There are several alternative sets of rules by which to play checkers, the
ones used in this game are based on the rules for American checkers
and British draughts.
The object of the game is to take all your opponent's pieces or place him
in a position where he or she can no longer make any moves.
Players shall take turns at starting the game.
The visitor shall start the first game.
Obligation to move
A player has to move, a player who can no longer move loses.
All pieces, men and kings, can move only diagonally.
Pieces can only move to adjacent unoccupied black squares
except when making a jump (see below).
Men may only move and jump forwards while kings may move and jump forwards
as well as backwards.
Obligation to jump
If one player's piece has the opposing player's piece as a diagonal neighbor
and the square behind the opposing player's piece is unoccupied the player
can make a jump and remove his opponent's piece from the board.
If a player can make a jump such player has an obligation to make a jump.
If after making a jump another jump is possible the player must jump again
(with the exception of pieces that have just been crowned).
Upon reaching the last row on the far side of the checkers board,
the so-called king row, a piece is crowned and becomes a king.
Being crowned ends the move,
a crowned piece may not continue with a jump even if possible.
The referee will step in to determine the winner, if during 20 moves
(10 by each player), only kings have changed position
(i.e. no man has moved forward and no piece has been removed from the board),
and there appear to be repeating movements. In such cases the referee will
determine the winner according to who holds the strongest position.
Kings being worth more and men closer to the king row
being worth more than those further away. In the event that both parties
are of equal strength the referee shall call a draw.
There are several rules which will not be enforced during this game:
A piece once touched has to be moved.
If you do not make a jump when one is possible you lose your moved piece.
A warning is issued after 5 minutes of inactivity if you do not make a
move within the next minute you lose the game.
It is prohibited to annoy or distract your opponent. This includes, but
is not limited to, making signs or sounds, pointing or hovering over the
board with your hands or other body parts, needlessly delaying your moves,
blowing smoke in your opponent's face or appearing at the table dressed
in a provocative manner.
Alternative version of checkers include such things as, men being
able to take pieces backwards, men not being kinged if they have to jump
on after reaching the king row and so called flying kings who can move any
number of squares diagonally. None of these rules are implemented in this
version of the game.
As the computer thinks ahead by several moves, it will be ruthless and
unforgiving of any mistakes you might make. However the computer's
predictive advantage is less in later stages of the game even though it
then thinks ahead a bit further.
Although the game is relatively difficult it can be won by normal human beings.
