Here's another case where Magriel's safe/bold criteria induced me to
play the safe 11/4. However, X is the underdog and should be willing
to take some risks. This is shaping up to be a priming battle, and
slotting 8/5 has a very big upside if X is missed, especially since
that ugly stack of 5 checkers in the 8pt isn't doing much for X.

Even after seeing this rollout, I was surprised to see that the XG
rollout favors slotting even in the variant position below. (In this
variant, XG 4-ply favors the safe 11/4.)
