No, since in a) the black queen doesn’t deliver the check, the black king does.

In fact, in (a) it is double-check (and the Q guards c7).
Interesting and subtle difference between this finale and the similar s# finale with Isardam only (see Turnbull & Emmerson, The Problemist i/97), or, as in this position which cuts the pawns and some of the moves from above:
White Kc5 Qg4
Black Ke6 Qf7
HS#2.5 (a) Isardam (b) Isardam + AntiCirce
(a) 1…Ke5 2.Qd4+ Qf6 3.Kd5+ Qd6#
(b) 1…Qd7 2.Qf4 Qe8 3.Kd6+ Qb8#

No Joost and Stephen: in (a) the bK is not checking the wK – for the same reason the wK is not checking the bK.

Indeed – you’re right! The bK needs to be reborn too. The bK is still necessary to thwart White’s attempts to parry by observing d8 (e.g. Qh5 or Qd2). Apologies to Julia who was right all along!
