How do you win this

This is how I would solve it.
Promote to a rook. You are already winning
Why not queen?

This is how I would solve it.
this draws for black as they get opposition, they just stay in front of the pawn and if whote moves the king, take opposition, repeat, until the king is on the last rank, stalemated or winning white’s pawn. Kd2 or Kf2 getting the king in front of the pawn is winning

Show me a game using my exact moves where this happens. I want to see what you mean.
Well white has to get ahead of the pawn first
