Analysis

There is an eye at a. If Black can connect the BC stone back, then White will be dead.



Solution

[Diagram]

Solution

The blind spot is B1. Now White cannot capture the BC stone.

[Diagram]

Variation 1

If W2 blocks, then B3 captures the White group including W2.

[Diagram]

Variation 2

When W2 clamps at the BC stone, B3 connects the BC stone to the outside stones. Due to shortage of liberties, White cannot play at a.

[Diagram]

Variation 3

The diagonal move at W2 is an interesting one. But B3 makes a and b miai.



Failure

[Diagram]

Failure 1

The crawling in at B1 is too simple, since W2 can atari.

[Diagram]

Failure 2

The cut at B1 is too early. W2 is the only correct reply (see Beginner Exercise 205). After W6, the three Black stones including BC is caught in a connect-and-die.

[Diagram]

Failure 3

B1 is a failure.

[Diagram]

Failure 3

After W6, Black is caught in a double shortage of liberties.

[Diagram]

Failure 4

B1 here is also wrong.

[Diagram]

Failure 4

After W6, Black cannot set up a snapback since playing at a places Black in self-atari.

[Diagram]

Failure at Variation 2

B3 here allows W4 to block.

[Diagram]

Failure at Variation 3

This cut at Black 3 does not work.
