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 e2, rook d1 b7, bishop g2, pawn b3 f3 g3 a4 e4.
Black: king h7, rook c5 d6, knight g4, pawn d4 c6 f6 g7.
9 white and 8 black pieces are on the board; the puzzle position arises after move 44.
The position in numbers
White are ahead by 1 points of material (18 against 17; pawn = 1, knight and bishop = 3, rook = 5, queen = 9) — the tactic has to convert or outweigh that.
The white king stands on e2, the black king on h7.
It is Black to move on move 44, with 26 legal replies to weigh — only the line that keeps the advantage solves the puzzle.
White keeps 5 pawns, Black 4. Files fully open (no pawns of either colour): h — natural highways for the rooks and queen. Half-open for Black: a, b, e.
The Black king has 4 empty squares to step to right now — the fewer they are, the closer a mating net.
Solution & explanation
Main line
44... d3+ 45. Ke1 Ne3 46. Rxd3 Rxd3
Why it works
- Great move! pawn to d3 keeps the pressure (+5.0).
- Well found: knight to e3 (+5.1).
- Strong! rook to d3 is the sharp choice (+5.0).
- You win a piece — the rook.
- If instead Ke1, then Ne3 and you stay on top.
Move by move
- 44… d3+ — pawn to d3 with check
- 45. Ke1 — king to e1
- Ne3 — knight to e3
- 46. Rxd3 — rook to d3 (capture)
- Rxd3 — rook to d3 (capture)
Types in this puzzle
Clearance
Clear your own piece out of the way — with tempo — for the decisive blow.
Clearance is about your own piece standing in the way of the decisive blow — so you move it aside, or even throw it away. The key is to clear with tempo: jump off with a check, a capture or a threat, giving the opponent no time to regroup. The telltale sign: you see a crushing queen or rook move, but one of your own pieces blocks the line or occupies the square. Do not cling to it — a clearance sacrifice usually costs less than a missed attack.
Passed pawn
Nothing can stop the passer — escort it to the last rank.
A passed pawn has no enemy pawns in front of it or on the neighboring files: only pieces can stop it. Check who can blockade the pawn or catch it with the king — if nobody can, the pawn is worth a whole piece. Push the passer with your pieces supporting it, and put your rook behind it. The beginner's mistake is shoving the pawn forward unprotected, straight into a capture.
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.
