    I hit and made my 4pt, thinking that I had to try to win going
    forwards, but XG prefers hitting twice, which is more of a "two-way
    game" play. Depending on the dice, X can try to keep hitting O,
    or try to escape. If the result is that O sends back a lot of X's
    checkers, then X can fall back on a backgame plan. It probably
    won't be a good backgame, but it will be better than if he has
    only four checkers back and a crunched board.
