Black plays first.
Black cannot play elsewhere.
If Black plays first, then ensures life and White cannot defend all of a, b and c simultaneously, so White dies.
If connects, then connects as well. Since White have too many liberties, Black cannot win the capturing race and have to fight the ko for life. Thus the status of the White group will hinge on the outcome of this ko as well. However, this is a failure for Black.
The White group is dead.
