Learn How to Win Material: Queen's Gambit Declined Fork
This classical chess puzzle comes from the Queen's Gambit Declined, where active piece play matters more than slow pawn counting. Black has a tactical chance to exploit the exposed white king and the loose bishop on b7 by creating a forcing sequence with check and a fork-like idea. The position is an opening trap rather than a long chess endgame, and the key is to notice how one active queen move can win material while keeping White under pressure.
