Fork puzzles

A fork is one piece attacking two targets at once. The opponent can only save one, so you win the other.

Knights are famous for it, but queens, pawns, bishops and even kings fork too. The best forks include the king - a check that also hits a loose piece.

How to spot it

• Look for two loose pieces, or a loose piece and the king, that one piece could reach together.
• Knight forks hide well: trace the L-shapes from every square near the targets.
• Sometimes the first move forces a piece onto a forkable square.
