Apologies if this is tagged wrong or in the wrong place.
I’ve been going over this puzzle for a little while now and I feel like I am missing something.
The puzzle set I am doing say that white is dead. How so?
I understand that if white plays inside at A12 or D13 then he is dead but what if white doesn’t?
If black fully surrounds then throws-in to capture then white captures and has a 4-long eye space which is live.
So how does black kill here?
