C[Eric\: This is an advanced comment. i5 settles the k11 corner. After it, j5 may-as-well be white and e10 may-as-well be black. (After seeing that White has a virtual connection, e10 comes from analyzing similarly to a cavern, but using that White can't allow j4 to connect to the 11-edge.)

C[Eric\:

Since Black can still play G9, this won't matter here, but more-locally, K7 would result in Black only escaping height-2 ladders.

j9 is better because it also escapes height-3 ladders.]
