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

This position might benefit from a better rollout, but the bot's preference for hitting seems pretty clear. Qualitatively, it's clear what the tradeoff is. Hitting gains a crucial tempo and wins more gammons, but it also loses more gammons. In general, I tend to attack too often, but in this position I went for 10/6.
