Vienna Game
Initial Moves: 1.e4 e5 2.Nc3
Strategic Summary & Main Idea
The Vienna Game swaps the king's knight for the queen's knight on move two: 2.Nc3 guards e4, prepares f4 and keeps open the choice between a gambit and a quiet fianchetto. The measurement shows a balanced opening. The position after 2.Nc3 is +0.12, half the +0.23 of 2.Nf3, and the Vienna Gambit, the reason for playing it, measures −0.21 after 3...d5. The two gambits after ...Nc6, the Hamppe-Allgaier and the Pierce, measure −1.53 and −1.40. The Vienna buys little-studied positions and pays for them in advantage.
The pawn structure this opening produces
The Vienna starts with the symmetrical 1.e4 e5 structure, and the difference lies in what the c3 knight allows. With the knight in front of the c-pawn, White gives up c3 and a supported d4, and the centre comes to depend on the f4 advance. When it comes as a gambit and Black answers ...d5, the centre opens at once: after fxe5 Nxe4, White has a pawn on e5 gaining space and Black has a centralised knight that cannot easily be driven away. It is a King's Gambit structure with one extra developing move for each side, and what decides is who uses the f-file first. In the Mieses Variation, with g3, the structure closes: the bishop goes to g2, White does not push the f-pawn early and, after ...d5 and exchanges on d5, the doubled pawn on c3 is the price of a solid centre. When White chooses Bc4 and d3, the position becomes an Italian without c3, with the d-pawn on d3 and slow manoeuvring play. In every version, d5 is the square that matters: White sends the knight there and Black wants a pawn on it.
Typical Plans for White
- Play f4 on move three and open the f-file before Black completes castling
- In the Mieses Variation, fianchetto with g3 and Bg2 and keep the game slow, with d5 as the target
- Against 2...Nc6 3.Bc4 Bc5, play 4.Qg4 and force 4...Kf8 — the position measures only +0.11
- Do not take on g7 with the queen against 4...Nf6: the line ends at −6.89
- Avoid the Hamppe-Allgaier and Pierce gambits: both measure below −1.40
Typical Plans for Black
- Against 3.f4, answer 3...d5 and centralise the knight on e4: the position favours Black
- Do not accept with 3...exf4, which allows 4.e5 and leaves the knight without a square: +0.68
- In the Frankenstein-Dracula, give up the rook for initiative only with the exact sequence up to 10...b6
- Against 4.Qg4, play 4...Kf8; the queen on f6 loses to Nd5
- Against Bc4, develop with ...Bc5 and ...d6 and keep the symmetry until the centre is defined

+0.13 | An Italian without c3, manoeuvring and with no immediate break |

+0.11 | Black loses castling, but White's queen came out too early to exploit it |
| Hamppe-Allgaier Gambit | 1.e4 e5 2.Nc3 Nc6 3.f4 exf4 4.Nf3 g5 5.h4 g4 6.Ng5 |
−1.53 | The knight is given on g5 for an attack on f7; the lowest evaluation in the entry |
| Pierce Gambit (5.d4) | 1.e4 e5 2.Nc3 Nc6 3.f4 exf4 4.Nf3 g5 5.d4 |
−1.40 | The d-pawn replaces the piece sacrifice, and measures almost the same |

Frequently asked questions
Is the Vienna Gambit good for White?
Not by the measurement. After 3.f4 d5 4.fxe5 Nxe4 5.Nf3 Be7, the position is −0.21, with Black slightly better. The gambit pays when Black accepts with 3...exf4 (+0.68) or pins with 5...Bg4 (+0.08 after 6.Qe2), not against the central reply.
Does the Hamppe-Allgaier work?
No. After 3.f4 exf4 4.Nf3 g5 5.h4 g4 6.Ng5, the position is −1.53; with 6...h6 7.Nxf7 Kxf7, −1.38. The knight given on f7 buys an exposed Black king, but not enough to make up for the piece. The Pierce Gambit, with 5.d4 instead of the sacrifice, measures −1.40.
What to do against the Frankenstein-Dracula?
As White, taking the rook is safe: after 10.Nxa8 b6 the position is +0.61. The knight on a8 is trapped and Black gains initiative, but the extra rook weighs more. Anyone who does not want that chaos can avoid the line with 4.Nxe4 instead of 4.Qh5.
Common Mistakes & Where Most Amateurs Go Wrong
- 01 Defending g7 with 4...Qf6? against 4.Qg4. After 5.Nd5 Qxf2+ 6.Kd1 Kf8 7.Nh3 Qd4 8.d3, Black's queen is out of play and the d5 knight threatens c7: +3.10, against +0.11 for 4...Kf8. The line:
1.e4 e5 2.Nc3 Nc6 3.Bc4 Bc5 4.Qg4 Qf6 5.Nd5 Qxf2+ 6.Kd1 Kf8 7.Nh3 Qd4 8.d3+3.10 - 02 Taking on g7 with the queen against 4...Nf6. After 5.Qxg7 Rg8 6.Qh6, White's queen has left the defence of f2, and 6...Bxf2+ opens the White king with material gain: −6.89. The line:
1.e4 e5 2.Nc3 Nc6 3.Bc4 Bc5 4.Qg4 Nf6 5.Qxg7 Rg8 6.Qh6−6.89
