Rook vs Knight
Rook versus a lone knight, with no pawns on the board, is a draw when the defending side plays accurately — an extra exchange of material still isn't enough to force a win against a well-placed king and knight.

A rook outranks a knight in material value, but a lone knight with its king nearby can defend this ending indefinitely. The rook alone can't create the kind of mating net needed to trap the king, and the knight is flexible enough to keep hopping to safety whenever the rook tries to close in.
The defensive plan: stay central, stay connected
The defending side's job is to keep the king and knight close together and avoid drifting toward a corner, where the pair becomes far easier to trap and fork. Centralizing moves like Kd2 and knight hops such as Nd5 in this position typify the calm, patient defense that holds — there's no need for anything fancy, just avoiding forced sequences that separate king from knight.
Where the defender can lose
This draw isn't automatic — if the knight gets stranded on the rim of the board ("a knight on the rim is dim") or separated from its king, the rook can often win it outright, which then converts to an easy rook-vs-king win. The single biggest defensive rule is: never let the knight get more than a move or two away from its own king.
Frequently asked questions
Is rook vs knight always a draw?
With no pawns and careful defense, yes. The knight and king simply need to stay coordinated and central; a rook alone can't force a win against that setup.
How does the knight side hold the draw?
By keeping the king and knight close together at all times and avoiding the edge of the board, where the knight has fewer safe squares and becomes easy to trap or fork.
Can the rook ever win this endgame?
Yes, if the defending side lets the knight drift to the rim of the board or get separated from its king — in that case the rook can often win the knight and the resulting king-vs-king ending is trivial.
Why is a knight harder to trap near the center?
A centralized knight has more squares to jump to, making it much harder for a lone rook to corner without support from its own king.
