In Response To: Double 2's in a mutual holding game (Timothy Chow)

I played 20/18(3) 8/6 here. But the rollout slightly prefers volunteering a shot, with 20/16 9/7(2) first and Seth's play 20/18 9/7(2) 8/6 second. I can't fully explain this result but I guess that part of the point is that after 20/16 9/7(2), even White's hit-and-cover numbers aren't that good for her since she's still stuck behind a five-prime with two blots to clean up. So the blot is not really as bad as it visually appears.
