The tactical motive
Hanging piece: your opponent left a piece undefended — take it.

How to recognize this tactic
A hanging piece is one that is attacked and not defended, or defended too few times. Count attackers against defenders on each enemy unit; where attackers win, take it — often with an in-between move or a check to gain the extra tempo.
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 e3, queen c5, rook a1 d1, bishop c1, knight d6, pawn a2 b2 f2 g2 e4.
Black: king g8, queen g4, rook e6 d8, pawn a6 b7 f7 g7 h7.
11 white and 9 black pieces are on the board; the puzzle position arises after move 24.
The position in numbers
White are ahead by 6 points of material (30 against 24; pawn = 1, knight and bishop = 3, rook = 5, queen = 9) — the tactic has to convert or outweigh that.
The white king stands on e3, the black king on g8.
It is Black to move on move 24, with 39 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 — natural highways for the rooks and queen. Half-open for Black: e.
The Black king has 2 empty squares to step to right now — the fewer they are, the closer a mating net.
Solution & explanation
Main line
24... Qxd1 25. Bd2 Qxa1
Why it works
- Great move! queen to d1 keeps the pressure (+5.1).
- Well found: queen to a1 (+5.1).
- You win a piece — the rook.
- If instead Bd2, then Qxa1 and you win the rook.
Move by move
- 24… Qxd1 — queen to d1 (capture)
- 25. Bd2 — bishop to d2
- Qxa1 — queen to a1 (capture)
Types in this puzzle
Relative pin
A piece shields a more valuable one behind it — moving it loses material.
In a relative pin the piece shields not its king but something valuable behind it, usually the queen. Moving is legal but costly, because the piece behind falls. Look for three units on one line: your long-range piece, a cheaper enemy piece, and an expensive one hiding behind. Beware the classic trap — a relatively pinned piece can still move with check or a bigger threat, so verify before you cash in.
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.
