Black 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 f4, bishop f2, pawn c3 a4 h4.

Black: king f6, knight c5, pawn d5 h5 a6.

5 white and 5 black pieces are on the board; the puzzle position arises after move 47.

The position in numbers

Material is level — 6 points of pieces on each side (pawn = 1, knight and bishop = 3, rook = 5, queen = 9).

The white king stands on f4, the black king on f6.

It is Black to move on move 47, with 14 legal replies to weigh — only the line that keeps the advantage solves the puzzle.

White keeps 3 pawns, Black 3. Files fully open (no pawns of either colour): b, e, f, g — natural highways for the rooks and queen. Half-open for Black: c.

The Black king has 5 empty squares to step to right now — the fewer they are, the closer a mating net.

Solution & explanation

Main line

47... Nd3+ 48. Ke3 Nxf2

Why it works

  • Great move! knight to d3 keeps the pressure (+4.9).
  • Well found: knight to f2 (+5.3).
  • You win a piece — the bishop.
  • If instead Ke3, then Nxf2 and you win the bishop.

Move by move

  • 47… Nd3+ — knight to d3 with check
  • 48. Ke3 — king to e3
  • Nxf2 — knight to f2 (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.

Minor-piece endgame

Bishops and knights duel — geometry decides.

A minor-piece endgame leaves only bishops and knights with pawns, and geometry decides. The bishop loves an open board and play on both wings; the knight loves fixed pawns and outpost squares. Check which color squares the pawns stand on and where the knight can actually reach in time. Practical tip: against a knight, spread the play across both flanks — short legs cannot cover everything.
