The tactical motive
Save the piece: one of your pieces is attacked — find the best way to rescue it.

White to move — find the best continuation
How to recognize this tactic
Here the task is defensive: one of your pieces is under attack and must be rescued without losing more. Look for a move that saves it with tempo — a counter-check, an equal counter-attack or an interposition — rather than a passive retreat.
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 f2, queen g7, rook f1 e2, knight e5, pawn b2 g2 d4.
Black: king b8, queen a4, rook f4 h5, bishop b5, pawn c4 a7 b7 c7.
8 white and 9 black pieces are on the board; the puzzle position arises after move 31.
The position in numbers
Black are ahead by 1 points of material (25 against 26; pawn = 1, knight and bishop = 3, rook = 5, queen = 9) — the tactic has to convert or outweigh that.
The white king stands on f2, the black king on b8.
It is White to move on move 31, with 5 legal replies to weigh — only the line that keeps the advantage solves the puzzle. White are in check right now, so every reply must answer the check.
White keeps 3 pawns, Black 4. Files fully open (no pawns of either colour): e, f, h — natural highways for the rooks and queen. Half-open for White: a, c.
The White king has 4 empty squares to step to right now — the fewer they are, the closer a mating net.
Solution & explanation
Main line
31. Kg3 Qb3+ 32. Kxf4
Why it works
- Great move! king to g3 keeps the pressure (+3.5).
- Well found: king to f4 (+3.7).
- You win a piece — the rook.
- If instead Qb3+, then Kxf4 and you win the rook.
Move by move
- 31. Kg3 — king to g3
- Qb3+ — queen to b3 with check
- 32. Kxf4 — king to f4 (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.
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.
Save the piece
The attacked piece can be saved — with profit.
Saving the piece: one of your pieces is attacked, and the job is not to lose it for nothing. There are several tools: retreat with tempo, defend it, block the attack, or create a bigger counter-threat. Before retreating automatically, look for a retreat that attacks something — you save the piece and gain time in one move. The typical mistake is panicking onto the first available square, where the piece gets trapped again.
