1st Commendation

This problem has multiple solutions. A simple move count shows that Black must make at least 19 moves. The extra 1 move can either be by the Rh8, or by the Q. In each case there are still many alternatives. For example, with the extra move by the R:

1. a4 d5 2. a5 Bf5 3. a6 e6 4. axb7 a5 5. h4 a4 6. h5 Ra5 7. h6 Na6 8. hxg7 h5 9. b8=N Nh6 10. g8=N Bc5 11. Ne7 Ba7 12. Nc8 O-O 13. Ne7+ Kh8 14. b3 Rg8 15. Ba3 Rg4 16. Bd6 c6 17. b4 Rxb4 18. Bg3 Qb6 19. Ng8 Qb5 20. Bh2 Nc7

An example with the extra move by the Q:

1. a4 d5 2. a5 Bf5 3. a6 e6 4. axb7 a5 5. h4 a4 6. h5 Ra5 7. h6 Na6 8. hxg7 h5 9. b8=N Nh6 10. g8=N Bc5 11. Ne7 Ba7 12. Nec6 O-O 13. Nd7 Qa8 14. Nf6+ Kh8 15. b4 Rb8 16. Bb2 Rxb4 17. Be5 Qb7 18. Bh2 Qb5 19. Nb8 c6 20. Ng8 Nc7

Finally, an example with the extra Queen move and a clever Knight swap:

1. a4 d5 2. a5 Bf5 3. a6 e6 4. axb7 a5 5. h4 a4 6. h5 Ra5 7. h6 Na6 8. hxg7 h5 9. b8=N Nh6 10. g8=N Bc5 11. Ne7 Ba7 12. Nec6 O-O 13. Nd7 Qa8 14. Nf6+ Kh8 15. b4 Rb8 16. Bb2 Rxb4 17. Be5 Qb7 18. Bh2 Qb5 19. Nb8 c6 20. Ng8 Nc7
