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 b1, queen d4, rook b2, knight d5, pawn e2 c3 h4 a6.
Black: king f8, queen g6, rook c8, knight b6, pawn d3 a7 f7.
8 white and 7 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 (21 against 20; pawn = 1, knight and bishop = 3, rook = 5, queen = 9) — the tactic has to convert or outweigh that.
The white king stands on b1, the black king on f8.
It is White to move on move 36, with 38 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): b, g — natural highways for the rooks and queen. Half-open for White: d, 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. Qh8+ Qg8 37. Qxg8+ Kxg8 38. Ne7+ Kg7 39. Nxc8
Why it works
- Great move! queen to h8 keeps the pressure (+5.3).
- Spot on — queen to g8 (+5.5).
- Strong! knight to e7 is the sharp choice (+6.0).
- Great move! knight to c8 keeps the pressure (+6.2).
- You win a piece — the queen.
- If instead Qg8, then Qxg8+ and you win the queen.
Move by move
- 36. Qh8+ — queen to h8 with check
- Qg8 — queen to g8
- 37. Qxg8+ — queen to g8 (capture) with check
- Kxg8 — king to g8 (capture)
- 38. Ne7+ — knight to e7 with check
- Kg7 — king to g7
- 39. Nxc8 — knight to c8 (capture)
Types in this puzzle
Royal fork
A fork with check: the king must move, and the second piece is lost.
A royal fork is a fork with check — one of the two targets is the king itself. The check must be answered first, so nobody is left to rescue the second piece. Look for squares where your piece gives check and simultaneously attacks an undefended queen or rook. It is the most reliable fork of all, because your opponent literally has no choice.
Simplification
Trade the heavy pieces and steer into a won endgame.
Simplification is how you convert an advantage: by trading queens and rooks you extinguish the counterplay and steer the game into a won endgame. The rule is simple — the side with extra material trades pieces but keeps pawns. Look for exchanges once the material is already won and your opponent is still rattling threats. The mistake is avoiding the queen trade and letting him muddy the water forever.
Win the pinned piece
The pinned piece cannot run — attack it again and win it.
A pinned piece cannot flee, which means you can win it outright by attacking it one more time. Count attackers against defenders: if you outnumber them, the piece is yours. The best extra attacker is a pawn, since it costs less than anything it might capture. Do not rush the capture — build up the pressure first, then harvest.
About this position
These pieces come from starting position #761.
SP-761 · RampartGuard — A wing king (b/g) with no knight on the a- or h-file.
The king starts on b1, the rooks on a1 and g1, the queen on h1.
From b1 the king makes the longest journey Chess960 allows when castling short: five squares to g1.
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 b2 is defended by the king alone — the same soft spot f2 is in the classical setup.
The setup belongs to the RampartGuard family; read right to left it becomes position 393.
The engine's main line opens with a4.
Morozov Balance Index: 69 of 100 — class B — balanced. Engine evaluation of the starting position: +21 centipawns for White (depth 43, 400 000 000 nodes).
