White to move — find the best continuation
How to recognize this tactic
This position hides a concrete tactic that wins material or mates. Start with the most forcing candidate moves — checks, captures and threats — and calculate each to a clear end before choosing; the winning line is usually the one the opponent cannot meet.
In Chess960 the pieces start on unfamiliar squares, so tactics appear earlier and from unusual angles. Do not trust classical patterns — read the actual lines of the bishops, the rooks and the queen from where they really stand in this position.
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 a1, rook d1 g1, bishop f1, knight h1 b3, pawn a2 b2 f2 g2 h2 d4.
Black: king b8, queen e5, rook c8 f8, bishop d7, pawn f4 h5 b6 a7 b7 g7.
12 white and 11 black pieces are on the board; the puzzle position arises after move 18.
The position in numbers
Black are ahead by 3 points of material (25 against 28; pawn = 1, knight and bishop = 3, rook = 5, queen = 9) — the tactic has to convert or outweigh that.
The white king stands on a1, the black king on b8.
It is White to move on move 18, with 25 legal replies to weigh — only the line that keeps the advantage solves the puzzle.
White keeps 6 pawns, Black 6. Files fully open (no pawns of either colour): c, e — natural highways for the rooks and queen.
The White king has 1 empty squares to step to right now — the fewer they are, the closer a mating net.
Solution & explanation
Main line
18. dxe5 Rfd8 19. Bd3 a5 20. Be4
Why it works
- Great move! pawn to e5 keeps the pressure (+5.9).
- bishop to d3 develops smoothly.
- A natural move: bishop to e4.
- You win a piece — the queen.
- If instead Rfd8, then Bd3 and you win the queen.
Move by move
- 18. dxe5 — pawn to e5 (capture)
Types in this puzzle
Hanging piece
A piece is left without protection — just take it.
A hanging piece is simply an unprotected piece you can take for free. It sounds primitive, yet most amateur games are decided exactly this way. Build the habit: before every move, sweep the board and note every undefended piece, yours and theirs. The classic mistake is hunting for a brilliant combination when all you need to do is bend down and pick up the gift.
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.
