In Response To: Attack or Anchor? -- Rollout + Variants (Terrapin)

I don't think it's so much about infinitesimal changes in race, otherwise moving the 9pt back to 10pt would make hitting stronger, but instead it goes down in value dramatically compared to the OP. I think your variants show that having the 10pt, which is exactly 6 pips away from the white blot, is a lot more effective in blocking the blot compared to having 11pt where it would be easier for white to escape and so hitting goes up in value if it's going to be more difficult to contain the blot.

Here is another variant for you, improved distribution of white's spares clearly points to anchoring despite our race getting 5 pips worse.

White is Player 2 score: 0 pip: 152 Unlimited Game Jacoby Beaver pip: 153 score: 0 Blue is Player 1 XGID=----a-EbCB--cC---cAd-b--A-:0:0:1:42:0:0:3:0:10 Blue to play 42
