Answer to Problem 166 (atari and hanekomi) White first ataris with 1 in Diagram 1, then wedges in with 3. After Black answers with 4, White throws in with 5, then ataris with 7. Black connects with 8 in Diagram 2, and White ataris again with 9 and 11. Black has to connect with 12 in Diagram 3, but, after White ataris with 13 and 15, the black stones can't escape.
