Kyu Exercise 4 Solution
Difficulty: Advanced
Keywords: Life & Death, Problem
Solution 1
The simpler solution would be a placement on the second line. Black 3 forces White 4, and Black 5 reduces the eye at the bottom to one in sente.
Why sente? Because if White obstinately makes the other eye with 6, Black captures White in a connect and die with 7. or easier to see, the three stones above --Dieter Solution 2
The placement at the first line also works, but Black 3 and 5 are probably a blind spot.
If White 2 simply captures the two Black stones, Black can simply set up a snapback with 3 and 5.
Black 3 is incorrect. Although Black 5 is a ploy to reduce the eye in sente, but White 6 answers correctly and lives.
Black 9 and White 10 are miai. Other variations
The atari at 1 is a mistake.
Black makes a throw-in at 5, but White occupies the vital point of the bulky five with 6 and lives. See also: This is a copy of the living page "Kyu Exercise 4 Solution" at Sensei's Library. ![]() |
