The fork

One piece, two targets.

A fork is a single piece attacking two targets at once. The opponent can only save one — so you win the other. The knight is the great forker because it jumps to squares no other piece guards, but any piece can fork.

Forks are deadliest with check: if one of the two targets is the king, the opponent MUST answer the check, leaving the second target to be captured next move.

  • Fork = one piece attacks two things; only one can escape.
  • The knight is the classic forker.
  • A fork WITH check is strongest — the king must move first.
The knight on d5 attacks both rooks at once — one of them will fall.

Why can't Black save both rooks in the diagram?
