4. d7! c1=Q! 4... bxa1=Q 5. d8=N! cxd1=Q 6. Nf7#

5. Qb1!! 5. d8=N? Qc7! (5... Qf4? 6. Qb1 +- see the main line) 6. Qb1 Qxd8 7. Bxf3 Qc7! 8. Qh1 b1=Q 9. Qxb1 (9. Qh2 Qxe5 =) 9... a3 10. Kg2 Qc1! = 5... a3! 5... Qxb1 6. d8=N! Qf5 7. gxf5 b1=Q (7... g4+ 8. Kh4! (8. Kxg4? gxf5+ =) 8... g5+ 9. Kxg4 b1=Q 10. Nf7#) 8. Nf7+ Kh5 9. Bxf3+ g4+ 10. Bxg4#; 5... Qc4 6. Bc2! a3 7. Bxg6! +- 6. d8=N! Qf4 7. Qe4! Qf8 8. Qe1! 8. Qxf3? b1=Q 9. Qxf8 Qd3+ =; 8. Ne6? b1=Q 9. Qxb1 (9. Qe3 Qe7 =) 9... Qb4! 10. Qc1 Qxg4+ 11. Kxg4 stalemate 8... b1=Q 9. Qh1 Qxd1 10. Qh2! 10. Qxd1? Qf4 11. Qh1 (11. Nf7+ Qxf7 12. Qh1 Qf4 =) 11... Qh2+! 12. Qxh2 stalemate 10... Qf4

11. Nf7+! Qxf7 12. Kg3#

Thematic try: 1. Be4? b2! 1... Qxa1? 2. Bxf3 +- 2. Rb1 2. Rxc1 bxc1=Q 3. Bxf3 c2 4. d7 Qa3 5. Kg2 c1=Q 6. d8=Q (6. d8=N Qf8 =) 6... Qab2! (6... Qac3? 7. Qe4 Q3c2 8. Qf5! gxf5 9. Qd6+ g6 10. Qf8#) 7. Qe4 Qbb1! (7... a3? 8. Qxg6+! hxg6 9. Qh8#) 8. Qxb1 Qxb1 = 2... c2 3. Bxc2 Qxc2 4. Qxb2 a3! 4... Qxb2? 5. Rxb2 a3 6. d7 axb2 7. d8=N b1=Q 8. Nf7# 5. Rh1 Now it would be a mistake to play 5... Qc1? 6. Rh2! Qf4 7. d7! axb2 8. d8=N! b1=Q

The position is similar to one reached in the main line of the solution but now we have a rook on h2 instead of a queen.9. Nf7+! Qxf7 10. Kg3#

But black can save the game by 5... Qxf2! 6. Qxf2 stalemate
