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 g2, rook b1 c8, knight f3, pawn f2 h2 g3.
Black: king g7, rook d3, bishop c5, knight e4, pawn e5 d6 g6 f7 h7.
7 white and 9 black pieces are on the board; the puzzle position arises after move 34.
The position in numbers
Material is level — 16 points of pieces on each side (pawn = 1, knight and bishop = 3, rook = 5, queen = 9).
The white king stands on g2, the black king on g7.
It is Black to move on move 34, with 30 legal replies to weigh — only the line that keeps the advantage solves the puzzle.
White keeps 3 pawns, Black 5. Files fully open (no pawns of either colour): a, b, c — natural highways for the rooks and queen.
The Black king has 2 empty squares to step to right now — the fewer they are, the closer a mating net.
Solution & explanation
Main line
34... Rxf3 35. Kxf3 Nd2+ 36. Ke2 Nxb1
Why it works
- Great move! rook to f3 keeps the pressure (+4.9).
- Well found: knight to d2 (+5.1).
- Strong! knight to b1 is the sharp choice (+5.0).
- You win a piece — the rook.
- If instead Kxf3, then Nd2+ and you stay on top.
Move by move
- 34… Rxf3 — rook to f3 (capture)
- 35. Kxf3 — king to f3 (capture)
- Nd2+ — knight to d2 with check
- 36. Ke2 — king to e2
- Nxb1 — knight to b1 (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.
Sacrifice attack
Give up material to unleash a decisive attack.
A sacrificial attack gives up material on purpose to rip the king's shelter open and launch a decisive assault. The sac is sound when you get concrete assets in return: open lines to the king, tempi, pieces ready to pour in. The signs: a poorly sheltered king, your forces aimed at its home, defenders stranded far away. The iron rule is to calculate, not hope — once the material is gone, there is no way back.
