Solution.

B1 connects the three stones outside, as shown by the exchange of W2 and B3. Now W4 and B5 are miai, so White has only eye at the side.

[Diagram]

Failure.

The usual block at B1 fails, because it allows the dual-purpose move of W2. It threatens capturing the three Black stones at B3 as well as making the second eye at W4.

[Diagram]

Failure.

B1 tries to apply the first-line large knight's move connection technique, but W2 to W6 captures one Black stone and lives.

[Diagram]

Failure.

B1 tries the other diagonal. However, W4 is sente and forcing B5 if Black insists on the kill. Now after W6 and B7, W8 can atari.

[Diagram]

Failure.

This variation does not kill either. The variations after W4 is left as a reading exercise.

Another attempt

While white cannot run, can she kill the black stones in the corner after this? Or is there a better option for her?
