Dutch Defense Queens Knight Variation Pin Puzzle (Rated 1147): Crush a Pin — Decisive Material Gain

This middlegame puzzle is built around a classic pin tactic that turns active piece placement into a decisive material gain. White’s bishop is ideally placed to create a direct tactical problem for the queen and the king behind it, forcing a response that cannot preserve the balance. The key idea is not a long attack, but a short forcing sequence where a pinned piece becomes overloaded and the position collapses into a winning simplification.
