Rollout: Which bar? #6

In Response To: Which bar? #6 (Timothy Chow)

I reasoned as follows: In a mutual holding game it's usually advantageous to secure the more advanced anchor (unless you're clearly behind in the race). Priming the opponent's advanced anchor is less urgent strategically. Though I think this line of reasoning is generally sound, it doesn't quite apply here because:

1. tactically, making the 18pt gives the opponent too many good rolls;

2. priming increases in value when the opponent has a straggler as well as an advanced anchor;

3. we're not really ahead in the race, so securing the more advanced anchor is less urgent.
