Learn How to Fork: Decisive Material Gain
This middlegame puzzle shows how a single active queen can create a forcing tactical sequence when the enemy king is exposed and key pieces are loose. The main idea is not a mating attack, but a decisive material gain through check, tempo, and a fork-like tactical refutation. When pieces are uncoordinated, a forcing move can win a major piece and keep the initiative. Look for checks that also attack something valuable on the next move.
