Knight vs Rook Pawn
White to play and draw
PlayYour knight must stop a rook pawn on the sixth with its king escorting it, and your own king is a continent away. The corner that usually kills knights is, for one rank more, still survivable.

The theory
A knight is the worst piece against a rook pawn. The corner it must defend gives it no room behind the promotion square, and half its usual circuits simply fall off the board. Yet the ending has a sharp, learnable boundary, and the difference is one rank of the pawn.
Pawn on the sixth: draw. Against a pawn on h3 the knight owns a small circuit of guard squares around h1 and g1: attacked by the king on one, it hops to another that still covers the coronation. The escort king can shoulder and probe forever, but the circuit closes on itself and the pawn never gets to advance safely.
Pawn on the seventh: usually lost. On h2 the corner geometry flips. The knight's guard squares shrink to a set the king can visit one by one, and zugzwang does the rest: sooner or later the knight must leave the last square that stops promotion. This is the famous corner weakness, and it is unique to knights; a bishop of the right color never runs out of waiting moves.
The practical rule to carry home: racing to stop a rook pawn with a knight, arrive BEFORE the pawn reaches its seventh, and think in circuits rather than squares. In this drill only two first moves hold, which is exactly how thin the circuit is.
