    I count 11 sots after breaking the bar point and X is in very good shape
    when missed. I'd it loose if there was something reasonable to do with
    the four. But as I"m not seeing anything along those lines it's 18/13
    18/14.

    With O's killer board, 18/14 18/13 apparently volunteers too many shots.
    See the variant below, where O's blot has been moved from X's 3pt to
    X's 2pt.

    XG 3-ply, XG 4-ply, and XGR++ all favor 18/14 18/13 here.
