Beginner Exercise 73 / Solution

Sub-page of BeginnerExercise73
A solution?  

Blake: After the marked stone has been played, I don't see how White can kill the group. It guarantees an eye at a.

Proofs I  

After a or b, White is either in atari or close to it.

Proofs II  

After B2, the eyes are obvious at a and b.

unkx80: B2 can be played at c too.

Proofs III  

(Best for White.)


Dansc: Enlarging the eyespace with B1 fails. Black's eyespace is a bulky five, so W2 kills the black group - a and b are miai for kill now. The bulky five shape is the same reason a black stone at W2 would make the group alive.
