King's Gambit

The King's Gambit (1.e4 e5 2.f4) is the most romantic opening in chess. White offers a pawn on move two to rip open the f-file, accelerate development, and launch an attack against Black's king. It dominated 19th-century play - Morphy and Anderssen built brilliancies on it - but fell out of fashion at the top level once defensive technique caught up. It still wins games at every other level.

Main line: Kieseritzky Gambit

After 2...exf4 3.Nf3 (preventing ...Qh4+ from causing mayhem) 3...g5 (Black tries to hold the extra pawn) 4.h4! g4 5.Ne5, White reaches the Kieseritzky setup. The knight on e5 is monstrous: it eyes f7, g6 and d7, and Black's kingside pawn structure is shredded. White will follow up with Bc4, d4 and O-O, aiming everything at f7.

Variations

King's Gambit Declined (2...Bc5)

Black refuses the pawn and develops normally. The bishop on c5 stops White from playing f-file attacks easily, because castling kingside now drops the bishop into pins. White typically plays 3.Nf3 d6 4.Nc3 Nf6 5.Bc4 and tries to make the f-pawn count in the long run. Less sharp than the Accepted - but theoretically Black is doing fine here.

Falkbeer Counter-Gambit (2...d5)

The most principled counter. Black ignores the e-pawn and strikes in the centre. After 3.exd5 e4! Black has thrown back a gambit pawn of their own and got a strong central pawn that cramps White. Modern theory suggests 3...c6!? as an even tougher try. Many King's Gambit players hate facing the Falkbeer - the romantic attack never materialises.

Muzio Gambit (4.Bc4 g4 5.O-O!?)

Pure 19th-century insanity. After Black kicks the knight with ...g4, White castles anyway and lets the knight die: 5...gxf3 6.Qxf3. White has sacrificed a whole knight for an open f-file, a developed queen, and a target on f7. Sound? Probably not against a computer. Fun? Always. If you want to feel like Anderssen in the Immortal Game, this is your line.

Common traps

Don't allow ...Qh4+: in the King's Gambit Accepted, if White ever forgets to play Nf3 quickly and Black gets ...Qh4+ in, the queen sits on h4 forever, eyeing e1 and f2. White's whole kingside structure becomes a liability. This is why 3.Nf3 is essentially forced after 2...exf4.

Watch the long diagonal: with f4 played, the a7-g1 diagonal points right at White's king. Black often gets in ...Bc5 or ...Qb6 hitting f2 or g1. Castling kingside without first dealing with these threats can lose on the spot.

Typical plans for White

The plan is always the same: develop fast, get the king to safety (usually short castling once the f-file opens for the rook), and aim every piece at f7 or h7. The bishop comes to c4, the queen often swings to e1 or h4 via h5, and the rooks file along the f-line. If Black survives the first 15 moves, White is usually a pawn down with no compensation. So either win in the opening or accept a worse endgame - that's the gambit's deal.
