 (;B[g9]C[Peter\: This is winning, because as Eric pointed out, the way that g9 is connected to i6 is analogous to a i6-h6-g7-g9 crescent (with the "gap" at g4 playing the role of the gap of the crescent). This means that Black can connect i9 to i6. ]

(;B[g4]C[Eric\:

I was worried about this.

I now realize it would be similar to what happened, but I would not get a ladder escape in the K1 corner.

oh\:  Also, Black would not have i6.
