Mexican Defense Horsefly Gambit Puzzle (Rated 1776): Attack — Kingside Attack
This middlegame puzzle is a classic example of a kingside attack built on king safety, piece activity, and a pinned defender. White’s pieces are ideally placed to exploit the weakened dark squares around the black king, while Black’s back rank and kingside coordination are under pressure. The key idea is to use forcing moves that drag the king into a worse defensive setup and then follow up with a direct tactical strike. The position rewards active play over material counting.
