The tactical motive
Save the piece: one of your pieces is attacked — find the best way to rescue it.
Difficulty 1649 ShuffleRating — for advanced tacticians.
Black 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 g1, queen f3, rook a5, pawn b2 f2 g2 h2 a3.
Black: king b7, queen e6, rook f8, pawn d4 f7 h7.
8 white and 6 black pieces are on the board; the puzzle position arises after move 31.
The position in numbers
White are ahead by 2 points of material (19 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 b7.
It is Black to move on move 31, with 7 legal replies to weigh — only the line that keeps the advantage solves the puzzle. Black are in check right now, so every reply must answer the check.
White keeps 5 pawns, Black 3. Files fully open (no pawns of either colour): c, e — natural highways for the rooks and queen. Half-open for Black: a, b, g.
The Black king has 4 empty squares to step to right now — the fewer they are, the closer a mating net.
Solution & explanation
Main line
31... Kb6 32. g3 Kxa5
Why it works
- Great move! king to b6 keeps the pressure (+4.2).
- Well found: king to a5 (+4.3).
- You win a piece — the rook.
- If instead g3, then Kxa5 and you win the rook.
Move by move
- 31… Kb6 — king to b6
- 32. g3 — pawn to g3
- Kxa5 — king to a5 (capture)
Types in this puzzle
Winning blow
Find the strike that wins material by force.
A winning blow is a forced material gain that does not fit a single textbook motif. The general tactical recipe applies: spot loose pieces, an awkwardly placed king, overloaded lines. Go through the forcing moves in order of violence — checks, captures, threats — because most combinations start with one of them. Do not judge by feel: calculate the concrete line until the outcome is beyond doubt.
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.
