    13/11(2)

    This way I block his 6 and have lots of time to set up my home board
    before he has to crunch.

    Roughly even race so O will want to run off the anchor if she can.
    Which does a better job of blocking, the eleven or the seven point? I'm
    not sure, but if the dice go our way race-wise it will be easier to
    clear the thirteen than the eleven, so I'll go with making the seven
    point. Plus, making the seven lets me also make the three point. Should
    be worth something.

    9/7 8/7 4/3

    There are two plausible plays; 13/11(2) is the play that X would make
    if well behind in the race, and 9/7 8/7 4/3 is the play that X would
    make if well ahead in the race. In this position, X is still behind
    in the pip count after the roll, so 13/11(2) is indicated. See the
    variant for a "crossover point."
