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 d1, rook h3, bishop c2 d4, knight e3, pawn e2 f2 g2 h4 b5.
Black: king g8, queen g7, rook h6 c8, bishop a3 a8, knight e4 c6, pawn d5 h5 e6.
11 white and 11 black pieces are on the board; the puzzle position arises after move 24.
The position in numbers
Black are ahead by 6 points of material (28 against 34; 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 g8.
It is White to move on move 24, with 39 legal replies to weigh — only the line that keeps the advantage solves the puzzle.
White keeps 5 pawns, Black 3. Files fully open (no pawns of either colour): a, c — natural highways for the rooks and queen. Half-open for White: d.
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
24. Bxg7 Kxg7 25. bxc6
Why it works
- Great move! bishop to g7 keeps the pressure (+4.8).
- Spot on — pawn to c6 (+5.3).
- You win a piece — the queen.
- If instead Kxg7, then bxc6 and you win the queen.
Move by move
- 24. Bxg7 — bishop to g7 (capture)
- Kxg7 — king to g7 (capture)
- 25. bxc6 — pawn to c6 (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.
About this position
These pieces come from starting position #432.
SP-432 · RampartGuard — King on the wing (b/g) with both knights on inner files.
The king starts on g1, the rooks on c1 and h1, the queen on f1.
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: d2.
The setup belongs to the RampartGuard family; read right to left it becomes position 719.
The engine's main line opens with d4, putting a pawn straight into the centre.
