The King's Gambit: 1.e4 e5 2.f4... 3.Nf3 arises after 1.e4 e5 2.f4 exf4 3.Nf3 and falls under ECO code C34. The knight development serves the dual purpose of controlling h4, which prevents Black from exploiting the opened diagonal with Qh4+, and preparing White's plan of d4 followed by Bxf4 to recover the gambitted pawn. Black naturally wants to hold onto the extra material on f4 if possible. Among the many available responses, the three most important are 3...g5 (the Classical Defence), 3...d6 (the Fischer Defence), and 3...d5 (the Modern Defence). A pawn is the most effective way to shield f4, and the g-pawn is the only one available for the task. Piece defenses fall short: 3...Bd6? blocks Black's own d-pawn and invites e5 with tempo, while 3...Qf6? runs into 4. e5 and the queen cannot maintain its defense (4...Qf5? 5. d4 d5 6. Bd3). The Classical Variation with 3...g5 is the main line, simultaneously guarding f4 and threatening the aggressive ...g4 advance to dislodge the f3-knight. Black can afford to weaken the kingside because the f4-pawn secures ample space on that flank, meaning any kingside expansion by White runs directly into Black's own advancing pawns.
