How to recognize this tactic
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.
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.
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 c2, queen b8, rook b1 h1, bishop d3, knight a1 f3, pawn a2 d2 h2 g3 f4.
Black: king e7, queen c4, rook h8, bishop c8, knight d6, pawn c5 g5 a6 b6 d7 h7.
12 white and 11 black pieces are on the board; the puzzle position arises after move 16.
The position in numbers
White are ahead by 7 points of material (33 against 26; pawn = 1, knight and bishop = 3, rook = 5, queen = 9) — the tactic has to convert or outweigh that.
The white king stands on c2, the black king on e7.
It is White to move on move 16, with 3 legal replies to weigh — only the line that keeps the advantage solves the puzzle. White are in check right now, so every reply must answer the check.
White keeps 5 pawns, Black 6. Files fully open (no pawns of either colour): e — natural highways for the rooks and queen. Half-open for White: b, c.
The White king has 2 empty squares to step to right now — the fewer they are, the closer a mating net.
Solution & explanation
Main line
16. Bxc4 Nxc4 17. Rhe1+ Kf7 18. Nxg5+
Why it works
- Great move! bishop to c4 keeps the pressure (+11.3).
- Well found: rook to e1 (#10).
- Precise: knight to g5 is the top choice (+10.7).
- You win a piece — the queen.
- If instead Bb7, then Rhe1+ and you win the queen.
Move by move
- 16. Bxc4 — bishop to c4 (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.
