Black to move — find the best continuation
How to recognize this tactic
Deflection drags a defender away from its duty. Identify the enemy piece that guards a key square or mate, then force it to move — with a check, a capture or a threat it must answer — and strike where it no longer defends.
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, rook g1 a8, pawn a5.
Black: king g6, rook g4, bishop e5, pawn f6.
4 white and 4 black pieces are on the board; the puzzle position arises after move 45.
The position in numbers
White are ahead by 2 points of material (11 against 9; 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 g6.
It is Black to move on move 45, with 22 legal replies to weigh — only the line that keeps the advantage solves the puzzle.
White keeps 1 pawns, Black 1. Files fully open (no pawns of either colour): b, c, d, e, g, h — natural highways for the rooks and queen. Half-open for Black: a.
The Black king has 7 empty squares to step to right now — the fewer they are, the closer a mating net.
Solution & explanation
Main line
45... Bd4+ 46. Kf3 Rxg1
Why it works
- Great move! bishop to d4 keeps the pressure (+3.7).
- Well found: rook to g1 (+3.6).
- You win a piece — the rook.
- If instead Kf3, then Rxg1 and you win the rook.
Move by move
- 45… Bd4+ — bishop to d4 with check
- 46. Kf3 — king to f3
- Rxg1 — rook to g1 (capture)
Types in this puzzle
Skewer
A line attack forces the valuable piece to move, exposing the one behind it.
A skewer is a pin turned inside out: the valuable piece stands in front and something cheaper hides behind it. The big piece must step aside, and you collect the one that was sheltering in its shadow. Scan for the enemy king or queen sharing a file, rank or diagonal with another enemy piece. The deadliest version comes with check — the king moves, the rook behind it dies.
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.
Endgame tactic
Tactics live in the endgame too — strike while material is scarce.
Tactics do not retire when the queens come off: forks, pins and double attacks live on in the endgame. With so little material left, every tactical loss is almost always decisive. The signs are the usual ones — undefended pieces, king and piece on one line, a pawn about to promote. Even in a "technical" ending, scan for a shot before every move, both yours and your opponent's.
