In Response To: Rollout: I never know whether to attack or prime (Timothy Chow)

Thanks, Timothy. The difference surprised me. But I've made bigger mistakes. Here's a Gnubg rollout (cube turned, since with centered cube White has double/take after the 4-3 play):

The score (after 0 games) is: White 0, Blue 0

White	148
Blue	142
