How to play against the Vienna Game

The Vienna Game starts 1.e4 e5 2.Nc3. White develops the queen's knight first, keeping the option of f4 in the style of the King's Gambit, or Bc4 aimed at f7. This guide is about meeting it as Black. The most principled reply is ...Nf6, controlling d5 and e4, while ...Nc6 leads to more classical positions. The character varies from very sharp gambit play to quiet positions, depending on White's third move. The Vienna is a respected and increasingly popular choice for White at club level, and Black needs concrete answers to both f4 and Bc4.

Main ideas and plans

Against the Vienna Gambit, 1.e4 e5 2.Nc3 Nf6 3.f4, the best-known answer is ...d5, hitting the center. After 1.e4 e5 2.Nc3 Nf6 3.f4 d5 4.fxe5 Nxe4 Black's knight is strong; if White plays Nf3 you can choose the solid Breyer Variation with ...Be7 or the active Kaufmann line with ...Bg4, while the Heyde line with Qf3 attacks the knight at once. Against Bc4 you can use the fork trick: 1.e4 e5 2.Nc3 Nf6 3.Bc4 Nxe4 4.Nxe4 d5 regains the piece, while 1.e4 e5 2.Nc3 Nf6 3.Bc4 Nxe4 4.Qh5 Nd6 5.Bb3 leads to sharp play. Here Black chooses between the calmer ...Be7, as in the Alekhine Variation, and the wild Frankenstein-Dracula line, 1.e4 e5 2.Nc3 Nf6 3.Bc4 Nxe4 4.Qh5 Nd6 5.Bb3 Nc6 6.Nb5 g6 7.Qf3 f5 8.Qd5 Qe7 9.Nxc7+ Kd8 10.Nxa8 b6, where Black gives up a rook to trap the knight in the corner.

If you play ...Nc6, then 1.e4 e5 2.Nc3 Nc6 3.f4 exf4 leads to old gambits: the Steinitz Gambit with d4, and the Hamppe-Allgaier, 1.e4 e5 2.Nc3 Nc6 3.f4 exf4 4.Nf3 g5 5.h4 g4 6.Ng5, both risky for both sides. Quieter tries include the Paulsen Variation with g3 and the Mengarini Variation, 1.e4 e5 2.Nc3 Nf6 3.a3, where simple development and ...d5 give Black easy play.

Who is it for?

Preparing against the Vienna is a must for everyone who answers 1.e4 with ...e5, since it has become a common choice at club level. The ...Nf6 and ...d5 approach suits players who like central counterplay; the fork trick suits those who are happy in open, tactical positions. The risk is being caught in a sharp line you have not studied, especially the old gambits after ...Nc6. Know first why Qh5 is met by ...Nd6 after the fork trick: it stops Qxf7 mate and hits the bishop. Also have one solid line ready against f4.
