I made the golden point and a solid five-prime with 24/20 9/7. What's
not to like? Well, O's straggler is at the edge of the five-prime.
The alternative, 24/20 11/9, leaves a direct shot but threatens to make
a six-prime. XG says it's well worth the risk. If O fails to hit right
away, then X has a strong cube.

If O already owned the cube, then XG would still favor 11/9 over 9/7,
but by a smaller margin.

Making the GP and the bar point seems obvious. Maybe the aggressive
11/9 7/3* is better, but the other play leaves a position that looks
more "pretty". I'll do that.
