F8 or either of [h10,i10\] was a much simpler win.]
   ;W[i8]C[Eric\:

White should have foiled at h10. Then Black won't have a ladder escape.]
   ;B[k7]C[Eric\: Better F8. Black doesn't need anything along the K-edge.]
   ;W[j7]
   ;B[e8]C[Eric\:

This works, but F8 would be simpler and  avoids needing E7.]

This way, Black at least doesn't connect locally.]

If this sequence happens, then F10 either connects via F9 or defends a ladder with D11.]))
