Sunday Problem #57

This is a classic tsumego that sharp-eyed readers may remember from Hikaru no Go.

Black to play.

Black 1 is the correct starting move; most other killing attempts fail to White playing at 1. Following, after white 2, 3–5 strictly reduce White to one eye.
If white tries 5 instead of 2, then black 4 kills.
