Valencia Opening Other Variations Puzzle (Rated 1458): Win Material — Decisive Queen Tactic

This middlegame puzzle is about using queen activity to turn a large material edge into a forcing sequence. Black’s queen invades the king zone with check, creating immediate threats against the exposed white king and loose pieces. The key idea is that active checks can outweigh static material for a moment, especially when the opponent’s king is stuck in the center and several white pieces are passive or overloaded. The position rewards forcing play and precise calculation.
