Kyu Exercise 93 / Attempts

Status of the corner group?  

fractic: I think Black is allready alive. The best attempt for White I can find is - aiming at shortage of liberties. Too bad that makes miai of a and b. Starting with is also no good.

unkx80: Almost there, but not quite...

another attempt  

fractic: I think I got it. A different way to set up a shortage of liberties. Now Black can't connect on a but he also has no second eye on the right side which at would give.

unkx80: Correct. =)
