Basic idea is this. One player feels the game is going to end in a draw,
so they grab draw rights. If the game ends in a draw, or they win, they
get half the points they normally wound for a win (their opponent gets
none). If their opponent actually wins the game after doing this, their
opponent gets 1.5 points for the win (and the player who grabbed draw
rights gets nothing).
You do not want to grab draw rights if there is a chance to win, because
you cost yourself half your normal score, plus give your opponent more
points if they win.+
