Yes, he does. Black's only move is 1. ... d2+.
Because 1. ... b2+ loses to 2.Ra4+ Bxa4 (or mate in 1or 2) 3.Nc4+ Kb3 4.Nxb2 wins easily.
So: 1. ... d2
2.Kf1 e2+ 3.Kxe2 d1=Q+ 4.Kxd1 b2 (other moves, then white wins with Kc1 and Qb2 checkmate) 5.Ra4+ Bxa4+ (or white mates with Qxa2) 6.Kd2 and aft ...[text shortened]... + Kb3 8.Na5+ and back to c4, alternating between c4 and a5 or a3 depending on the kings choice.
