Learn How to Fork: Decisive Material Gain
This puzzle comes from the Zukertort Opening, Slav Invitation, where active piece placement and king safety matter more than raw material. Black can exploit the exposed white king and the loose coordination of White’s minor pieces with a forcing check that creates a fork-like tactical sequence. The key idea is not a mating attack, but a decisive winning combination that wins material by using tempo, check, and piece overload. Recognizing when a checked king also exposes another valuable target is essential in classical chess.
