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 c2, bishop h5, knight e7, pawn h2 a4 g4 f7.
Black: king g5, rook f8, bishop f6, pawn c3 b4 h6.
7 white and 6 black pieces are on the board; the puzzle position arises after move 52.
The position in numbers
Black are ahead by 1 points of material (10 against 11; pawn = 1, knight and bishop = 3, rook = 5, queen = 9) — the tactic has to convert or outweigh that.
The white king stands on c2, the black king on g5.
It is White to move on move 52, with 15 legal replies to weigh — only the line that keeps the advantage solves the puzzle.
White keeps 4 pawns, Black 3. Files fully open (no pawns of either colour): d, e — natural highways for the rooks and queen. Half-open for White: b, c.
The White king has 5 empty squares to step to right now — the fewer they are, the closer a mating net.
Solution & explanation
Main line
52. h4+ Kf4 53. Ng6+ Ke3 54. Nxf8
Why it works
- Great move! pawn to h4 keeps the pressure (+5.8).
- Well found: knight to g6 (+6.3).
- Strong! knight to f8 is the sharp choice (+6.7).
- You win a piece — the rook.
- If instead Kf4, then Ng6+ and you stay on top.
Move by move
- 52. h4+ — pawn to h4 with check
- Kf4 — king to f4
- 53. Ng6+ — knight to g6 with check
- Ke3 — king to e3
- 54. Nxf8 — knight to f8 (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.
Breakthrough
A pawn sacrifice tears the chain open and lets a passer through.
A breakthrough is a pawn sacrifice that rips the opponent's chain open and creates an unstoppable passer. Look for it where the pawns are locked against each other: often two pawns are given up so the third one slips through. Check the square rule — can the enemy king catch the new passer? If not, sacrifice with confidence; the classic error is breaking through while his king stands right there eating everything.
Counter-strike
Don't defend — answer the threat with a bigger one.
The counter-strike: instead of defending against the threat, you answer with a bigger threat of your own. While your opponent grabs a pawn, you deliver mate — the arithmetic favors you. Look for a counter when direct defenses fail: do you have a check, an attack on the queen, a mating threat? The beginner's error is meeting every threat with a reflexive defense without checking the counterattacking resources first.
