King's Gambit Accepted

For White · 23 moves (plies) in the main line

The King's Gambit Accepted (1.e4 e5 2.f4 exf4 3.Bc4) produces a sharp tactical game in this line, as 3...Qh4+ displaces White's king before rapid development creates central and kingside attacking chances.

Themes: pawn-sacrifice, exposed-king, central-initiative, kingside-attack, tactical-play

Key ideas

  • After 4.Kf1, White accepts an uncastled king in exchange for tempi against Black's queen.
  • The sequence 5.d4 and 6.Nc3 builds central pressure while opening lines for White's pieces.
  • White recovers the f4-pawn with 9.Bxf4 and uses 8.Nd5 to place a knight actively.
  • The advance 11.a4 restrains Black's queenside bishop before 12.Nxg5 challenges the kingside pawn cover.

Plans for White

  • Use 5.d4 to contest the center and make Black's bishop move again with 5...Bb6.
  • Develop with 6.Nc3 and 7.Nf3, gaining tempo when Black's queen retreats from f6 to d8.
  • Keep the d5-knight supported and use 9.Bxf4 to restore material while improving the bishop.
  • Calculate 12.Nxg5 carefully, aiming to exploit Black's 10...h6 and 11...g5 pawn commitments.

Plans for Black

  • Black uses 3...Qh4+ to deny normal castling and force 4.Kf1.
  • After 5...Bb6, Black develops with 6...Nc6 and 9...Nf6 while targeting White's exposed king.
  • The queen maneuver 7...Qf6 and 8...Qd8 avoids harassment while keeping central pieces coordinated.
  • Black's 10...h6 and 11...g5 seek to drive away White's f3-knight and gain kingside space.

Mistakes to avoid

  • Treating 4.Kf1 as harmless can leave White's king exposed if development falls behind.
  • Playing 5.d4 without following through with 6.Nc3 can surrender the central initiative.
  • Allowing the f4-pawn to remain undefended after 8.Nd5 wastes the purpose of 9.Bxf4.
  • Launching 12.Nxg5 without calculating Black's king and piece responses can turn an attack into a material loss.
