Solution

[Diagram]

Solution

B1, B3 atari the two stones. If White connects at a, White dies in gote.

[Diagram]

Solution

After B3, a and b are miai, so the white group has only one eye.

[Diagram]

Variation - wrong

White might try to play hane at W2 in order to play W4 in sente. If black gives the usual answer, a and b are miai for life. If W2 is answered with B6 white would have a chance to escape at W5.The correct answer is to keep following on the second line with B5 or throw-in at B4 to reduce eyespace.

[Diagram]

Variation - correct

After the throw-in at B1, a and b are miai for black to kill.


Failure

Failure

One of the simplest refutation to the hane of B1 is W2. After W3 and B4, it is not possible for Black to play at a.

[Diagram]

Failure

The squeeze of B1 allows White to play atari in the direction of W2.

[Diagram]

Caveat

Atari at W2 is a mistake. After B3, White cannot play at a, so White is dead.

[Diagram]

Failure

White lives easily.
