A King's Gambit with the knight already developed and the king safer
Also known as Vienna f4, Vienna Game Gambit.
The main line
1.e4 e5 2.Nc3 Nf6 3.f4 d5 4.fxe5 Nxe4 5.Nf3 Be7 6.d4 O-O 7.Bd3 f5 8.exf6 Bxf6 9.O-O Nc6
Strategic ideas
- Play f4 with Nc3 already in — the extra defender of e4 fixes the King's Gambit's main flaw
- Blast open the f-file and put a rook behind it
- Punish the greedy …exf4 with e5 and d4, building a huge centre with tempo
- Take on e5 to gain space and drive the black knight to squares it doesn't want
- Attack down the half-open f-file toward f7 while Black is still untangling
Key themes
- Attack — The f-file opens straight onto f7 and White's pieces flow into the attack behind it
- Dynamic — A pawn is often offered and the compensation is speed — the position never sits still
- Open Files — The half-open f-file is the highway; every white plan runs down it
Typical plans
This is the King's Gambit's more sensible sibling. In the King's Gambit, f4 comes when e4 is undefended and Black's …Qh4+ ideas are real; here Nc3 already covers e4, so White gets the same attacking f-file with far fewer holes. Black's best is the counter-strike 3…d5 rather than grabbing on f4. White gains space with fxe5, builds with d4, and points everything at f7. It's a proper attacking weapon at club level and it's been played by strong grandmasters too.
Move by move
- e4 — White claims the centre.
- e5 — Black meets it symmetrically.
- Nc3 — White develops the knight, defending e4 — which is exactly what makes the coming f4 sound.
- Nf6 — Black develops and eyes e4.
- f4 — White plays the gambit. This is a King's Gambit with Nc3 already in, so …Qh4+ never comes with tempo and e4 doesn't hang.
- d5 — Black hits back in the centre. Grabbing with …exf4 lets White play e5 and build a huge centre with tempo — this is the tested reply.
- fxe5 — White takes, gaining space and kicking the f6-knight forward.
- Nxe4 — Black takes on e4 rather than retreating, restoring material equality with an active knight.
- Nf3 — White develops and prepares to challenge the centre.
- Be7 — Black develops and prepares to castle out of the danger zone.
- d4 — White builds the big pawn centre and takes away the c5 and e5 squares.
- O-O — Black castles into safety before White's f-file rook arrives.
- Bd3 — White develops, aiming at h7 and challenging the e4-knight from behind.
- f5 — Black props up the knight with the pawn. It's the only way to keep it on e4 — but it also creates a target.
- exf6 — White takes en passant, ripping the black kingside open and killing the knight's support.
- Bxf6 — Black recaptures with the bishop, keeping the structure as tidy as possible.
- O-O — White castles, connecting the rooks and putting one on the half-open f-file — pointing straight at f7.
- Nc6 — Black develops the last knight, hitting d4. The position is roughly balanced but every white piece has a natural attacking square, which is what the gambit paid for.
Where the line leads
White's plans
- Get a rook to f1 and play against f7 — the half-open file is the whole point
- Build the centre with d4 and c4 while Black's e4-knight has no permanent support
- Look for Nxe4 and Bxf5 shots; Black's kingside is full of loose squares
Black's plans
- Meet f4 with …d5, not …exf4 — counterattacking in the centre is the tested answer
- Hold the e4-knight with …f5 and …Bf5/…Nc6, and don't let it get chased away for free
- Castle quickly and trade off White's attackers before the f-file rook does damage
