There are three types of backgammon players: those that
can count, and those that can't.
BTW: it's "those who can count", not "those that can count";

I think of this as a containment position. O can jump out with a 6
but she is not at the edge of X's prime, so hitting is not particularly attractive. Jumping out might seem risky, but O's sixes are duplicated
to jump out and hit, and her midpoint is stripped. Putting a checker
on the 18pt improves X's outfield coverage in case O does jump out.
