Bishop's Opening: Berlin, Vienna Hybrid, Hromádka Variation
Bishop’s Opening
Definition
The Bishop’s Opening is the position arising after the moves 1. e4 e5 2. Bc4. White develops the king’s-bishop immediately to the aggressive c4–square instead of the more common 2.Nf3. The opening is catalogued in ECO codes C23–C24.
Typical Move-Order
- e4 e5
- Bc4 …
Black has several main replies, the most popular being 2…Nf6 (the Berlin Defence to the Bishop’s Opening) and 2…Bc5 (Classical Defence). Other choices include 2…c6, 2…d6, and gambit attempts such as 2…f5?!.
Strategic Themes
- Rapid Piece Play: White puts immediate pressure on f7 and keeps the f-pawn free for an eventual f2–f4 (King’s Gambit style).
- Flexible Centre: Because the queen’s-knight is still on b1, White can decide later between d2–d3, c2–c3 & d2–d4, or even f2–f4.
- Early Tactics: Motifs such as Bxf7+ (the “Fried Liver–style” sacrifice) or Ng5 in some transpositions can appear quickly.
Historical Significance
The opening was fashionable in the 19th century—Adolf Anderssen, Paul Morphy, and Howard Staunton all used it—before falling out of top-level favour. In modern chess it serves as a flexible surprise weapon and as a gateway to several other openings (Italian, Vienna, King’s Gambit Deferred, etc.).
Illustrative Miniature
The famous “Schulder–Löwenthal” pattern shows how quickly the Bishop’s Opening can produce a mating attack if Black is careless.
Interesting Fact
Because the bishop leaves the e2–square, White can castle queenside in some lines after an eventual c2–c3 & d2–d4, creating positions that feel more like a reversed Sicilian than a typical open game.
Berlin Defence (in the Bishop’s Opening)
Definition
The term “Berlin Defence” most often evokes the Ruy Lopez (3…Nf6), but the same city lends its name to 2…Nf6 against the Bishop’s Opening:
- e4 e5
- Bc4 Nf6
Black hits the e4-pawn at once and aims for speedy development.
Key Ideas for Black
- Counter-attack e4 instead of guarding f7.
- Keep the position fluid; after …Nf6-e4 Black can equalise materially, while …c6 & …d5 stakes out space in the centre.
- Possibility of transposing into quiet Italian-type structures or sharper gambits such as the “Berlin Defence Gambit” 3.Bxf7+?!.
Typical Continuations
After 3.d3 (the most common reply), Black chooses between:
- 3…c6 (setting up …d5),
- 3…Nc6 (entering the Vienna Hybrid—see below), or
- 3…d5 4.exd5 Nxd5 with a Scotch-like centre.
Historical Note
Early references date back to the Berlin Chess Club in the mid-1800s. Although less celebrated than the “Berlin Wall” in the Ruy Lopez, it shares the same reputation for solidity.
Example Snippet
Black has equalised in development, and the symmetrical pawn structure offers few weaknesses.
Vienna Hybrid
Definition
The Vienna Hybrid is a crossover line in which White plays the Bishop’s Opening (Bc4) first and only later develops the queen’s-knight to c3, borrowing a key idea from the Vienna Game. The most common sequence is:
- e4 e5
- Bc4 Nf6 (Berlin Defence)
- d3 Nc6
- Nc3
Why “Hybrid”?
In the pure Vienna Game (1.e4 e5 2.Nc3), the bishop is still on f1. Here the early Bc4 gives White extra pressure on f7, while Nc3 later supports d2–d4 or f2–f4. Thus the structure fuses Bishop’s Opening and Vienna ideas.
Plans for Each Side
- White: Castle kingside, play f2–f4 (sometimes as a pawn sac), or expand with g2–g4. The central break d3–d4 is also thematic.
- Black: Counter by …Bb4, …Na5, or the solid …Be7 & …d6 set-up. Rapid …d5 can punish slow play.
Modern Practice
The line is seen mostly in rapid and blitz, where its flexibility—and the fact that it dodges mountains of Ruy Lopez theory—makes it attractive. Grandmasters such as Nigel Short and Baadur Jobava have experimented with it.
Hromádka Variation
Definition
The Hromádka Variation is a branch of the Bishop’s Opening: Berlin Defence, Vienna Hybrid. Named after Czech master Karel Hromádka (1887-1956), it arises after:
- e4 e5
- Bc4 Nf6
- d3 Nc6
- Nc3 …
Most reference books attach Hromádka’s name to the position after 4.Nc3, although some specify further moves such as 4…Bb4 5.Nge2.
Main Strategic Features
- Triangular Centre: pawns on c2–d3–e4 give White a sturdy scaffold that can later advance to d4 or f4.
- Delayed Knight Development: Because White’s g1-knight is still at home, Ng1–e2–g3 can bolster an eventual f2–f4 pawn storm.
- Piece Tension: Black often chooses between …Bb4 pinning the knight, …Na5 chasing the bishop, or the calm …Bc5 followed by normal development.
Sample Position

Classic Game
Hromádka – Hromádka (analysis game), Prague 1923:
The creator demonstrated how quickly central tension can explode; note his characteristic maneuver Nge2–g3-f5 that became a thematic blueprint for later practitioners.
Why Play It Today?
- Surprise Value: Very little concrete theory exists beyond move 10, allowing a well-prepared player to take opponents out of their comfort zone.
- Balanced Risk: White keeps the position sound (no pawn gambits are required) yet retains attacking chances with f2–f4 or g2–g4.
- Historical Charm: Using a line pioneered by a Czech master of the 1920s gives a nod to chess heritage.
Trivia
Karel Hromádka was also a renowned problem composer and once beat Emanuel Lasker in a simultaneous exhibition. His opening ideas, though never mainstream, influenced several hypermodern thinkers of his era.
