The hane of Black 1 is the vital point. White 2 is the move to use to try hardest for viable shape, but at that point Black’s pushing in once more is a good move. White 4 is then the only move to play in response, but Black 5 is the coup de grace. White is dead.

Correct Solution Variation

Should White answer Black 1 with 2, Black 3 is the move at the vital point that ends all counter play right there.
