The King's Gambit is a chess opening that begins with the moves 1.e4 e5 2.f4. It aims to sacrifice a pawn to gain rapid development and control of the center. By offering the f4 pawn, White hopes to lure Black into accepting the gambit, leading to an aggressive and tactical game. This opening is popular among players who enjoy sharp, dynamic positions. If Black accepts the gambit, the game can quickly become complex, with both sides needing to navigate potential traps. The King's Gambit has been played by many famous players, including Bobby Fischer and Paul Morphy.
