New Concept: Knight's Square (N+RP Endgame)

I just came up with what I THINK is an original concept in the endgame. 

In a King and Knight and Rook Pawn endgame, there is 1 vital square the knight has to get to when the pawn is at the 6th or 7th rank. 

A most excellent lesson!

Isn't it kinda self-evident? To promote the pawn you need to protect the promotion square. Whether it's a rook pawn or some other pawn is irrelevant. Neither is the rank of the pawn, for that matter (the pawn promotes as long as the king can't get into the corner square).

Might as well introduce a "bishop's diagonal".

It is kind of self-evident. There are also endgame studies using this kind of manoeuvre to mate the opponent - or chase the king out of the corner when the pawn is on a6/h6/a3/h3. It is not relevant for winning the endgame unlike the following diagram where the relationship between the black king and the white knight matters for the outcome!

yeah it is ig. I think it still might be a good concept for beginners to learn, if they just keep moving the knight around they won't be getting anywhere

That was me. Just being able to force the king in the corner with only my king, knight and pawn left was hard to do. Since I did not know how I could force his king to stay in the corner it ended up a stalemate.
