[Diagram]
Correct

White can live with either a or b, but plays kikashi with W1 before living.


[Diagram]
No kikashi

If White immediately takes a vital point, she lives too, but now she has failed to force Black. If White plays W3 later in the game, the value of that move is reduced to 4+ points, and Black can choose to ignore it. If White eventually captures the BC stones with W5 and W7, Black can make shape with B6 and B8. Also, W1 has now been turned into a superfluous move, a one-point loss.



[Diagram]
Difference

The difference with the correct diagram is that, if Black ignores W1, then the capture of the BC stones yields not merely 4 points, but also life for the corner. Now look again at the previous diagram, which is as if White plays at a here, in exchange for a black move elsewhere, really a ridiculous turn of events.

Comment

Comment: Depending on the situation, if White plays at W1 alone, then later the peep at W3 may turn out useful.
