Cube: 1
X on roll, cube action

This position is worse for O than the previous position. X has 11
checkers in the zone, and a three-point board. O's chances of
anchoring are worse since she has only one checker in X's board
to anchor on, and it's on a high point that could get whacked
immediately. The pip count differential is also pretty large. The
one thing O has going for her is that she's made her 5pt. I thought
it wasn't enough for a take, but XG says it is plenty.
