The King's Gambit

Sacrifice now, attack later.

The King's Gambit is one of the oldest and most romantic openings in chess. After 1.e4 e5, White immediately offers a pawn with 2.f4 — not for material gain, but to open the f-file, accelerate development, and launch a kingside attack.

Once the defining opening of 19th-century chess, the King's Gambit fell from fashion as defensive technique improved. Yet it never disappeared. Players from Spassky to Nakamura have used it as a surprise weapon. At club level it remains one of the most dangerous openings White can play.

Key ideas

  • 2.f4 offers a pawn to open the f-file for the rook and accelerate White's kingside attack
  • If Black accepts (2...exf4), White develops rapidly and attacks before Black can consolidate
  • Nf3 is the key move — developing with tempo while preparing to support the center
  • White's plan is direct: develop fast, castle kingside, use the open f-file to attack
  • The Falkbeer Counter-Gambit (2...d5) allows Black to fight back in the center immediately
