W1 puts a black stone in atari. The only defence for Black is to set up a ko at B2.

If B2, White connects underneath at W3. Black is totally dead.

[Diagram]

Variation 2.

Same as variation 1.

[Diagram]

Variation 3.

B2 prevents White from connecting W1 to the exterior stones, but W3 kills Black easily.
