Or just quietly make he bar point and be ahead in the race with both
runners escaped while she still has a checker on the ace point.

I'd expect that to be not much difference equity wise vs hitting and
running either back checker. And the bot play may be to slot the five
point, but I'll just make the defensive bar point here.
