Chess Puzzle #SWj3a — Advanced, White to move, endgame

Rating 1804 · Advanced · endgame, equality, pin, short.

Position

White: king d5; rook a7; pawns c4/e5. Black: king e7; rook f2; knight d7; pawns a4/b6. Black is ahead by 3 points of material. White to move.

Solution (2 moves)

  1. Opponent setup: Rf5 — rook f2→f5. Now White to move.
  2. Best move: Kc6 — king d5→c6. Opponent replies Ke6 (king e7→e6).
  3. Best move: Rxd7 — rook a7→d7, captures knight.

Why this works

After Black's 53...Rf5, White's king on d5 is pinned along the fifth rank—if it moves away, Black's rook captures the pawn on e5. The solution 1.Kc6 breaks this pin by moving the king perpendicular to the rank, escaping the rook's control. The follow-up is critical: Black's 1...Ke6 (forced, as any king move away from e6 allows 2.Rxd7, winning the knight outright) is met by 2.Rxd7, which wins the knight because it is no longer defended. The knight on d7 was Black's only piece preventing immediate collapse; with it removed and only a rook versus rook endgame remaining, White has consolidated the position from a losing one into a drawable, material-equal endgame.

What to practice

Recognize when a pin is directional and can be escaped by moving perpendicular to the attacking line. The king on d5 pinned along the fifth rank is freed by Kc6 (moving along the sixth rank), not by defending the pawn. This pattern teaches you that a passive response ('I'll defend the pinned piece') often loses; instead, ask whether the pin can be broken by a tempo-gaining move that forces the opponent into an unfavorable continuation.
