Overview

Mexican Defense: Horsefly Gambit is a gambit, classified under ECO code A50 within the Flank Openings family. As with all gambits, one side sacrifices material early — usually a pawn — in exchange for development, open lines, or initiative.

The Flank Openings group covers flank openings — systems that delay the central pawn break and instead develop pieces and pawns on the wings.

Play reaches this position via 1. d4 Nf6 2. c4 Nc6 3. d5 Ne5 4. f4, after 7 plies of opening development.

It is a variation of Mexican Defense, which itself descends from the root opening Queen's Pawn Game.
