How to recognize this tactic
A trapped piece has no safe square. Spot an enemy piece that has wandered offside or been hemmed in, then play the move that takes away its last escape and wins it — often a quiet pawn push or a covering minor piece.
General method: before you move, list the forcing candidates — every check, every capture, every direct threat — and calculate those first. The solution to a tactic is almost always among them.
Position on the board
White: king a1, queen g6, rook e1, bishop d2, knight e6, pawn a2 b2 g2 h2 f3 d4.
Black: king g8, queen b5, rook f7, bishop d3, knight f6, pawn a4 b4 d5 f5 h6 g7.
11 white and 11 black pieces are on the board; the puzzle position arises after move 31.
The position in numbers
Material is level — 26 points of pieces on each side (pawn = 1, knight and bishop = 3, rook = 5, queen = 9).
The white king stands on a1, the black king on g8.
It is Black to move on move 31, with 33 legal replies to weigh — only the line that keeps the advantage solves the puzzle.
White keeps 6 pawns, Black 6. Files fully open (no pawns of either colour): c, e — natural highways for the rooks and queen.
The Black king has 1 empty squares to step to right now — the fewer they are, the closer a mating net.
Solution & explanation
Main line
31... f4 32. Qxf7+ Kxf7
Why it works
- Great move! pawn to f4 keeps the pressure (+4.5).
- Well found: king to f7 (+5.0).
- You win a piece — the queen.
- If instead Qxf7+, then Kxf7 and you win the queen.
Move by move
- 31… f4 — pawn to f4
- 32. Qxf7+ — queen to f7 (capture) with check
- Kxf7 — king to f7 (capture)
Types in this puzzle
Discovered attack
A piece steps aside and opens a second attack from the piece behind it.
A discovered attack works like a curtain: one piece steps off the line and unveils the long-range piece behind it. The beauty is that the moving piece can create a second threat of its own — two attacks in one move. Look for your stacked pairs: a bishop or rook behind a knight or pawn, aimed through them at something valuable. Send the front piece to the most aggressive square — a discovery without a second threat wastes half its power.
Quiet move
No check, no capture — yet this modest move decides the game.
A quiet move gives no check and takes nothing — yet it decides the game by creating an unstoppable threat or stealing the king's last square. This is the hardest class of moves: the eye hunts for loud blows while a modest shift does the winning. The clue: every forcing try runs into a defense, so seek the move that strengthens the threat or takes squares away. Train yourself to ask: what if I neither capture nor check, but quietly improve?
