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 left side.

[Diagram]

Failure 1

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 2

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 3

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 4

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

[Diagram]

Failure 5

B1 loses more points.
