Gnu Backgammon vs. Snowie Openings, Part 2

Gnu Backgammon and Snowie are both very strong, but in about 15% of responses to the opening roll, they disagree with each other, or with rollouts. Let's continue our survey, using long Gnu Backgammon rollouts as the referee. Again, I won't mention every interesting decision, but if I skip a decision, you can assume that Snowie 3-ply and Gnu 2-ply evaluations agree with long rollouts.

A Puzzle

First, something unrelated. I'd like to point out a puzzle which reminded me of backgammon, and of the Rolling Pigs game played at some backgammon tournaments. This is problem #232 from the Project Euler site. This site has programming exercises with mathematical themes. Almost all of the problems require some programming in addition to mathematics.

Very nice survey of opening replies, thanks Doug!

PS

What is meant here?

"Given the choice of playing 24/18 and 13/7, I almost always choose 13/7, but unstacking is sometimes right."

I for my part almost always split and tend to overlook a bunch of the correct unstackings.
