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 h2, queen h6, knight h3, pawn g2 a4 c5 e5.
Black: king g8, rook a1 f8, knight c8, pawn d3 b6 a7.
7 white and 7 black pieces are on the board; the puzzle position arises after move 33.
The position in numbers
Material is level — 16 points of pieces on each side (pawn = 1, knight and bishop = 3, rook = 5, queen = 9).
The white king stands on h2, the black king on g8.
It is White to move on move 33, with 28 legal replies to weigh — only the line that keeps the advantage solves the puzzle.
White keeps 4 pawns, Black 3. Files fully open (no pawns of either colour): f, h — natural highways for the rooks and queen. Half-open for White: b, d.
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
33. Qg6+ Kh8 34. Ng5 Rh1+ 35. Kxh1
Why it works
- Great move! queen to g6 keeps the pressure (#5).
- knight to g5 develops smoothly.
- Strong! king to h1 is the sharp choice (#3).
- You win a piece — the rook.
- If instead Kh8, then Ng5 and you stay on top.
Move by move
- 33. Qg6+ — queen to g6 with check
- Kh8 — king to h8
- 34. Ng5 — knight to g5
- Rh1+ — rook to h1 with check
- 35. Kxh1 — king to h1 (capture)
Types in this puzzle
Winning blow
Find the strike that wins material by force.
A winning blow is a forced material gain that does not fit a single textbook motif. The general tactical recipe applies: spot loose pieces, an awkwardly placed king, overloaded lines. Go through the forcing moves in order of violence — checks, captures, threats — because most combinations start with one of them. Do not judge by feel: calculate the concrete line until the outcome is beyond doubt.
Queen endgame
Queens on an open board — precision above all.
Queen endgames are treacherous: the queen reaches everywhere, and one slip turns a win into perpetual check. The signs are few pawns, exposed kings, and checks hanging in the air. Tuck your king away early, and use your own checks to bring the queen closer or push your passer with tempo. The typical mistake is grabbing pawns while leaving your king exposed to endless checks.
About this position
These pieces come from starting position #50.
SP-50 · RampartGuard — A b- or g-file king and two knights on inner files (b–g).
The king starts on g1, the rooks on d1 and h1, the queen on e1.
The king already stands on its castled square, so castling short moves only the rook, from h1 to f1.
A bishop starts in the corner on a1: it has a single diagonal, which the b-pawn unlocks, running out to h8.
One second-rank pawn starts with no defender at all: c2.
The setup belongs to the RampartGuard family; read right to left it becomes position 903.
The engine's main line opens with e4, putting a pawn straight into the centre.
Morozov Balance Index: 37 of 100 — class C — noticeable edge. Engine evaluation of the starting position: +30 centipawns for White (depth 45, 400 000 000 nodes).
