GNU vs XG walking in a prime

The purpose of the rollout is not to determine how to play 41 but to see how the two bots on equiv settings handle walking in a typical prime and finishing the game. As we can see, XG does just fine here.

The score (after 0 games) is: gnubg 0, user 0 (match to 1 point, post-Crawford play)

Move number 4: user to play 14
