White to move — find the best continuation
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 g1, queen d5, rook d1 e1, knight d6, pawn a2 b2 g2 h2 c3 f4.
Black: king h8, queen g6, rook d8 f8, knight f7, pawn c5 f5 a6 b6 h6 g7.
11 white and 11 black pieces are on the board; the puzzle position arises after move 30.
The position in numbers
Material is level — 28 points of pieces on each side (pawn = 1, knight and bishop = 3, rook = 5, queen = 9).
The white king stands on g1, the black king on h8.
It is White to move on move 30, with 49 legal replies to weigh — only the line that keeps the advantage solves the puzzle.
White keeps 6 pawns, Black 6. Files fully open (no pawns of either colour): d, e — natural highways for the rooks and queen.
The White king has 3 empty squares to step to right now — the fewer they are, the closer a mating net.
Solution & explanation
Main line
30. Nxf7+ Qxf7 31. Qxf7 Rxf7 32. Rxd8+
Why it works
- Great move! knight to f7 keeps the pressure (+6.1).
- Well found: queen to f7 (+6.4).
- Strong! rook to d8 is the sharp choice (+6.6).
- You win a piece — the queen.
- If instead Qxf7, then Qxf7 and you win the queen.
Move by move
- 30. Nxf7+ — knight to f7 (capture) with check
- Qxf7 — queen to f7 (capture)
- 31. Qxf7 — queen to f7 (capture)
- Rxf7 — rook to f7 (capture)
- 32. Rxd8+ — rook to d8 (capture) with check
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.
Simplification
Trade the heavy pieces and steer into a won endgame.
Simplification is how you convert an advantage: by trading queens and rooks you extinguish the counterplay and steer the game into a won endgame. The rule is simple — the side with extra material trades pieces but keeps pawns. Look for exchanges once the material is already won and your opponent is still rattling threats. The mistake is avoiding the queen trade and letting him muddy the water forever.
Discovered attack
A piece steps aside and opens a second attack from the piece behind it.
A discovered attack works like a curtain: one piece steps off the line and unveils the long-range piece behind it. The beauty is that the moving piece can create a second threat of its own — two attacks in one move. Look for your stacked pairs: a bishop or rook behind a knight or pawn, aimed through them at something valuable. Send the front piece to the most aggressive square — a discovery without a second threat wastes half its power.
