Mexican Defense Puzzle (Rated 1079): Win Material — Mexican Defense Tactic

This Mexican Defense puzzle is a classic middlegame tactic built around king safety, piece activity, and a forced sequence that wins material. White’s queen and knight coordination looks active, but the position contains a hidden tactical resource for Black because the white king is still exposed and key pieces are overloaded. The key lesson is that a seemingly strong central piece can become a tactical target when it is pinned, attacked, or tied to the king’s defense.
