Kyu Exercise 10 / Solution

Sub-page of KyuExercise10



Black 1 kills by nakade. There's no way White can make two eyes now.

Var 1: Eye in the stomach  

If W2, B3 makes an eye in the stomach. If White does play inside the group, Black can fill all outside liberties and eventually atari at either a or c. If White next plays a or c, Black b makes a rabbitty six inside White's eyespace.

Var 2: Bulky five  

If W2 here, B3 threatens to connect to the vital stone, next B5 almost fills with a bulky five.


Failure at 3  

Black 3 here is a mistake. W4 turns the position into seki.

Failure at 1  

B1 here is also wrong. W2 forces B3 and then W4 occupies the vital point. Next, Black a doesn't create a killing shape.

Failure (ii) at 1  
Failure (iii) at 1  

In both cases, White is able to take the vital point.
