White to play. Where's the vital point to make the black group alive?

Herman Hiddema: After 1, black can tenuki, because the best white can get is seki. In fact, black can even ignore any follow-up move by white here, because if white plays the vital point a, then b and c are miai and black does not need to respond because he will always get one of them.
