Fork
Key Concept
One piece attacks two or more enemy pieces simultaneously
How This Tactic Works
A fork occurs when a single piece attacks two or more enemy pieces at the same time, forcing the opponent to lose material since they can only move one piece per turn. Knights are the most dangerous forking pieces because their L-shaped movement makes them difficult to anticipate. A knight fork on the king and queen (royal fork) wins the queen outright. Pawns, bishops, rooks, and queens can all fork as well. Recognizing fork opportunities — especially knight forks — is one of the most valuable tactical skills for players rated 800–1400.
How to Spot It
- →Enemy king and another valuable piece are on squares your knight can reach from one square
- →Two undefended pieces are placed on a diagonal, file, or rank your piece can attack simultaneously
- →After a trade or series of moves, a fork square becomes available
