In Response To: Cube action (David Rockwell)

I'm not sure I totally trust the rollout results. 9% gammons seems very high. It makes me wonder if GNU is playing the white checkers correctly. But, I am pleased that I was in the general vacinity of evaluating the position correctly. OTB, I thought for a long time, waited and got a take next turn after dance / makes 2 point.

The score (after 0 games) is: GNU_bg 1, user 0 (match to 7 points)

Move number 3: user on roll, cube decision?

GNU_bg	64
user	26
Position ID: 9XYbAAABAAACAA Match ID: cAngABAAAAAA
