Solution

B1 leaves white no way to link up or make a second eye in the corner.

[Diagram]

White tries to link up

If white tries to link up with W2, she is caught in a connect-and-die.

[Diagram]

White tries to capture

If white tries to capture B1, then the atari at B3 prevents the first line connection in sente, so B5 can capture the two white stones and kill the group.

[Diagram]

White tries to capture two stones

If white tries to capture the other two stones with W2, B3 is atari so W4 has to capture, and B5 removes the second eye.

Note: If W4 at a, white dies in gote.
