[Stick Rice]

Too many valid choices to do anything other than the KISS play.

X is ahead in the pip count already, so a big roll suggests racing.
The trouble is that no matter what X plays, there remains a lot of
contact. I'd go ahead and attack with 10/2* 6/2. For the final 2,
I don't see anything better than 10/6.

For a unicellular player like me you've got to keep it stupid, Stick.
I can rephrase the problem. Find the class of plays that is better than all others. That's where I went wrong OtB.

As Tim said, the point here is that whatever play you make, moving 2 checkers 10 pips or 2 points x 5 pips, if you're not hitting you're still facing contact. Hitting the blot strives to solve that problem.
