how do you prevent them from dillydallying back and forth though
Each row force back is like a mini opposition checkmate.
He is on d5, your rook moves to h4, staying on row 4 until you can push him back.
Manuver your king in front of him. If he is on d5, you want d3 (although you want to be on d3 while it is your turn).
Of course he is a moving target and will make one move per turn. If he backs up to row 6, no problem.
Really, if he is on d5, you probably need to be on c3 on your turn. He will move to either c5, or e5. If he moves to c5, you move Rh5 and push him back one more row. If he moves to e5, you go to d3. He will either keep moving toward your rook, or at some point turn around. When you are on d3 if he moves back to d5, then Rh5 forces him to row 6. If he keeps going toward your rook, you keep chasing with your king.
The problem many beginners get into is when the king gets so close to the rook that the rook is attacked by the king. In that case you just cross all the way to a4 (Ra4). The king cannot follow without opposing your king. You either keep chasing his king after that (if he keeps moving away from your king), or you reach an appropriate opposition.
One more pitfall.
You want the opposition to occur at the end of your opponents move.
If you are on f3 when he is on g5 (rook on a4), when it is your move DO NOT play Kg3. He can then play Kf5 and move all the way toward your rook again. Instead, waste a move with your rook (e.g. Ra4-b4), now he has to move likely giving you the opposition. If he plays Kh5 then you play Kg3 and he will definitely give you the opposition then.
Never move your king into opposition, always manuver so that he has to move his king into opposition, wasting a rook move if necessary to make him move.
I am sure the long game sequence entered before illustrates all this, although I didn't actually step through it.
The process is really simple, in spite of the fact that it needs many words to describe. Step through the move sequence that was posted after reading this and a light will come on.
