Solution

[Diagram]

Black lives

B1 is the vital point. Now a and b are miai for life.

[Diagram]

Continuation 1

If W2, B3 lives with a bent four.

[Diagram]

Continuation 2.

If W2 here, Black captures with B3...

[Diagram]

Nothing happens

...White's throw-in is futile.


Failure

[Diagram]

Bulky five

If White is allowed to play W2 (it really doesn't matter where Black plays first), then White almost fills with a bulky five and Black is dead.


Points of territory

[Diagram]

Resulting shape

After "Continuation 1" above, this shape results on the board. After W1, Black must defend inside - else White's cut at B2 is atari and kills. The final territory is 3 vacant points + 4 prisoners = 7 points.
