    Sorry for not including any analysis or justification but 8/5*/3* for me.

    The normal thing to do in the early game is to fight for the five point,
    and when hitting from the eight, bring one down.

    But O has a strong board. Does that change things? I'm sure it does,
    but I'm not seeing a stronger play. The double hit seems playable as
    does splitting, but I'll go with 13/11 8/5*.

    If X hits then he should hit twice. It reduces return shots a lot
    and the 3pt isn't excessively deep in the board. But O has a better
    board and X's back checkers are getting primed. XG steps up both
    back checkers with 24/22 24/21. For comparison, see the variant,
    where O has her 8pt rather than her bar point.
