Gokyo Shumyo, Section 1, Problem 16 / Solution

[Diagram]
Black lives  
[Diagram]
Main line  

Throwing in at 5 is key to life. (This is an example of oshitsubushi.)

[Diagram]
Variation  

If White continues to destroy Black's eyeshape, she runs out of breath after Black 7. Black will have to connect at a later, but still his eyespace is almost filled with a straight four shape, giving life.

[Diagram]
Mistake at 5  

White 6 makes miai of a and b to destroy the second eye.


[Diagram]
Wrong  

After 4, a and b are miai for killing the corner.

[Diagram]
Wrong (variation)  

Black will eventually have to connect at a and b, leaving his eye almost filled with three stones, so he dies.


[Diagram]
Wrong (ii)  

White 4 makes miai of 5 and 6. White 6 makes miai of a and b.


[Diagram]
Wrong (ii)  

Black 1 here obviously makes only ko, and ko is not good enough.
