Learn How to Win Material: Fork Tactic
This middlegame puzzle comes from the Zukertort Opening, Tennison Gambit, where active queen play creates a forcing tactical sequence. The key idea is to use a checking move to drive the enemy king into a worse square while simultaneously targeting loose pieces. In positions like this, the side with the initiative can convert a small edge into decisive material gain by combining check, fork, and pressure on undefended targets.
