Learn How to Win Material: Queen Fork
This puzzle shows a classic opening tactic in the Queen's Gambit Accepted: a queen check that also creates a fork on loose pieces. White has active pieces and a vulnerable king, but the key idea is not a mating attack. Instead, the forcing check drives the king or a defender into an awkward square, allowing the queen to win material on the next move. In classical chess, these short tactical sequences often decide the middlegame before development is complete.
