Catalan Opening Closed Discovered Attack Puzzle (Rated 910): Win Material — Discovered Attack

This middlegame puzzle shows how a forcing tactical idea can outweigh static evaluation. White’s pieces are coordinated around the enemy king, and one active bishop creates a direct threat that also opens a line for the queen. The key motif is a discovered attack: a move that exposes a stronger piece while simultaneously forcing the opponent into a losing response. The result is a clear material win and a decisive advantage, not a speculative attack.
