How to recognize this tactic
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.
From some Chess960 setups a bishop or queen rakes a long diagonal straight from move one. Trace those long-range lines into the enemy camp: a single opened file or diagonal can create an immediate pin, skewer or mating threat.
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.
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 c1, queen h1, rook a1 f1, bishop d1, knight e1, pawn b2 c2 d2 e2 h2 f4 g4.
Black: king b8, queen h8, rook f8, bishop d5 d8, knight d7 e8, pawn h5 f6 g6 b7 c7 e7.
13 white and 13 black pieces are on the board; the puzzle position arises after move 9.
The position in numbers
Material is level — 32 points of pieces on each side (pawn = 1, knight and bishop = 3, rook = 5, queen = 9).
The white king stands on c1, the black king on b8.
It is White to move on move 9, with 33 legal replies to weigh — only the line that keeps the advantage solves the puzzle.
White keeps 7 pawns, Black 6. Files fully open (no pawns of either colour): a — natural highways for the rooks and queen.
Black hold the bishop pair, an edge in open lines. The White king has 1 empty squares to step to right now — the fewer they are, the closer a mating net.
Solution & explanation

Why it works
- Great move! queen to d5 keeps the pressure (+3.9).
- Spot on — pawn to h5 (+3.7).
- A natural move: queen to e6.
- You win a piece — the bishop.
- If instead Nd6, then Qe6 and you win the bishop.
Move by move
- 9. Qxd5 — queen to d5 (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.
Long-range opener
From its unusual home square a long-range piece strikes across the board.
The long-range opener: a bishop, rook or queen strikes across the whole board straight from its starting area. In Chess960 the long-range pieces sit on unfamiliar squares, and a single pawn move can uncover a shot deep into the enemy camp. In the opening, trace with your eyes the diagonals and files of every long-range piece — yours and theirs. The mistake is pushing a pawn without checking whose line you have just opened.
Early queen raid
From an odd starting square the queen raids before defences exist.
The early queen raid: from an odd starting square the queen bursts into the game before any defense exists. In classical chess an early queen sortie gets punished, but in Chess960 it sometimes hits squares that literally no one can defend. The sign: within a move or two the queen reaches an unprotected pawn or piece near the enemy king. First check whether the queen can be chased with tempo — otherwise the raid just loses time.
About this position
These pieces come from starting position #285.
SP-285 · BastionScout — Off-centre king plus a rim knight (a/h): 168 positions carry this shape.
The king starts on c1, the rooks on b1 and f1, the queen on h1.
The king already stands on c1, so castling long moves only the rook, from b1 to d1.
The bishops stand on d1 and g1; their long diagonals reach h5 and a7 once the e- and f-pawns step aside.
One second-rank pawn starts with no defender at all: a2.
The setup belongs to the BastionScout family; read right to left it becomes position 584.
The engine's main line opens with a4.
