    I'd say Double / Drop.

    Other than getting a couple large doubles, O is in a precarious
    position. It's doubtful he would hit in his inner board so even if X
    can't get out now he's probably safe there. Live to fight another day.

    O's takepoint AtS is an elevated 40%. She probably has that now, but if
    X springs the runner and isn't hit she won't. So, enough market losers
    to ship it and definitely a cube against a human since some will pass.

    O is 24 points behind in the race, and I cannot see many pluses in its position, I do not believe it has 40%. I would rather pass
    Anyway OTB I agree, many players would rather pass than define the match this time

    Does O have 40% winning chances here? I thought so. She has a
    four-point board and X still has work to do to bring his two
    stragglers home. Admittedly O has dead checkers on her 1pt, but
    X has semi-dead checkers of his own. Nevertheless, XG believes
    that this is a pass. But it doesn't require that much tweaking
    to turn this into a take (see variants below).
