Ko

Confused: It looks to me, that White needs to give atari to the marked black stone, otherwise Black will take one of the two remaining liberties of the white group at the top or take the single white stone.

If white gives atari with W1, the best I came up with is to set up a ko in the corner with W3. White needs to win this ko twice in order to kill the black group.

Is there a better solution?
