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, rook d1 d5, bishop f3, knight b3 h3, pawn a2 b2 f2 g2 h2 e3.
Black: king g8, queen c2, rook c8, bishop b4, knight c3, pawn f5 h6 a7 b7 f7.
12 white and 10 black pieces are on the board; the puzzle position arises after move 29.
The position in numbers
Material is level — 25 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 White to move on move 29, with 38 legal replies to weigh — only the line that keeps the advantage solves the puzzle.
White keeps 6 pawns, Black 5. Files fully open (no pawns of either colour): c, d — natural highways for the rooks and queen.
The White king has 0 empty squares to step to right now — the fewer they are, the closer a mating net.
Solution & explanation
Main line
29. R5d2 Nxd1 30. Rxc2 Rxc2 31. Bxd1
Why it works
- Great move! rook to d2 keeps the pressure (+4.5).
- Well found: rook to c2 (+4.9).
- Strong! bishop to d1 is the sharp choice (+4.8).
- You reach a winning position (+4.8).
- If instead Nxd1, then Rxc2 and you win the queen.

- 31. Bxd1 — bishop to d1 (capture)
Types in this puzzle
Decoy
A sacrifice lures the king or a piece onto a fatal square.
A decoy is the mirror image of deflection: you sacrifice to drag the king or a piece onto a fatal square. The classic is a queen or rook sac whose capture pulls the king into a knight fork, a discovered check or mate. Find the square where the target will be hit, then find the offer it cannot refuse. Calculate to the very end — a decoy only works when the follow-up is forced.
Remove the defender
Capture the guard first — then take what it protected.
Removing the defender is the straightforward plan: capture the guard first, then take what it guarded. Unlike deflection, the defender is not lured away — it is traded off or destroyed on the spot. Stare at the target you crave and ask who defends it, and whether that defender can be profitably eaten. Count the whole capture sequence, not just the first move — the trade must pay off at the end.
Queen trap
The strongest piece ventures too far — and cannot come back.
A queen trap catches the strongest piece after it ventures too far and finds no way home. The usual story is a queen grabbing a distant pawn — the classic poisoned pawn. The warning signs: the queen has few retreat squares, and enemy minor pieces cut them off one by one, gaining tempo with every move. Before your queen snacks on a pawn in enemy territory, count her escape routes — fewer than two means stay home.
