Kyriaas: Just to make sure that I am getting this one right, the reason why putting any stone inside after D18 is because the opponent will die anyway so that would be wasting a turn, right?
caranthir: Yes, we should stop as soon as the opponent has a dead shape and can't connect to the outside either. But moreover here after D18D19, it's urgent to play a move like F18 that prevents the opponent from escaping outside.
