The theory
Knight and pawn against a bare king is winning, but the pawn still has to survive until the king arrives. The knight's placement decides how easy that is.
Defend from the rear. A knight behind its own passed pawn is immune. Capturing it takes the enemy king a move away from the pawn's path, and after the pawn advances the king is outside its square. Here 2.Nd2 guards b3 from behind, and 2...Kxd2 3.b4 simply queens.
Rear for your pawn, front for theirs. These are two different jobs and they need opposite squares. To stop an enemy passed pawn you get in front of it and blockade. To defend your own passed pawn you sit behind it, where the defense costs nothing and cannot be taken.
In this drill the black king will camp in front of the pawn. Hold it from behind, walk your king across, and promote.
