How to recognize this tactic
A fork is one piece attacking two targets at once. Look for a knight, pawn or queen move that lands where it hits the king (or a bigger piece) and a second undefended unit on the same turn — the opponent can save only one.
A pin freezes a piece in front of a more valuable one behind it. Scan the ranks, files and diagonals your bishop, rook or queen controls: if an enemy piece cannot move without exposing its king or queen, it is pinned and can be piled on or bypassed.
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 e2, queen d2, rook a1 g3, bishop d3, pawn a2 f3 d4 e5.
Black: king c8, queen h5, rook d7 e8, pawn d5 c6 f6 h6 a7 b7.
9 white and 10 black pieces are on the board; the puzzle position arises after move 28.
The position in numbers
White are ahead by 1 points of material (26 against 25; pawn = 1, knight and bishop = 3, rook = 5, queen = 9) — the tactic has to convert or outweigh that.
The white king stands on e2, the black king on c8.
It is Black to move on move 28, with 35 legal replies to weigh — only the line that keeps the advantage solves the puzzle.
White keeps 4 pawns, Black 6. Files fully open (no pawns of either colour): g — natural highways for the rooks and queen. Half-open for Black: e.
The Black king has 3 empty squares to step to right now — the fewer they are, the closer a mating net.
Solution & explanation
Main line
28... Qh2+ 29. Kd1 Qxg3
Why it works
- Great move! queen to h2 keeps the pressure (+4.9).
- Well found: queen to g3 (+4.9).
- You win a piece — the rook.
- If instead Kd1, then Qxg3 and you win the rook.
Move by move
- 28… Qh2+ — queen to h2 with check
- 29. Kd1 — king to d1
- Qxg3 — queen to g3 (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.
