How do forks work in a chess puzzle?

A fork happens when one move attacks two valuable targets at the same time, such as a king and a queen or rook. In middlegame tactics, forks are easiest to find when enemy pieces are clustered or poorly defended.

Sicilian Defense Coles Sicilian Gambit Puzzle (Rated 1412): Win Material — Tactical Refutation
