    I wouldn't. I think O is in trouble unless he gets 22, 44, 55.

    Let's try shifting home board points. 6/1, 5/1.

    Playing 10/6 10/5 avoids wasting pips in the race, but gives up on
    getting a double shot if O is forced to break anchor next turn with
    61 62 64 65. In fact X might even be able to wait one more turn to
    get the double shot.
