Main line
There is absolutely no time to expand the eyespace. White has to play at the vital point right now. And the vital point of this shape is 1.
The points 2 and 3 are miai and after the 2-3 exchange, a and b are miai.
The reason that 1 is the vital point lies in the fact that White can answer the atari of Black 2 with White 3. Without 1 in place, Black would capture three stones. Failure
As said before, expanding the eyespace is not right. Black plays atari at 2 and after White 5, Black can start a ko with 6 at 2. Life in ko is not sufficient.
This shape does not call for the 1-2 point. The points a and b are miai to keep White down to one eye, and Black destroys the other eye by playing 2. Playing 2 at b also works. Black should not play the atari as in the previous diagram, because that permits ko. In fact, White 1 destroys more eyeshape than it makes and she dies unconditionally.
