    Even when you have two anchors, breaking one of them can expose you to
    an attack. But here, O has four checkers back herself, two of which
    aren't so easy to escape, and her own board is not so strong. XG says
    that X should take the opportunity to play 21/16, which increases X's flexibility and outfield control.

    It's only right to run because of the opp's blotted ace point. Bring that checker back into play remaining in the zone and it won't be.
