Am I right? No, it's a win for white. The fun here is black's repeated zugzwang, and white controlling the diagonal a6-f1 at which black must promote. The two combined give white the opportunity to push the pawn forward to its dead and later on separate the black bishop from the pawn, dooming them both. 1.Nc6+ Ka8™ 2.Bc8 f4‡ 3.Ba6 f3‡ 4.Kf2 g1Q+‡ 5.Kxg1 Bg2 [ 5...f2+ 6.Kxh1 f1Q+‡ 7.Bxf1+-] 6.Kh2 Bf1 [ 6...Bh3 7.Kxh3 f2 8.Kg3 f1Q 9.Bxf1+-] 7.Bxf1 Kb7 8.Ne5 f2 9.Kg2 Kb6 10.Kxf2+- I think the "only move" and "zugzwang" signs don't come out right.
