In Response To: Early double 5's after opponent has escaped: 42P-52S-66B-55? (Timothy Chow)

Here I was seduced by the better distribution of 13/3(2), but it's apparently much better to prepare for a possible blot-hitting contest by making two points. If I had already anchored then 13/3(2) might be right (see variant below).
