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.
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 g1, queen f8, rook h8, pawn b2 g2 a4 d4.
Black: king g6, queen e6, knight e4, pawn d5 c6 f6 a7 b7.
7 white and 8 black pieces are on the board; the puzzle position arises after move 36.
The position in numbers
White are ahead by 1 points of material (18 against 17; 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 g6.
It is White to move on move 36, with 31 legal replies to weigh — only the line that keeps the advantage solves the puzzle.
White keeps 4 pawns, Black 5. Files fully open (no pawns of either colour): e, h — natural highways for the rooks and queen. Half-open for White: c, f.
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
36. Qh6+ Kf5 37. Qh3+ Kf4 38. Qxe6
Why it works
- Great move! queen to h6 keeps the pressure (+7.6).
- Spot on — queen to h3 (+8.1).
- Precise: queen to e6 is the top choice (+8.3).
- You win a piece — the queen.
- If instead Kf5, then Qh3+ and you stay on top.
Move by move
- 36. Qh6+ — queen to h6 with check
- Kf5 — king to f5
- 37. Qh3+ — queen to h3 with check
- Kf4 — king to f4
- 38. Qxe6 — queen to e6 (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.
About this position
These pieces come from starting position #25.
SP-25 · RampartScout — A wing-file king (b or g) and at least one corner knight: the rarest of the six families, just 72 positions.
The king starts on g1, the rooks on f1 and h1, the queen on b1.
The king already stands on its castled square, so castling short moves only the rook, from h1 to f1.
The bishops stand on d1 and e1; their long diagonals reach h5 and a5 once the e- and d-pawns step aside.
The pawn on g2 is defended by the king alone — the same soft spot f2 is in the classical setup.
The setup belongs to the RampartScout family; read right to left it becomes position 937.
The engine's main line opens with h4.
Morozov Balance Index: 51 of 100 — class B — balanced. Engine evaluation of the starting position: +26 centipawns for White (depth 47, 400 000 000 nodes).
