The rollout for Karol's original position is copied above.

Contrasting his original position, Karol offered an instructive variant. I had rolled out one similar (with the 4pt made with 8/4 6/4 instead of 13/4 6/4) -- no need to reproduce it here.

Below is another variant. White has made her 9pt with 13/9. With this stabilization, she again discourages Blue's 62D (comes in fourth place).
