Vienna Game: Anderssen Defense
Vienna Game – Anderssen Defense
Definition
The Vienna Game: Anderssen Defense is the line 1. e4 e5 2. Nc3 Bc5. Black sidesteps the more common 2…Nf6 and instead develops the queen’s-bishop to an active post on c5, eyeing the vulnerable f2-square and exerting early pressure on the centre. The opening’s ECO classification is C26.
How it Arises
After 1.e4 e5 2.Nc3, White keeps the option of f2–f4 (the Vienna Gambit) or a quick d2–d4. Black’s 2…Bc5 answers both ideas by:
- aiming directly at f2, discouraging premature kingside expansion,
- developing a piece without blocking the c-pawn, and
- retaining flexibility regarding …Nf6, …Nc6, or …d6.
Strategic Themes
Plans for White
- d2–d4 break: often prepared by 3.Nf3, it can fork Black’s pieces after …Nc6.
- Na4 Idea: Exchange or chase the c5-bishop to win the bishop pair.
- Vienna Gambit: 3.f4!? keeps the opening true to its romantic roots.
Plans for Black
- Pressure on f2: Tactical shots like …Bxf2+ or …Qh4 appear if White is careless.
- Rapid Development: …Nc6, …Nf6, and kingside castling aim for a healthy, classical set-up.
- Central Counter: Depending on White’s choice, Black can choose …d6 (solid), …d5 (dynamic), or …c6 (Swiss-style structure).
Historical Significance
The variation is named after Adolf Anderssen (1818-1879), the legendary German tactician famed for the “Immortal” and “Evergreen” games. Anderssen adopted the early …Bc5 against the nascent Vienna system in several informal games, and the line soon carried his name. Though fashionable in the late 19th century, it gradually ceded popularity to the sounder 2…Nf6, yet it has never been refuted and still scores respectably at club level.
Illustrative Games

Adolf Anderssen – Louis Paulsen, Leipzig 1877
A classic illustration of White’s central thrust; Anderssen’s pawns overwhelm Black after timely piece sacrifices.

A modern top-level skirmish: Carlsen transforms the position into a favorable endgame, demonstrating the line’s strategic, not merely tactical, potential.
Tactical Motifs to Remember
- d4 Fork: 3.Nf3 Nc6 4.Nxe5 Nxe5 5.d4! hits both the bishop on c5 and the knight on e5.
- Bxf2+ Sacrifice: If White delays Nf3 and overextends, …Bxf2+ Kxf2 Qf6+ can win material or force a perpetual.
- Pin Multiplex: …Qf6 simultaneously eyes f2 and the knight on c3 after Bc4.
Theoretical Status
Engine evaluations hover around +0.20 in White’s favour—nothing dramatic but enough that most professionals prefer alternative defences. For practical play, however, the Anderssen Defense remains:
- Sound – no direct refutation exists;
- Flexible – Black can transpose to familiar Italian-style structures;
- Surprising – many opponents expect 2…Nf6 and are forced to think from move two.
Interesting Facts
- The same ECO code (C26) also covers the Ponziani Opening, so two very different openings share the same database slot.
- Contrary to its aggressive namesake, the Anderssen Defense is strategically solid and rarely involves speculative sacrifices from Black.
- In some older British sources the move 2…Bc5 is dubbed the “Bishop’s Vienna.”
Practical Tips
- For White: Memorise the d4 fork and the Na4 manoeuvre; both yield enduring structural gains.
- For Black: Versus 3.f4!? consider 3…d6 4.Nf3 Nc6, steering into calm waters without conceding central space.
- Excellent choice for rapid or blitz—sound yet off the beaten grand-master path.
