I think your analogy is useful. However, I'd point out that the rook itself is not a fence post but rather a gap in the fence! An enemy king on b5 can move to a6. 🙂
You do not allow the king to get to b5 or b7 if you have a rook on a6. When he gets there you move the "Fence Post" to the other side as far away from the king as possible, h6.
The queen is a true fence post with additional powers.
Originally posted by ShinidokiK + R + R vs. K is much faster than K + R vs. K even if you do use extra pieces...
Here's my tutorial:-
Step 1) drop a rook.
Step 2) find the other guide on how to mate K+R v K
why bother teaching endgames with irelevant material? (eg. N+Q+K v K)
N+K v K+Q, on the other hand is much more useful.

Hope you find it useful. Always glad to help.

Freeing the Rh1 to move to the b file. Rh2 is just as effective

Still preventing Rh7

The King cannot be mated in the centre so go thereIn fact with K+R+R v K mate can be forced on any square on the board. It is easier and quicker to do it on the edge, and the Rooks can do this without the help of the King. However, to force it an a non-edge square all three pieces must be used. If you like to set up any starting position and state on which square you want the mate to occur, I will demonstrate this.

Here is a mate in the centre which would be somewhat more difficult to force.
Why don't you tell newbies how to get here from my starting position (pieces on original squares).
