Beginner Exercise 29 / Solution

Solution

[Diagram]

Solution

The solution is to make a clamp at B1, threatening both a snapback at a as well as connecting underneath at b. Note that after B1, White at c or d would be self-atari.

[Diagram]

Solution

If W2 defends the snapback, then W3 captures, easy-peasy.

[Diagram]

Solution

W2 may also descend here or play at a or b, but B3 can make a snapback on the six White stones.

[Diagram]

Solution

Alternatively, W2 may be answered by making an atari at B3. As W6 captures two stones, both Black and White has two liberties each...

[Diagram]

Solution

B7 wins the capturing race by one move.


Failure

[Diagram]

Failure

The atari at B1 is wrong. When White plays the hane at W6, Black is stuck and is unable to make an approach move at a, which is a self-atari.

Note that although B1 is wrong, this failure diagram merits additional discussion. See Kyu Exercise 12 for more.

[Diagram]

Failure

The hane at B1 is also a mistake, because W2 can make an eye. After B3, W4 prevents an eye for Black. Just as the previous failure, Black loses by eye versus no eye.
