Mexican Defense Horsefly Gambit Puzzle (Rated 1174): Win Material — Fork Tactic
This middlegame puzzle is a classic example of a winning combination built around a knight fork and a forcing check. White’s active knight jumps into the king zone, creating immediate threats against the enemy queen and king while also exposing loose pieces. The key idea is that tactical pressure can override material imbalance when the opponent’s king is vulnerable and coordination is poor. After the forcing sequence, White wins material and simplifies into a clearly better ending.
