The King's Gambit arises after 1.e4 e5 2.f4 and falls under ECO code C30. White uses the f-pawn to challenge Black's e5 pawn, despite the fact that f4 is itself undefended and under attack. The strategic goals are twofold: to deflect Black's pawn from d4 so White can occupy it, and to pry open the f-file for the rook after castling. However, this comes at a steep price: advancing the f-pawn before castling severely compromises the kingside and leaves the king vulnerable. The main response is 2...exf4, accepting the gambit and pocketing the pawn, which represents the most challenging test of White's concept. Although the e5 pawn has been removed, White cannot immediately play 3. d4?! because of the threat 3...Qh4+. White therefore typically plays 3. Nf3 first (the King's Knight Gambit), covering h4 before proceeding. In the resulting positions, Black generally tries to retain the extra pawn with ...g5 and exploit the exposed diagonals e1-h4 and a7-g1 through moves like ...Qh4+ and ...Bc5. With 76.9 million Lichess games across all rating levels, it is a well-established opening choice.
