Kyu Exercise 16 / Solution

Sub-page of KyuExercise16

Ex 1

Ex 1: Black to play  

SnotNose: Ko.

Ex 1: Black to play  

SnotNose: Alive.

Ex 2

Ex 2: Black to play  

SnotNose: Alive. B3 needed to avoid a ko. If W2 at B3, Black can squeeze for life.

Why not B1 at B3? If the shape is alive even with fewer outside liberties, shouldn't the potential of B playing at W2 be kept for later (ie making W2 gote)?


unkx80: Suppose the White wall is changed as shown. Playing at a gives 5 points, while playing at b gives 4 points. Maybe that's the intention of the problem author?

Ex 3

Ex 3: Black to play  

SnotNose: Alive, a and b are miai. No ko when this shape is not in the corner.

Ex 4

Ex 4: Black to play  

SnotNose: Alive. Same as previous problem.
