Gokyo Shumyo, Section 1, Problem 39 / Solution

[Diagram]
White lives  

White makes two eyes with one strike. There is an eye at each circled point.

[Diagram]
Main line  

The main line just shows the completion of the first eye.

[Diagram]
Continuation 1  

Now B1 and W2 are miai for the protection of the second eye.

[Diagram]
Continuation 2  

If the circled liberties at a and b were filled, Black could kill this way.


Once the vital point has been played (W1 in the solution diagram) there is not much room for mistakes by White, so we will concentrate on what can go wrong at the first move.

[Diagram]
Failure 1a  

W1 is a natural move. But up to B4, a and b are left as miai for the kill.

[Diagram]
Failure 1b  

Here W3 and B4 are miai: up to B6 is one way for White to die.

[Diagram]
Failure 2  

The 1-2 point is another natural point to try, to make life, but Black can occupy B2, which is connected to the marked stone through a large monkey jump.
