Chess Puzzle #01tZ5 — Beginner, White to move, middlegame

Position

White: king g1; queen e3; rooks a1/g3; bishop f6; knight f5; pawns a2/b2/e4/f2/g2/h3. Black: king h7; queen c7; rooks b8/g8; bishop d6; knight e8; pawns b5/c6/e5/f7/g7/h5. Material is balanced. White to move.

Solution (3 moves)

1. Opponent setup: Nxf6 — knight e8→f6, captures bishop. Now White to move.
2. Best move: Rxg7+ — rook g3→g7, captures pawn, gives check. Opponent replies Rxg7 (rook g8→g7, captures rook).
3. Best move: Qh6+ — queen e3→h6, gives check. Opponent replies Kg8 (king h7→g8).
4. Best move: Qxg7# — queen h6→g7, captures rook, delivers checkmate.

Why this works

White's first move, 1.Rxg7+, is a rook sacrifice that forces Black's hand. The rook check on g7 compels 1...Rxg7 (the only legal move, since the king cannot move to g6 or h8). After 1...Rxg7, White plays 2.Qh6+, a queen check that drives the king to g8 (h8 is still controlled by the queen on h6, and the king cannot stay on h7). The final blow is 3.Qxg7#—the queen captures the rook with checkmate. The king on g8 has no escape squares: f7 is blocked by Black's own pawn, h7 and h8 are controlled by the queen on g7, and f8 is also controlled by the queen. The bishop on d6 and knight on f6 cannot interpose or defend. White's knight on f5 controls h6 and e7, sealing off two more escape routes and ensuring the mating net is complete.

What to practice

Recognize the attraction sacrifice pattern: when the opponent's rook or bishop is tied to defending a critical square (here, g7 was both a pawn and a key escape square), sacrificing a piece to force it to capture can lead to a fast mate. The second key is the follow-up check that herds the king into the corner—once the king is on g8, it's trapped by its own pawns. Practice spotting positions where your opponent's pieces are crammed on one side of the board with limited mobility; these are prime targets for forcing sequences.
