    Yes, hit, of course, but which hit? Hitting twice seemed too loose to
    me given O's four-point board, but that's what XG insists we must do.
    We have a four-point board of our own and O will be twice up, so even
    if she hits back from the bar, we may still end up on top.

    Catching up....


    X will be ahead in the race after hitting, so the game plan would be to
    win by running. 22/14* seems to accomplish that best, although the
    double hit of 13/11* 8/2* is tempting.

    22/14*.
