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.
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 c1, queen g3, rook h1, bishop c5, pawn a2 b2 c2 g2 h2.
Black: king g8, queen d8, rook a8, knight d4, pawn b4 a6 f7 g7 h7.
9 white and 9 black pieces are on the board; the puzzle position arises after move 22.
The position in numbers
Material is level — 22 points of pieces on each side (pawn = 1, knight and bishop = 3, rook = 5, queen = 9).
The white king stands on c1, the black king on g8.
It is Black to move on move 22, with 34 legal replies to weigh — only the line that keeps the advantage solves the puzzle.
White keeps 5 pawns, Black 5. Files fully open (no pawns of either colour): d, e — natural highways for the rooks and queen. Half-open for Black: c.
The Black king has 1 empty squares to step to right now — the fewer they are, the closer a mating net.
Solution & explanation
Main line
22... Ne2+ 23. Kb1 Nxg3
Why it works
- Great move! knight to e2 keeps the pressure (+6.5).
- Well found: knight to g3 (+6.6).
- You win a piece — the queen.
- If instead Kb1, then Nxg3 and you win the queen.
Move by move
- 22… Ne2+ — knight to e2 with check
- 23. Kb1 — king to b1
- Nxg3 — knight 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.
