Sodium Attack Puzzle (Rated 1281): Win Material — Discovered Attack

This middlegame puzzle shows a classic winning combination built around king safety and a discovered attack. White’s pieces are coordinated to create direct pressure on the black king while also exploiting loose defenders and an overloaded back rank. The key idea is that one forcing move can open a line for a major piece, turning a kingside attack into a decisive material gain. In positions like this, tactical motifs often overlap: discovered attack, sacrifice, and a follow-up rook invasion.
