Owen Defense Pin Puzzle (Rated 940): Exploit a Pin — Winning Combination

This middlegame puzzle is built around a powerful pin that turns a seemingly defended position into a tactical win. White’s bishop pressure creates a direct threat against the black king’s shelter while also attacking key pieces along the same line. The result is a forcing sequence where Black’s coordination breaks down and White wins material with a decisive advantage. It’s a classic example of how king safety and piece activity can outweigh raw material in classical chess.
