King's Gambit

What is the King's Gambit?

The King's Gambit starts 1.e4 e5 2.f4. White offers the f-pawn to deflect Black's e-pawn, open the f-file and build a big centre with d4. It was the great battleground of the romantic era and remains the classic gambit: sharp, open and tactical. Today it is rare at the very top, but it is a respected weapon in club play and in faster time controls.

Main ideas and plans

After 1.e4 e5 2.f4 exf4 3.Nf3 your knight stops ...Qh4+ and prepares d4. The classical reply is to hold the extra pawn with ...g5. The Kieseritzky Gambit, 1.e4 e5 2.f4 exf4 3.Nf3 g5 4.h4 g4 5.Ne5, attacks the pawn chain at once and puts your knight in the centre, while the Allgaier Gambit, 1.e4 e5 2.f4 exf4 3.Nf3 g5 4.h4 g4 5.Ng5, sacrifices the knight on f7 for a raw attack. The Fischer Defense, 1.e4 e5 2.f4 exf4 3.Nf3 d6, first takes the e5 square away from your knight and only then supports the pawn with ...g5. Black can also return the pawn with an early ...d5 to free the position, which is one of the most reliable replies.

With the Bishop's Gambit, 1.e4 e5 2.f4 exf4 3.Bc4, you allow the queen check on h4: after 1.e4 e5 2.f4 exf4 3.Bc4 Qh4+ 4.Kf1 you lose the right to castle, but the black queen is exposed and you gain time with Nf3 and d4. Across all lines your plan is the same: build the centre with d4, develop fast, castle or tuck the king away, then regain the f4 pawn with Bxf4 or use the half-open f-file to press against f7. If Black declines with 1.e4 e5 2.f4 Bc5, the bishop stops you from castling short for a while, and the Falkbeer Countergambit, 1.e4 e5 2.f4 d5, strikes back in the centre immediately; both need their own preparation.

Who is it for?

The King's Gambit is for attacking, tactical players who value initiative more than material and are comfortable with an exposed king. It is excellent for learning how to attack, but a well-prepared opponent who knows a solid line such as the ...d5 counterstrike or the Fischer Defense can neutralise it, and mistakes are punished quickly on both sides. Know first why the knight move to f3 is the main line: it prevents ...Qh4+ and covers d4 and e5. Then learn the basic ideas of the Kieseritzky and of Black's ...d5 before you play it in serious games.
