Rook vs Knight Endgame: How the Knight Holds the Draw

Rook against a lone knight is a draw in almost every position, but it is not an automatic one. The defender has exactly two ways to throw it away: letting the knight stray from its king, and getting both pieces trapped in a corner, where even a knight sitting right beside its king falls to zugzwang.

The knight lives next to the king. A knight defended by its own king cannot be won by the rook: any attack is simply met by a short knight hop that the king still covers. The moment the knight strays into open space alone, the rook builds a fence around it and wins it before the king can arrive.

Avoid the corner. The second trap is having both pieces jammed into a corner. There their mobility collapses, even the knight on a square like g2 is awkward, and the rook can force the knight to move away from the king and then round it up. Keep steering toward the center, where the knight always has a safe square beside the king.

In this drill the rook will hunt the knight and try to drive your king to the edge. Keep the pair together, head for the center, and there is no way through.
