Mexican Defense Puzzle (Rated 1091): Win with a Fork — Opening Tactics

This puzzle comes from the Mexican Defense and shows a classic opening tactic where king safety and piece coordination matter more than raw material. White’s queen activity creates a forcing sequence that exploits the exposed black king and the loose bishop on the queenside. In the opening, a single check can change everything when it wins tempo, disrupts development, and leaves a key piece hanging. The idea is to use forcing moves to gain a decisive advantage before the opponent can coordinate.
