Michael (14 kyu): I think, White would play this way to live.
HolIgor: Hint. Black 5 was wrong here.
Jasonred : I was reading the manga and came to the same conclusion as Michael? Where else... wait... dammit. I thought a play at a was suicide, but then I realised it ISN'T...
Hyppy Michael's solution, simplified. As you can see, it does not quite work.
GodRaisty Another even better solution for black is
Symplicity: That doesn't work either. White plays at a to capture and gets 2 eyes, rather than connecting at b.
ZimoLi: No, that won't work. If white plays at a, then black b captures those three stones and kills the white group.
