King's Gambit Accepted: Cunningham Defense, Bertin Gambit (variation 2)

This aggressive opening involves sacrificing a pawn to gain rapid development and attacking chances.

In this variation, White offers a pawn sacrifice to Black in exchange for a lead in development and attacking opportunities. By playing Be7 and Bh4+, Black aims to disrupt White's kingside development and create weaknesses in the pawn structure. White responds with Bc4 to maintain pressure on the center and prepare for castling. The move g3 allows White to break the pin on the f3 knight and create an escape square for the king. Black captures the pawn on g3, leading to an exchange of pawns and opening up the h-file for potential attacks. White castles kingside to secure the king's safety and connect the rooks. Black continues with hxg2, creating an open file for the rook and potentially weakening White's kingside pawn structure. This opening leads to a sharp and dynamic position where both sides have chances for an aggressive play.
