Answers.Text: You should also give the variation when black sacrifices the rook with the white king furthest away from the `h`-pawn. (`5... Rxa7`)

Answers.Text: I was thinking about something else for Black, more along the lines of `1...Ra5!?` so he can actually try and hold the game... Still, I have upvoted because of your thorough coverage.

  White has a very simple strategy to win this position - 
  
  Prevent the g-pawn from being captured for free by the Black king (the Black rook cannot capture it because it is tied to the defense of the a-pawn promoting on a8. White wins if White can win the h-pawn)
  Move the White king over to support the promotion of the a-pawn. 
  At the right moment, occupy the b-file with the White rook and support the g-pawn from b3. Then White's king can have a safe square on the b-file to promote the a-pawn.
