About this endgame

This is the same board as the opposition exercise, seen from the attacking side. answer a practical question: where does my king have to stand so that the pawn queens no matter what? For a pawn still on its own half of the board, and not a rook pawn, they are the three squares two ranks in front of it. If your king steps on one, you win even against perfect defence. That saves calculation: instead of counting pawn moves, you count how many moves your king needs to reach that rank. The usual mistake is pushing the pawn too soon. The pawn is not going anywhere, so the king goes first and clears the way, and the pawn follows. In this position you have seven king moves: four win and three let the win slip.
