Help needed with King/Rook end game

This is the second time I’m trying post, but apparently I suck at it. So, I need help figuring out this problem. Im working on how, in this position, every time the kings meet, I win opposition. Been working on it a bit and can’t seem to figure it out, opposition is a new concept to me . Any help and and a wee bit of explanation would be super helpful !! Thanks in advance

Here is a puzzle to test the strategy:

The above is an example of how to force you opponent to take opposition in order to gain an advantage. Here is a winning play of opposition in a king-rook to king-rook-pawn endgame:
