Chess Puzzle #0i69F — Beginner, Black to move, middlegame

Position

White: king f1; queen d1; rooks a1/e1; bishops c1/c6; knight d2; pawns a2/b2/c2/g2/h2. Black: king g8; queen h4; rooks a8/f8; bishops c5/f5; pawns a7/c7/d3/d5/f7/g7/h7. White is ahead by 1 point of material. Black to move.

Solution (1 move)

1. Opponent setup: Nf3 — knight d2→f3. Now Black to move.
2. Best move: Qf2# — queen h4→f2, delivers checkmate.

Why this works

1...Qf2 is checkmate because the black queen on f2 delivers check to the white king on f1, and the king has no escape squares or defenders. The e1 rook cannot interpose or capture the queen (it's pinned to the king by Black's bishop on c5 along the a3-f8 diagonal — moving the rook would leave the king in check from the bishop). The king cannot move to e1 (occupied by White's own rook), e2 (controlled by the queen on f2), g1 (controlled by the queen), or f2 (the queen is there). White's knight on f3, freshly moved, cannot reach f2 in time to block or capture. The queen is protected by Black's bishop on f5, which controls f2. White has no legal response.

What to practice

Recognize when an enemy rook is pinned to its own king and becomes a dead piece — it cannot defend its king's critical squares. Here, the e1 rook is helpless because moving it allows the bishop on c5 to give check. When you see a piece pinned along a line toward the enemy king, check whether you can exploit that pin with a forcing move (check or threat) that the pinned piece cannot answer.

Tactical themes

mate, mate in 1, middlegame, one move. The combination ends with Qf2# delivering checkmate.
