There are 5 squares to mate on and this was with best play by Black to move and White does quicker going to Ke7 on move 7. Black can also play to 6... Ke8 and then White plays 7. Kc7. Also, White has 1. Kc5 here so while a great endgame study to post, this would be an ambiguous puzzle. Great post though.

I've lost count of the number of times I've seen this done the wrong way !

The position is Drawn - the Black king has only to go to opposition on the same file, or if the pawn is advanced, move back to block it ...

As a general rule, Black tries to occupy one of the two squares in front of the pawn but when that isn't possible, moves to a position on the same file as White's king so as to be in opposition to it.

Much more to this than first meets the eye !  Why Black promotes to a rook instead of a queen isn't immediately obvious until you see the fork: Rf5+
Capture by a queen would result in stalemate (the White king is left with no legal moves) but by a rook will eventually win !

O/k, White should play 6.Kh8 to be as obstructive as possible but it's still a fun & instructive puzzle.

Vengence69 and stephen_33,
The diagram you've shown can be easily summed up:

If it's White to move, then Black has a forced draw. (So does White.)

If it's Black to move,  then White has a forced win.

6. Kh8 Kg6 7. Kg8 R moves (except Rf8?? DRAW) 8. Kh8 Rf8#

The position is an endgame study by Scossi from either the 18th or 19th Century I think. Here is the full study:
