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 g1, queen a7, bishop g5, knight f3, pawn a2 b2 f2 g2 h3.
Black: king g8, queen c8, bishop f8, pawn b5 f5 a6 g6 h7.
9 white and 8 black pieces are on the board; the puzzle position arises after move 30.
The position in numbers
White are ahead by 3 points of material (20 against 17; pawn = 1, knight and bishop = 3, rook = 5, queen = 9) — the tactic has to convert or outweigh that.
The white king stands on g1, the black king on g8.
It is Black to move on move 30, with 27 legal replies to weigh — only the line that keeps the advantage solves the puzzle.
White keeps 5 pawns, Black 5. Files fully open (no pawns of either colour): c, d, 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
30... Bc5 31. Qxc5 Qxc5
Why it works
- Great move! bishop to c5 keeps the pressure (+4.5).
- Well found: queen to c5 (+4.4).
- You win a piece — the queen.
- If instead Qxc5, then Qxc5 and you win the queen.
Move by move
- 30… Bc5 — bishop to c5
- 31. Qxc5 — queen to c5 (capture)
- Qxc5 — queen to c5 (capture)
Types in this puzzle
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?
Only move
Everything else loses — find the only move that holds.
An only move is a position where everything loses except one single continuation. You cannot play "by hand" here: run through fundamentally different defenses — run away, block, trade, counterattack — and discard the ones that fail. The hallmark of these puzzles is that the obvious moves lose quickly while the solution often looks strange. First understand exactly what the threat is — then the one saving move reveals itself.
