White wins

1. d7 a2 2. d8=Q a1=Q 3. Qd6! Qc1+ 4. Kh7! 4. Kg7? Qg5+ 5. Kf7 Qh5+ = 4... Qg5 4... Qh1+ 5. Kg7 Qxg2 6. Qf6+ Ke4 7. Qc6+ +- 5. Qd7+! Kf6 6. Qd8+! Kf5 7. Nh4+ Kf4 8. Ng6+ Kf5 9. Qd7+ Ke4 10. Qd3#

Both the d-pawn and the promoted white queen makes the same moves (d6-d7-d8). It almost looks like the d-pawn has promoted twice on d8!
