    The blot in the opponent's home board is a juicier target, but 23/20*
    hits only once while 6/5*/3* hits twice, and both of those blots are
    on points where O would like to anchor.

    X us way ahead in the race, so hitting in his homeboard is probably anti-positional, even if he hits two. OTOH, X doesn't want O to make a
    second anchor, so 6/5*/3* might be the right idea.

    But I'll make the prosaic play of 23/20*. More to get the runners
    moving while she's occupied getting off the bar than to send a fifth
    checker back.

    And also we can always hit the blot on the 20pt later since the opponent has two on the bar and nearly no matter what he does won't have a real chance to cover it for multiple turns.
