King's Gambit: Definition and Overview
King’s Gambit
Definition
The King’s Gambit is an aggressive chess opening that begins with the moves 1. e4 e5 2. f4. White immediately offers the f-pawn as a sacrifice in order to deflect Black’s central e-pawn, seize rapid control of the center, and open attacking lines toward the enemy king. The opening belongs to the family of Open Games (1. e4 e5) and is one of the oldest and most romantic lines in chess history.
Basic Move Order & Main Branches
After 1. e4 e5 2. f4 the critical position is reached:
- 2…exf4 – The accepted line (King’s Gambit Accepted, KGA). Black grabs the pawn and tests White’s compensation.
- 2…d5 – The Falkbeer Counter-Gambit, striking back in the center.
- 2…Bc5 – The Classical or KGA, Bishop’s Gambit Declined.
- 2…exf4 3. Nf3 g5 – Leads to the famous KGA, Kieseritzky (Main) Variation.
Strategic Ideas for White
- Rapid Development: Play Nf3, Bc4, 0-0 to mobilize pieces before Black consolidates the extra pawn.
- Open Lines: The half-open f-file and diagonals a2–g8 or c4–f7 are ideal highways for mating attacks.
- Center Control: After …exf4, White often strikes back with d4 or d3 to rebuild the pawn center.
- King Safety by Activity: Counter-intuitively, attacking is how White keeps the king safe; passivity usually proves fatal.
Strategic Ideas for Black
- Return the Pawn at the Right Moment: Timely …d5 or …g5–g4 can give Black a lead in development while neutralizing White’s attack.
- Piece Placement: Knights often head to f6 and e7; the dark-squared bishop may go to g7 after …g7–g6.
- Keep the Kings Safe: Black frequently castles queenside or delays castling to avoid the opened f-file.
Historical Significance
The King’s Gambit was the gold standard
of attacking play in the
19th century. Masters like Adolf Anderssen, Paul Morphy, and
Rudolf Spielmann used it to create brilliancies that shaped romantic chess
culture. Wilhelm Steinitz’s positional school later dampened its
popularity, but the opening never vanished.
Famous Games & Model Attacks
- Anderssen vs. Kieseritzky, London 1851 – The Immortal Game: After sacrificing both rooks and the queen, Anderssen mated with minor pieces. A timeless illustration of piece activity over material.
- Spassky vs. Fischer, Mar del Plata 1960 – The future world champions slugged it out in the Kieseritzky line; Spassky won a celebrated attacking duel.
- Kasparov vs. Short, NBC simul 2001 – Kasparov revived the gambit in a televised exhibition, winning in 23 moves.
Modern Evaluation
Computer engines give Black a slight but stable edge (≈ +0.3 to +0.6), yet practical results remain double-edged, especially in rapid and blitz. Surprise value and forcing play make it a viable weapon below the elite super-GM level.

Practical Tips
- If playing White, know at least one forced drawing line—the gambit can burn you if Black is well prepared.
- As Black, decide early between holding the pawn (…g5) or returning it (…d5). Indecision often leads to disaster.
- Study endgames arising from the Bishop’s Gambit (3. Bc4) where opposite-colored bishops give White lasting chances.
