In Response To: Middle game 64 (Ian Shaw)

I got a surprise when gnubg played 13/7 8/7. I would have quickly made a fourth point to keep White on the bar.

The rollout has the two plays as very close, with a jsd of 0.008 - exactly the difference between the rollouts.

The score (after 1 game) is: White 2, Blue 0

Move number 11: Blue to play 64

White	147
Blue	146
