Black can choose the next move between A and B.

Later, there are the right of black, A or B.

And later, there is a gote end game zone.

White 2 is very important.

The sequence up to 3 is not good.

Because this result is same to the next dia.

Black 1 is a gote end game but, white 2 makes black 1 sente end game.

White 2 is also important.

If white 1,  black can capture the corner, and whites are seperated each other.
