Main line (6 at 3).
The sequence of
and
is the key. Note that if Black captures the three white stones, the group will get a second eye and lives.

Main line (4 at marked atone).
The rest is atari all the way.

Main line.
Which ends in a shunt after
. Ironically, the
stone appears to be at a very beautiful position but does not help White at all.
Variations

Variation 1.
If
, Black lives simply by atari at
and
.

Variation 2.
Same case.

Variation 3.
The jump at
will only cause the entire chain to be captured.
Failures
![[Diagram]](../../diagrams/49/5b2878444a2361c2926eaa456f21a833.png)
Failure 1.
The direct atari at
does not work.

Failure 2.
The sequence of
and
is wrong. After
, Black is dead.
![[Diagram]](../../diagrams/34/4fc66f8fdc6835a30fbd0c8c170d7b25.png)
Failure 3 (8 at 5).
The smart aleck move at
will only remove White's weakness.
