What Colour is the Wind - Few Rollouts

These are the rollouts of the last set of positions I posted whenever. I am also working off my memory of what it said in the book so if I get something wrong, sue me =)

I believe the book said this one was DP.

The score (after 0 games) is: gnubg 0, Stick 8 (match to 25 points)

Move number 4: Stick on roll, cube decision?

Ditto on this one in the book, DP was advocated.
