The text says, Black´s play only helps if the ladder on a works...
Is it not sufficient to create a loose ladder here for capturing the cutting stones (if White does not want to give up the right side), since the marked Black group has enough liberties? SvenB

I see...thank you. SvenB
Black to play and win.

Interesting exchange?

Interesting exchange? (I)
Interesting exchange? (II)
Interesting exchange? (III)
Interesting exchange? (IV)
What about this one as an answer to the marked white stone? (Leads to the original solution, admittedly :-) SvenB
