What Is a Fork in Chess? (With Examples)
A fork is a double attack: one piece threatens two or more enemy pieces at the same time. Because the defender can only save one of them on their turn, the forking side usually wins material outright.
Knights are the classic forking piece thanks to their leaping move — a knight check that also hits a rook is the famous 'royal fork'. But every piece can fork: pawns fork when they advance to attack two pieces, and queens fork constantly because they attack in eight directions.
Forks appear most often after an unguarded piece wanders onto a square a cheap enemy piece can jump to. That's why checking whether your pieces defend each other is one of the cheapest habits that saves rating points.
Example position
White plays Nf3+ (or here, the knight on e2 can jump toward both the black queen on h5-side squares and the king): the knight lands on a square from which it attacks the black queen while giving check. Black must move the king, and White collects the queen — a textbook royal fork pattern.

- ✓ Look for enemy pieces that stand on the same color squares a knight can reach from one landing spot.
- ✓ Combine a check with an attack — a fork that includes the king wins material by force.
- ✓ Advance pawns toward loose enemy pieces; a pawn attacking a knight and bishop at once often wins a piece.
- ✓ Scan your opponent's last move for undefended pieces before choosing your own move.
How to defend against it
- ✗ Before every move, check whether any of your pieces are undefended (loose).
- ✗ Keep knights and bishops far enough apart that no single enemy piece can hit both.
- ✗ When you see an enemy knight, count which of your pieces sit on its possible landing squares.
- ✗ Avoid clustering valuable pieces next to the king — royal forks thrive there.
