Maybe with this being the puzzle, the king hasn't moved and h8=R, so move 2. 0-0-0

here is the answer: 1. h8=Q, 2. Qg8, 3. Qe8, 4. Qe5+ 5. Qh8 6. Qa1+ 7. Qxa1+ 8. Qa7#. or something like that. this is a chess mentor course.

Balto, moving the king is a blunder. After that King C7,B7,orD7 mates black. 1.h8Q forces black to play a8Q! in hopes to create a stalemate.

Ah, it's a real puzzle. 5. Qh8 will win. Thanks

Can you explain why 2.Qg8 is neccessary and why you can't simply do 2.Qe8 ?

Congratulations for telling us things we already know, while showing us that you haven't read the other comments or are intentionally wasting space in your topic.

 Okay, ignoring that Kortam placed coordinates on his diagram, if the King hadn't moved, wouldn't the white pawns be moving downward?

 Sunshiny did so in post #6. If 2.Qe8, 2...Qg7 draws. 2.Qg8 is the only move that wins for white.

This is what Benws was trying for:

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

Move 4 and onward seem pretty straightforward to me. The first three moves are pretty interesting, though. First, you need to catch that ...Qg7 draws, so you need to deny this square. Then, you need to realize that Qf8 fails, as ...Qd6+ will also draw. Therefore, you have to step, first to g8, and then to e8. Allowing ...Qd7+ is obviously safe because of Kxd7#, and allowing ...Qd5+ is also safe, as white has Ke7+.

 Being a puzzle, it takes a few liberties. The king, having been placed on the board, hasn't moved. The pawn becomes a rook and castling can take place because neither king nor rook moved. I don't believe the rules say that the king must be on their respective starting squares in order to castle. It is taken as a given, but again, being a puzzle,...
