How does Black kill? Where should 3' have been played?
This is the bookish answer and clearly White cannot make two eyes this way. Black just has to ensure that 3 reamins connected to his outer stones.
The next couple of diagrams investigate non-bookish replies by white.
Black has to cut at 3 otherwise white will manage to get two eyes here. This allows White to attempt to escape. If white makes one eye with 8 and 10, 11 prevents a second.
If white tries to run to the right, Black can push, jump and cut with him and prevent a second eye - unless white bumps into friendly stones before reaching the edge of the board.
Here is a question for you all - to which I don't know the answer. "Is it possible to for black to stop white before the edge of the board without permitting white an eye? Answers by email please."
If White 3 descends, he can make the comb group (well stronger than the comb because 5 is connected). Therfore he lives comfortably.
