OtB I struggled - I couldn't decide and knowing that checker on the ace being anywhere else on the board it was a take I decided to pass. This quickly turns into a 2pt game with other opportunities to win.
The score (after 0 games) is: user 5, gnubg 4 (match to 9 points)
Move number 3: user on roll, cube decision?
user 116
