Solution.

After the solution, how does the middle group make two eyes?

Save the middle group.

Black ends in gote, so white begins by attacking, and I think this is Black's best response. After W6, Black must make an eye with B7 at a, and b & c are maiai for the second eye. This is ko for life, though, since, if black fills the ko first, white can play a, reducing the group to one eye.

Is that the best black can do?

Save the middle group.

fractic: With B7 black lives unconditonally with eyes at the circled points.
