The theory
The old proverb says knight endings are pawn endings, and this position is the proof. In a pure pawn ending, one defender covering the queening square loses to two attackers. Replace the fighters with knights and the arithmetic survives: a knight defending the promotion square alone, king absent, gets outnumbered by knight plus king.
The blockade that is not a blockade. A knight CONTROLLING the queening square from a distance looks stable, but unlike a king it cannot hold ground while defending itself. Attack its perch and it must hop to another square that still guards the target; the set of such squares is small and shrinks near the edge. King and knight together visit those squares faster than the defender can rotate through them.
The defender's real weapon is the sacrifice: knight for pawn is a dead draw, and a perfect defender offers that trade in every line. The attacker's discipline is to keep the pawn defended at the moment of every knight exchange threat, which is why the king stays glued to the pawn while the knight does the chasing.
When it would be drawn: defending KING in front of the pawn, or a rook pawn whose corner cramps the attacking knight too. Centralize this pattern and you will know instantly, in any knight ending, whether the extra pawn is a result or just a feature.
