I would probably hit 8/3* 6/3. I think we need to put O on the
defensive and take away one of his dice from being used for building
anchors in the outer board.

Good problem. I'll point on her head here since that's my nature. Won't
be surprised if making the five is the bot's choice.

Might 23/18 6/3* be worth a look? Certainly worth a look, but too loose
for my tastes.

If X hits, what is he hoping to accomplish? He's not well-positioned
to contain O's checker---he doesn't have much ammunition and O has the
better board. X should have plenty of time to build his board and play
a normal holding game since O still has 6 checkers on X's side of the
board.
