Fork

A fork occurs when one piece attacks two or more enemy pieces at the same time. Only one of the attacked units can be saved on the next move, so the attacker usually captures the remaining target and gains material.

Any piece can deliver a fork. Knights produce the most common examples because they jump and often strike targets that cannot protect each other. Pawns create forks when two enemy pieces stand on adjacent files one rank ahead; bishops, rooks, and queens fork along open diagonals, files, or ranks; even the king can fork when it attacks two undefended pieces in the endgame.

A fork that also checks the king is especially effective. The opponent must resolve the check first, frequently leaving the second target hanging.

The same pattern appears throughout the opening and middlegame. When two or more enemy pieces occupy squares a knight can reach in a single move, a fork is often available. Spotting these configurations early lets a player force favorable exchanges or win material outright.
