed in a square  that  otherwise
the  capturing  piece  or king could move to, and land on an
empty square on the diagonal immediately beyond the jumped -
over  enemy  piece.   A  captured  piece is removed from the
board.  If after a capture the capturing piece  is  eligible
to  capture  another  piece, it must.  The only exception to
this rule is when a piece makes a  capture  and  is  thereby
crowned  -  then  it  must  wait  for  the  next turn before
capturing again.  In general, whenever there is at least one
capture  available to a player during his turn, he MUST make
one of the captures.


_W_i_n_n_i_n_g:


The game is over when during his turn a player  cannot  move
(either  because  all  of  his  pieces have been captured or
because he cannot legally move his remaining pieces).   This
player is the loser of the game.


_P_l_a_y_i_n_g _t_h_e _C_o_m_p_u_t_e_r _G_a_m_e:


As your pieces are black, you will be making the first  move
of the game.  Black pieces, black kings, red pieces, and red
kings are represented by "b", "B", "r",  "R",  respectively.
To the right of the game board is a numbered board.  To make
a move one enters the number of the square to be moved  from
followed  by  the  number  of  the  square  to  be moved to.
Cheating is not allowed, so moves will be accepted  until  a
legal one is entered. The game ends when either player wins,
or when the human player's patience is exhausted.  A  record
of  the  game (in standard checkers notation) is stored in a
file named gamerec.txt.
