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 e1, rook c1 g1, bishop g7, knight b1 f1, pawn c2 f2 h2 a3 d3 e3 h6.
Black: king d8, queen g6, rook c8 g8, bishop a8 f8, knight c6, pawn b6 e6 a7 c7 d7.
13 white and 12 black pieces are on the board; the puzzle position arises after move 14.
The position in numbers
Black are ahead by 7 points of material (26 against 33; pawn = 1, knight and bishop = 3, rook = 5, queen = 9) — the tactic has to convert or outweigh that.
The white king stands on e1, the black king on d8.
It is White to move on move 14, with 33 legal replies to weigh — only the line that keeps the advantage solves the puzzle.
White keeps 7 pawns, Black 5. Files fully open (no pawns of either colour): g — natural highways for the rooks and queen. Half-open for White: b.
Black hold the bishop pair, an edge in open lines. The White king has 4 empty squares to step to right now — the fewer they are, the closer a mating net.
Solution & explanation
Main line
14. Rxg6 Bxg7 15. h7 Rh8 16. Rxg7
Why it works
- Great move! rook to g6 keeps the pressure (+2.5).
- pawn to h7 develops smoothly.
- Strong! rook to g7 is the sharp choice (+3.2).
- You win a piece — the queen.
- If instead Bxg7, then h7 and you win the queen.
Move by move
- 14. Rxg6 — rook to g6 (capture)
- Bxg7 — bishop to g7 (capture)
- 15. h7 — pawn to h7
- Rh8 — rook to h8
- 16. Rxg7 — rook to g7 (capture)
Types in this puzzle
Remove the defender
Capture the guard first — then take what it protected.
Removing the defender is the straightforward plan: capture the guard first, then take what it guarded. Unlike deflection, the defender is not lured away — it is traded off or destroyed on the spot. Stare at the target you crave and ask who defends it, and whether that defender can be profitably eaten. Count the whole capture sequence, not just the first move — the trade must pay off at the end.
About this position
These pieces come from starting position #273.
SP-273 · ThroneGuard — Both knights start on inner files (b–g) while the king sits centrally on d or e — one of 204 positions filed here.
The king starts on e1, the rooks on c1 and g1, the queen on h1.
Castling ends where it always does: king to g1 and rook to f1 on the short side, king to c1 and rook to d1 on the long one.
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: a2.
The setup belongs to the ThroneGuard family; read right to left it becomes position 587.
The engine's main line opens with g4.
Morozov Balance Index: 7 of 100 — class D — largest edge. Engine evaluation of the starting position: +46 centipawns for White (depth 48, 400 000 000 nodes).
