Better e10. This gives Black only one ladder, and at height 3, rather than 2 ladders at height 2.]

Black should not have let White foil here.

(Maybe Black felt that Black needed to hope White made a mistake here.  However, White is not as strong along the K-edge as H6 might make things seem, since White won't get an escape from the K11 corner.

See variation.]

Black can still get a wall here, although it won't be as good of a wall. See next variation.]

This both is a peep and is in the middle of a U-turn.

Alternatively, Black can build a wall here, and then bring play to the A-edge.]

G9 is close-enough to Black's edge that H6 connects via a ladder to E10.]
