Mate in 2.
Here, white has a mate ready for every possible black move:
1...Kc5 2.Bxe3#; 1...Ke5 2.d4#; 1...B~ 2.Bf6#. Unfortunately, white does not have a neutral "waiting move": every possible key move spoils at least one of the variations. So after the key move some black moves must be provided new mates. Or not so new...
