Sunday Problem #76

Like Sunday Problem #75, this is a relatively simpler classic problem.

Black to play.

Solution
Solution (1)
Black’s group in this problem has no clean way of forming two eyes. This leaves her only with the hard-working atekomi of 1; if White responds passively with 2, then Black lives cleanly with 3–5.
Solution (2)
White, of course, will however fight back with the cut of 2. Here Black unleashes the corner kō tesuji of 3, and after 4–5 a two-step kō fight is created. This is the best result for both players.
