The Fork: Attacking Two Pieces at Once
A Fork (or Double Attack) is one of the most deadly tactics in chess. It occurs when a single piece attacks two or more targets at the same time. Because the opponent can typically only save one piece per turn, the other target is often captured. Knights are especially famous for their forking ability!
