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.
Early Chess960 traps punish natural but careless development. Look for a forcing move that exploits a piece the opponent has just placed on a poor square — a fork, a pin or a threat that wins material before either side is fully developed.
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 f1, queen e2, rook a1 g1, bishop c1 h1, knight b1 e1, pawn a2 b2 d2 f2 g2 h2 c3.
Black: king g8, queen d8, rook a8 f8, bishop c8 h8, knight e5 d6, pawn a7 b7 c7 d7 e7 f7 g7 h7.
15 white and 16 black pieces are on the board; the puzzle position arises after move 5.
The position in numbers
Black are ahead by 1 points of material (38 against 39; pawn = 1, knight and bishop = 3, rook = 5, queen = 9) — the tactic has to convert or outweigh that.
The white king stands on f1, the black king on g8.
It is White to move on move 5, with 29 legal replies to weigh — only the line that keeps the advantage solves the puzzle.
White keeps 7 pawns, Black 8. No file is fully open, so the heavy pieces have to be pried in. Half-open for White: e.
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
5. Qxe5 g6 6. Qe2 e5 7. g3
Why it works
- Great move! queen to e5 keeps the pressure (+3.3).
- queen to e2 develops smoothly.
- A natural move: pawn to g3.
- You win a piece — the knight.
- If instead g6, then Qe2 and you win the knight.
Move by move
- 5. Qxe5 — queen 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.
Early trap
In the first moves of a fresh setup a trap already snaps shut.
An early trap is a tactic that snaps shut within the first moves: an unfamiliar setup hides shots that classical openings never produce. Examine every starting position with fresh eyes — which pieces already aim at each other, what hangs after the first pawn moves. Moves that feel "safe" from classical habit can lose on the spot here. Chess960 has no opening theory; it has alertness from move one.
About this position
These pieces come from starting position #423.
SP-423 · BastionGuard — King shifted to c or f, knights kept clear of the edges — 168 positions in all.
The king starts on f1, the rooks on a1 and g1, the queen on d1.
Castling short simply swaps the two pieces: the king on f1 and the rook on g1 trade places.
A bishop starts in the corner on h1: it has a single diagonal, which the g-pawn unlocks, running out to a8.
One second-rank pawn starts with no defender at all: h2.
The setup belongs to the BastionGuard family; read right to left it becomes position 722.
The engine's main line opens with d4, putting a pawn straight into the centre.
