Queens Gambit Declined Alapin Variation Puzzle (Rated 1421): Win Material — Queen Fork

This puzzle shows a classic middlegame tactical idea from the Queen's Gambit Declined: using an active queen to create a forcing check that also wins material. White’s pieces are more active, and the black bishop on b4 is tied to the pressure around the white knight and king. The key is to notice how a checking move can force a defensive reply while keeping the opponent’s loose piece under attack. That combination of tempo and target is what turns a small initiative into a decisive material gain.
