Checkers rules
==============

There are two piece types in checkers which move and capture on
diagonals: checkers and kings. Checkers can only move/capture forwards
and get promoted to kings once they have reached the opponent's base
line. Kings can move/capture along all four diagonal directions.
Pieces either move from one square to the next or capture by jumping
over opponent's pieces landing right behind them on an empty
square. Captures are mandatory and have to be completed. If several
capture sequences exist the player is free to pick any of them. The
player with no legal moves loses the game. The score is the material
difference (checkers and kings both count 1). In case the winner has
fewer pieces, (s)he wins by one point.
