In Response To: Playing against two high anchors #1 (Timothy Chow)

The trouble with playing against two high anchors is that they cover the outfield pretty darn good. I decided to pay now with 16/8 since it wasn't clear to me that I'd be likely to roll better next turn, especially if White managed to clean up her blots in the meantime. GNU 2-ply thought 16/8 was a 0.056 error, but the rollout reverses that verdict.
