History

Almost every 19th-century master played it, and Anderssen's 'Immortal Game' is a King's Gambit. It is rarer today but remains an effective surprise weapon.

White's plan

  • f4 deflects the e5 pawn so White can build a big centre with d4.
  • The opened f-file is used by the rook after castling to attack f7.
  • Rapid development (Nf3, Bc4, Nc3) compensates for the pawn.

Black's plan

  • Taking and defending the pawn with ...g5 is the classical way.
  • Returning the pawn with ...d5 for quick development is a modern, solid reaction.
  • Declining is also possible: 2...Bc5 or the Falkbeer 2...d5.
