FWIW, a 0-ply 0-ply rollout

What it's worth is not much. Because it's 0-ply checker. Because it's 0-ply cube. And because the JSD for plays 1 and 2 is only 1.5. Just recently I've seen a rollout where one play trailed by 2.0 JSDs after 200+trials, but was leading after 350.

The score (after 0 games) is: White 9, Blue 4 (match to 13 points)

Move number 3: Blue to play 56
