How to capture here?
I’m not very good at life and death problems but I just cannot figure out how black here captures. The puzzle says correct but I only see options:
N14 (black), M15
Then a net on L14 but white can play O14 and black cannot save those stones. Without the net black can start a ladder (M14, K15, L15) going to bottom left but since we don’t know what is there that doesn’t sound like a good solution. There must be something I don’t see.
Solved - it is the ladder and assuming empty board.
