The 1-2 point prevails the 2-2 point again.
There is no way White can attack. The distance between 1 and the marked stone is wide enough for him to make a second eye (the circled point).
If Black carelessly plays at the 2-2 point, White takes the VitalPoint with 2 and sets up an ApproachKo. Black can't block at A because of damezumari. So he has to fight the ko at 2. After White recaptures the ko ...
... she connects at 1, making the 4 Black stones atari. Black takes the ko with 2 making 3 White stones atari; White connects at 3, and Black makes an eye with 4. Now White takes the ko.
So, White has to play an extra move, and if Black loses the corner, he will have played twice elsewhere in return. Anyway, living unconditionally is much better for Black.
Enlarging the eyespace with 1 is dubious. After White 2, Black has to defend his cutting point with 3. Further enlarging the eyespace with 5 forces 6 and now White can either atari at A in the future, or if Black plays there, make a FarmersHat nakade at B.
Fancy play at 3 doesn't help much. After White 4 on the 2-1 point, White can answer Black 5 with White 6, preventing any flight. Black has only one eye. 7 and 8 are miai.
Black does better to try to run with B 3, eliciting W 4. Now B 5 sets up a ko.
B 1 leads to a throw-in ko.
