White plays her second kikashi in the lower left corner.

:
Black gives atari at White's three stones at the top, intending to save his large group at the right.

He might consider saving his group at the left, e.g. by playing the atari at White's two stones in the lower left (that White will not answer), but then Black's larger group at the right will die by White's continuation at .

White uses her sente in the lower right corner to erase Black's potential second eye in the left centre.

White will win the game by a large margin.
