Learn How to Win Material: Fork Tactic
This middlegame puzzle from the King's Indian Defense shows how a single forcing check can turn a material deficit into a decisive advantage. White’s queen becomes active with tempo, and the black king is pushed into a vulnerable square where the loose pieces and weak back rank coordination matter. The key idea is not a mating attack, but a tactical refutation that exploits the fork on the exposed knight and the overloaded defense around the king.
