Chess Puzzle #1r3hd — Expert, White to move, endgame

Position

White: king e2; rook d7; bishop f6; pawns c4/c6/g3. Black: king e8; queen b6; pawns a7/b4/f2/f7. Black is ahead by 2 points of material. White to move.

Solution (4 moves)

1. Opponent setup: b3 — pawn b4→b3. Now White to move.
2. Best move: Re7+ — rook d7→e7, gives check. Opponent replies Kf8 (king e8→f8).
3. Best move: Rb7 — rook e7→b7. Opponent replies Qxc6 (queen b6→c6, captures pawn).
4. Best move: Rb8+ — rook b7→b8, gives check. Opponent replies Qe8+ (queen c6→e8, gives check).
5. Best move: Rxe8+ — rook b8→e8, captures queen, gives check.

Why this works

White's combination exploits Black's vulnerable king position and the advanced f2 pawn's distraction value. After 1.Re7+, the king is driven to f8 (forced). Then 2.Rb7 attacks the queen, and any queen move allows 3.Rb8+ with a devastating check on the eighth rank. When Black tries 2...Qxc6 (capturing the pawn), 3.Rb8+ forces 3...Qe8 (the only square defending the back rank), and 4.Rxe8+ wins the queen with check. The king has no escape squares—f7 is blocked by its own pawn, and e8 is now occupied by the rook. Black's queen, despite being active, cannot both defend the eighth rank AND stay safe from the rook's assault. The c6 pawn's capture is a desperado move that fails to generate sufficient counterplay because White's forcing sequence with checks gives Black no time to push f1=Q.

What to practice

In endgames with an active passed pawn, don't be lured into defensive captures that disrupt your piece coordination. Black's 2...Qxc6 seems logical—stop the c-pawn—but it removes the queen from central squares where it could defend critical lines. Recognize when your opponent can generate a forcing sequence (rook checks along the back rank) that paralyzes your pieces: a queen that must defend one square cannot also escape an incoming rook. The pattern: when your king is boxed in and your one active piece is required on defense, you're vulnerable to a forcing combination.

Tactical themes

crushing, endgame, very long. The key move Rxe8+ captures with check, forcing a response.
