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 c8, bishop d4, pawn f2 h2 e3 g3.
Black: king f7, rook b4, bishop f8, pawn e4 d5 f5 g6 h7.
7 white and 8 black pieces are on the board; the puzzle position arises after move 37.
The position in numbers
Black are ahead by 1 points of material (12 against 13; pawn = 1, knight and bishop = 3, rook = 5, queen = 9) — the tactic has to convert or outweigh that.
The white king stands on g2, the black king on f7.
It is White to move on move 37, with 31 legal replies to weigh — only the line that keeps the advantage solves the puzzle.
White keeps 4 pawns, Black 5. Files fully open (no pawns of either colour): a, b, c — natural highways for the rooks and queen. Half-open for White: d.
The White king has 4 empty squares to step to right now — the fewer they are, the closer a mating net.
Solution & explanation
Main line
37. Rxf8+ Kxf8 38. Bc5+ Kf7 39. Bxb4
Why it works
- Great move! rook to f8 keeps the pressure (+4.0).
- Well found: bishop to c5 (+4.0).
- Strong! bishop to b4 is the sharp choice (+4.3).
- You win a piece — the rook.
- If instead Kxf8, then Bc5+ and you stay on top.
Move by move
- 37. Rxf8+ — rook to f8 (capture) with check
- Kxf8 — king to f8 (capture)
- 38. Bc5+ — bishop to c5 with check
- Kf7 — king to f7
- 39. Bxb4 — bishop to b4 (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.
Remove the defender
Capture the guard first — then take what it protected.
Removing the defender is the straightforward plan: capture the guard first, then take what it guarded. Unlike deflection, the defender is not lured away — it is traded off or destroyed on the spot. Stare at the target you crave and ask who defends it, and whether that defender can be profitably eaten. Count the whole capture sequence, not just the first move — the trade must pay off at the end.
