My gut tells me that slotting the four while knocking her off that
valuable point is better than abandoning the midpoint and allowing more
rolls for her to make an advanced anchor. My gut is often wrong BTW.

And with a ~20 pip race lead perhaps not hitting is the right idea, but
I'm not in the mood to bury a checker on the deuce point. XG does not
have moods, so perhaps that's what she will do.

I'll enter with the four (ahead in the race, so no need to hang back)
and hit loose on the four. bar/21 6/4*

6/4* obviously gives O more return shots, but I think that a more
important consideration is that bar/21 gives X a very inflexible
position. See the variant below.
