Fork Puzzle (Rated 1640): Win with a Queen Fork — Middlegame Tactics

This puzzle is a classic middlegame tactical shot where a queen invasion creates immediate pressure on multiple loose pieces. The key idea is a fork: one powerful move attacks more than one target at once, forcing the opponent into a defensive sequence. In positions like this, material imbalances and an exposed king make tactical motifs far more dangerous than quiet strategic plans. Even if the position looks balanced at first glance, active pieces can suddenly decide the game.
