C[Weak move. This is not a 3rd row escape, so does not connect h5 to the edge.]

C[Indeed, Black must reconnect, but not in a way that benefits White. Black has played the unique move that captures the entire area (near the 1-edge) for Black!]

C[e8 variation\: Note that e8 is connected to the k-edge. The connection to the a-edge is assured by the ladder escapes d3 and d5 (which make c7 a force next move) and the threat at c9.]
