Learn How to Win with a Fork: Middlegame Tactics

This puzzle is a classic middlegame tactic from the Queen's Gambit Declined: Marshall Defense, where active piece placement outweighs static material. The key idea is a fork that also creates a forcing check, so the defender’s king is dragged into a vulnerable square while major pieces become overloaded. In practical classical chess, these motifs often appear when one side’s queen and minor pieces coordinate against an exposed king and loose back-rank pieces.
