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 h5, knight d4, pawn a3 b4 f4 f5 g6.
Black: king g7, rook d8, pawn d5 a6 f6.
7 white and 5 black pieces are on the board; the puzzle position arises after move 51.
The position in numbers
Material is level — 8 points of pieces on each side (pawn = 1, knight and bishop = 3, rook = 5, queen = 9).
The white king stands on h5, the black king on g7.
It is White to move on move 51, with 11 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): c, e, h — natural highways for the rooks and queen. Half-open for White: d.
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
51. Ne6+ Kg8 52. Nxd8
Why it works
- Great move! knight to e6 keeps the pressure (+6.4).
- Well found: knight to d8 (+6.5).
- You win a piece — the rook.
- If instead Kg8, then Nxd8 and you win the rook.
Move by move
- 51. Ne6+ — knight to e6 with check
- Kg8 — king to g8
- 52. Nxd8 — knight to d8 (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.
Endgame tactic
Tactics live in the endgame too — strike while material is scarce.
Tactics do not retire when the queens come off: forks, pins and double attacks live on in the endgame. With so little material left, every tactical loss is almost always decisive. The signs are the usual ones — undefended pieces, king and piece on one line, a pawn about to promote. Even in a "technical" ending, scan for a shot before every move, both yours and your opponent's.
