...because one of the netting stones gets laddered first.
Therefore white dies, right? It looks like he does. ( A9 and A7 are miai )
However, if D8 is good for me, then according to the proverb, it should be good for him.
I was idly looking at it, assuming that I would kill easily if I got the vital point at B8.

The failed ladder has two side effects. It gets white his second eye, but it shorts white on crucial liberties and endangers his first eye. So black attempts to rescue his vital point stone, white blocks, and black completes the tesuji:
