Almost corner squares

I recently heard briefly there was a name for the b2, g2, b7 and g7 squares for the endgame. From what I remember when in the endgame if you have a pawn on one of these squares it is easier to defend your King by having the King next to it and a Rook defending the other side that your King is not covering or something to this effect. Does anyone know what this concept is?

I just can't remember what it was. I believe it's from an article that was written on chess.com

I haven't come acoss a specific name for those squares. Of course, in endings with a pawn, which file the pawn is on is often important. In many endings a rook pawn is special. And in Q vs. P, the rook pawn and bishop pawn are special.

When is the knight pawn special? An obvious case is with a white pawn on b5, white king on b6, and black king on b8, when White has only one move to win. On the rook file it would be a draw, and on a center or bishop file White would have two moves to win. In R vs. R with a passed pawn, both a rook pawn and a knight pawn are treated as special cases.

That still doesn't give you a name for your almost corner squares. Sorry I couldn't help with that.

Fianchetto squares.  These squares are often occupied by bishops in the opening (e.g. 1.c4 2.g3 3.Bg2) using said maneuver so chess speakers will know which squares you are talking about.

No, like I said this is only for defense not trying to promote a pawn or in the middlegame with the Fianchetto. I failed to mention this is also when the both sides still has pieces in the endgame with either a Queen or Two Rooks.

The name will help whoever you are talking to visualize where those squares are.  Doesn't matter what phase of the game you are talking about, the fianchetto (or almost corner) squares are in the same place, yes?

It matters in terms of the defensive concept. If you don't know what the concept is then the placement of the square does not matter.
