Nack and Stick were astute to observe that while this is a pass AtS, it's a take for money and the rollouts below confirm this. That's not why I posted this (I had no idea that this was the case), but it makes the position more interesting than I thought. Doubled gammons are especially valuable in a short match, and that makes the difference here.

The score (after 0 games) is: gnubg 0, you 0 (match to 5 points)

Move number 3: you on roll, cube decision?
