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 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.

[Diagram]

Variation - correct

One of the correct responses is throw-in at B3 to reduce eyespace. After B5, a and b are miai for black to kill.

(B3 at B5 also kills.)


Failure

[Diagram]

Failure 1

B1 is safely met by W2 - Black has no inside tricks. This secures the largest territory, though later Black a will be sente. W2 at b or c lives with less points, without giving the sente move at a.

[Diagram]

Failure 2

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

[Diagram]

Failure 2 variation

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

[Diagram]

Failure 3

White lives easily.

[Diagram]

Failure 4
