Black’s sacrifice technique with 3 and 5 is the key. This provides the two other black stones an extra liberty that allows Black to win a local capturing race with 7–11.
Your comment just made me realise that the Japanese would say ‘kakae’ rather than ‘atari’ in this case. Researching a bit, the difference seems to be that a stone getting kakae’d cannot avoid getting captured.
Descent, connect, cut, atari, descent, atari, hane?
