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 h3, rook b7, knight g6, pawn g3 h4.
Black: king e8, rook c3, bishop f2, pawn f5 h5.
5 white and 5 black pieces are on the board; the puzzle position arises after move 47.
The position in numbers
Material is level — 10 points of pieces on each side (pawn = 1, knight and bishop = 3, rook = 5, queen = 9).
The white king stands on h3, the black king on e8.
It is Black to move on move 47, with 23 legal replies to weigh — only the line that keeps the advantage solves the puzzle.
White keeps 2 pawns, Black 2. Files fully open (no pawns of either colour): a, b, c, d, e — natural highways for the rooks and queen. Half-open for Black: g.
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
47... Rxg3+ 48. Kh2 Rxg6
Why it works
- Great move! rook to g3 keeps the pressure (+3.8).
- Well found: rook to g6 (+4.0).
- You win a piece — the knight.
- If instead Kh2, then Rxg6 and you win the knight.
Move by move
- 47… Rxg3+ — rook to g3 (capture) with check
- 48. Kh2 — king to h2
- Rxg6 — rook to g6 (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.
Win the pinned piece
The pinned piece cannot run — attack it again and win it.
A pinned piece cannot flee, which means you can win it outright by attacking it one more time. Count attackers against defenders: if you outnumber them, the piece is yours. The best extra attacker is a pawn, since it costs less than anything it might capture. Do not rush the capture — build up the pressure first, then harvest.
