Yeah, Black could play almost whatever it wants. It's a draw anyway

Beatiful!

After 1... Rh1 this game is not a draw because it's white's turn: if it is black's turn it's a draw
(1... c4 2. h7 Kc2 3. Kg7 c3 4. g6 b1=Q 5. Rxb1 Kxb1 6. h8=Q Rxh8 7. Kxh8 c2 8. g7 c1=Q 9. g8=Q draw or also 1... b1=Q 2. Rxb1 Rxb1 3. h7 Rh1 4. Kg7 and so on).
White doesn't play 1. h7 because of 1... c4 2. Kg7 Kc2 3. g6 c3 4. Kf6 b1=Q 5. Rxb1 Kxb1 6. g7 c2 7. h8=Q (g8=Q c1=Q 8. Qb3+ [8. h8=Q?? Rxh8 9. Qxh8 white loses] Ka1... draw) Rxh8 8. gxh8=Q c1=Q draw.
So white does:
1. Kh7!! Rh4
(1... Rg1? 2. g6 Kc2 3. Rxb2+! Kxb2 4. g7 c4 5. g8=Q)
(1... b1=Q? 2. Rxb1 Rxb1 3. g6 Kb2 4. g7 c4 5. g8=Q)
(1... c4? 2. g6 Rg1 3. g7 Kc2 4. Kg8 b1=Q 5. Rxb1 Rxb1 6. h7 and so on)
2. Rxb2!!
(2. g6?? Rb4! [that's why black played 1... Rh4] 3. Rxb4 Kxb4 4. g7 b1=Q+ 5. Kh8 Qb2 6. Kh7 Qc2+ [you probably saw this kind of continuation] 7. Kh8 Qc3 8. Kh7 Qd3+ 9. Kh8 Qd4 10. Kh7 Qe4+ 11. Kh8 Qe5 12. Kh7 Qc7 13. Kh8 Qe5... draw)
2... Kxb2 3. g6 c4 4. g7 c3 5. g8=Q c2 [ends the solution, here is a possible continuation:] 6. Qb8+ Ka2 7. Qa7+ Kb2 8. Qb6+ Kc3 9. Qe3+ Kb2 10. Qe5+ Kb1 11. Qb5+ Ka2 12. Qg5!...
•12... Rc4 13. Qc1! Kb3 14. Kg6 Rc6+ and so on, white wins
•12... Kb2 Qxh4 13. Qxh4 c1=Q 14. Qb4+ Ka2 15. Qa4+ Kb2 16. Qb5+ Ka3 17. Qa5+ Kb3 18. Qd5+ Ka3 19. Kg6... and so on, the solution is very long but white wins
•12... Rh2? (or similar moves) 13. Kg6 Kb2 14. Qf6+ Ka2 15. Qe6+ Kb2 16. Qb6+ Ka3 17. Qc7! -- (rook move) 18. h7... white wins!

I hope that this answers everything (and that I've written correctly all the moves). If it doesn't just comment.

I still think its a draw

I edit on your comment, just to argue that the moves you purposed (as in fact Rh4) keeps the game a draw

"So white does:
1. Kh7!! Rh4
(1... Rg1? 2. g6 Kc2 [this is a mistake; Rg4 keeps it a draw] 3. Rxb2+! Kxb2 4. g7 c4 5. g8=Q)
(1... b1=Q? 2. Rxb1 Rxb1 3. g6 Kb2 [this is a mistake; c4 keeps it a draw]4. g7 c4 5. g8=Q)
(1... c4? 2. g6 Rg1 3. g7 Kc2 4. Kg8 b1=Q 5. Rxb1 Rxb1 [this is the wrong move; Rxg7 keeps it a draw] 6. h7 and so on)"

Hope it helps

Héctor.

I concur with the others

This is a draw. What happens if black plays 6... Rxh5? After 7. Kxh5 c2, you can't separate the king from the pawn, so you either have to let it promote and you have the theoretically drawn queen and king vs. queen and king ending or you have to keep on giving checks, leading to a draw by repetition.

It pisses me off that I'm losing points on tactical puzzles that nobody has bothered to check for accuracy.
