Chess Puzzle #nrJxl — Advanced, Black to move, endgame

Position

White: king c2; rook h5; pawn g4. Black: king b4; knight e4; pawns b5/c3/d4. Material is balanced. Black to move.

Solution (2 moves)

1. Opponent setup: g5 — pawn g4→g5. Now Black to move.
2. Best move: Kc4 — king b4→c4. Opponent replies Rh4 (rook h5→h4).
3. Best move: Nxg5 — knight e4→g5, captures pawn.

Why this works

Black's king on c4 activates toward the center while the knight on e4 is perfectly placed to strike g5. After 1...Kc4, White's rook on h4 is too far away to defend the advanced pawn or create counterplay. The knight then captures 2...Nxg5, eliminating White's only pawn and leaving Black with a knight and three pawns against a lone rook—a completely winning endgame. The rook cannot generate perpetual checks or fortress because Black's pawns (especially the passed c3 and d4 pawns) advance faster than White can create threats. White's king on c2 is trapped near the advancing pawns and cannot stop them in time.

What to practice

In rook-versus-knight endgames where the defender's pawns are advanced and dangerous, prioritize eliminating the defender's only pawn first. The rook alone cannot hold back multiple passed pawns without pawn support. Recognize when an active king position (c4 instead of b4) opens tactical space for your pieces—here it allows the knight a forcing capture while the king guards against rook checks along the 4th rank.

Tactical themes

crushing, endgame, short. The key move is Kc4.
