Modern Defense Beefeater Variation Puzzle (Rated 982): Win Material — Tactical Refutation

This middlegame puzzle shows how a single defensive move can turn a dangerous attack into a winning material sequence. White’s active queen, rook, and knight create threats against the black king and loose pieces, but Black has a resource that changes the evaluation by forcing White’s queen to stay active while the attack loses momentum. The key idea is not to chase checks blindly, but to find the move that improves coordination and exploits a pinned or overloaded piece.
