Chess Puzzle #50UjG — Beginner, Black to move, middlegame

Position

White: king g1; queen h6; rooks f1/h5; pawns a2/c4/c5/e5/g4/h2. Black: king g8; queen f6; rooks d4/e8; knight d3; pawns a7/b7/c6/f5/f7/g6. Black is ahead by 3 points of material. Black to move.

Solution (4 moves)

1. Opponent setup: exf6 — pawn e5→f6, captures queen. Now Black to move.
2. Best move: Rxg4+ — rook d4→g4, captures pawn, gives check. Opponent replies Kh1 (king g1→h1).
3. Best move: Nf2+ — knight d3→f2, gives check. Opponent replies Rxf2 (rook f1→f2, captures knight).
4. Best move: Re1+ — rook e8→e1, gives check. Opponent replies Rf1 (rook f2→f1).
5. Best move: Rxf1# — rook e1→f1, captures rook, delivers checkmate.

Why this works

White's setup move 32.exf6 removes Black's queen but fatally overextends the kingside. Black's 1...Rxg4+ forces the king to h1 (the only legal move). The knight then delivers 2...Nf2+, a discovery that forces 2.Rxf2 (the rook must interpose on f2). Black continues with 3...Re1+, checking the king again; White plays 3.Rf1 to block. The final 4...Rxf1# is checkmate because the king on h1 has no escape squares (g1 is controlled by the rook on f1, g2 is blocked by White's own pawn on h2, and h2 itself is occupied). The rook on h5 and queen on h6, intended to attack f7, are left powerless to defend the back rank.

What to practice

Recognize how an extended attack deep in opponent territory can leave the back rank undefended. This puzzle demonstrates the tempo-based mating pattern: Black trades material (knight and exchange of rooks) but forces a sequence of checks that reach the back rank before White can consolidate. When your opponent's king is forced to a corner, check lines to that corner — if they lead to the final rank, the attack may be unstoppable even if you've given up pieces along the way.

Tactical themes

endgame, kingside attack, mate, mate in 4, sacrifice, very long. The combination ends with Rxf1# delivering checkmate.
