Learn How to Win a Fork: Endgame Material Gain
This chess endgame puzzle shows how a single active rook can create a decisive material gain by attacking two loose pieces at once. The key idea is a fork: one move forces the king to respond while also winning an undefended piece. In simplified positions, hanging pieces become especially vulnerable because there are fewer defenders and less counterplay. Strong players look for forcing moves first, then convert the extra material cleanly.
