The fork

One piece, two targets — and the knight that hits both from a square nothing defends.

One piece, two targets. Your opponent can only save one.

The knight is the king of forks, for a precise reason: it attacks squares no other piece can defend from where it stands. A rook attacked by a rook can be protected; a rook attacked by a knight has to run.

The most profitable fork is called the family fork: the knight attacks the king and a heavy piece at the same time. The king must answer the check — he has no choice — and the piece falls next move.

Demonstration — use the arrows

Move list

    Start

    The family fork. The knight jumps to c7: check to the king on e8, and the rook on a8 is attacked. The king must move, the rook falls.

    How to spot them: look for squares from which a knight would touch two enemy pieces. With practice you see them before calculating. And above all — look for the squares where your opponent could do the same to you. A king and a queen on the same colour, a knight’s jump apart, is a fork waiting to happen.

    You can practise it in the knight fork exercise.

    Play your move on the board: drag a piece, or tap it and then tap its destination square.

    Standard notation (Bc4, Nxe5, O-O) or plain squares (f1c4). French piece letters work too: R king, D queen, T rook, F bishop, C knight.

    Win the rook.
