    O's weak board invites a bold play so slot the nine point. Either we
    make that next roll or we get hit and have a shot at O's homeboard blot.

    16/9.

    Ah_clem had the right idea here. Making the back of the prime would be
    huge, and O has a blot in her board.

    Even without the blot (lift it to the 6pt) it's still correct to play to the 9pt.
