The tactical motive
Save the piece: one of your pieces is attacked — find the best way to rescue it.
Difficulty 1965 ShuffleRating — for advanced tacticians.
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 g1, rook f8, pawn g2 h3 d6 e7.
Black: king h7, queen c5, pawn b5 h6 a7 g7.
6 white and 6 black pieces are on the board; the puzzle position arises after move 42.
The position in numbers
Black are ahead by 4 points of material (9 against 13; 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 h7.
It is White to move on move 42, with 4 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 4 pawns, Black 4. Files fully open (no pawns of either colour): c, f — natural highways for the rooks and queen. Half-open for White: a, b.
The White king has 3 empty squares to step to right now — the fewer they are, the closer a mating net.
Solution & explanation
Main line
42. Kh1 Qxd6 43. e8=Q Qd1+ 44. Kh2
Why it works
- Great move! king to h1 keeps the pressure (+5.6).
- Well found: pawn to e8 (+5.8).
- Strong! king to h2 is the sharp choice (+6.0).
- You win decisive material (+6.0).
- If instead Qxd6, then e8=Q and you win the pawn.
Move by move
- 42. Kh1 — king to h1
- Qxd6 — queen to d6 (capture)
- 43. e8=Q — pawn to e8
- Qd1+ — queen to d1 with check
- 44. Kh2 — king to h2
Types in this puzzle
Promotion
The pawn reaches the last rank and becomes a queen — decisively.
Promotion turns a pawn on the last rank into a queen and rewrites the evaluation on the spot. In tactics the passer rarely walks in for free — usually a sacrifice clears its path. Count the tempi: how many moves does the pawn need, and can the defender stop it in time? And watch the promotion square itself — it must be out of enemy reach or won by force in your combination.
Promotion race
Both sides push passers — win the race by a tempo.
A promotion race is a sprint between two passed pawns: both sides push toward the last rank, and victory goes to whoever queens first or queens with check. You will recognize it when both players have far-advanced passers that neither king can catch. Count the tempi literally, move by move, all the way to promotion. The classic mistake is spending a tempo on a "useful" move — in a race, almost any non-pawn move loses.
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.
