Gokyo Shumyo, Section 1, Problem 30 / Solution

Black lives  
Main line  

Wrong 1  

The hane makes miai of a and b.

Wrong 2  

Well, wrong, I can't figure out how White will kill Black ... Someone ?

Wrong 3  

This is my best effort: a gote seki for White.

Zook's Answer  

Zook: To the previous poster. Please sign your contributions in a L&D discussion. You can use a nickname.

W4 leaves a and b as miai. If B3 at c, W4 at d.

Refutation to Zook?  

lightvector: I don't see how Zook's answer works. Now if white finishes the process of squeezing black's space to 1 eye, black will get another at a.

Wrong 4  

Becomes ko.

Black lives?  

fringD: How does white kill this? below is the best i can do

looks like it.  

fringD: can't seem to beat it. i tried some other moves too.

Zook: have you tried White 3 at a ?

Black lives?  

unkx80: Black dies.


fringD: yes i see it now... if i play elsewhere, white takes the vital point... turning a and b into miai

Wrong 2  

I think Black is alive, isn't it ? It seems there are 2 solutions to this problem.
