Ruy Lopez: Open, Bernstein Variation
Ruy Lopez: Open Variation
Definition
The Open Variation of the Ruy Lopez arises after the moves:
1. e4 e5 2. Nf3 Nc6 3. Bb5 a6 4. Ba4 Nf6 5. O-O Nxe4
Black immediately captures the e4–pawn, accepting a temporary material lead in exchange for central tension and dynamic piece play. The ECO codes C80–C83 are devoted to this system.
How It Is Used in Play
- Dynamic counter-punch: By grabbing the pawn, Black invites complications and relies on rapid piece development to neutralize White’s initiative.
- Central pawn majority: After the typical sequence 6.d4 b5 7.Bb3 d5, Black hopes to maintain or recapture a healthy central pawn duo (…c7–c5 often follows).
- Imbalance early on: The position quickly becomes open and tactical, in stark contrast to the more strategic Closed Ruy Lopez.
Main Move-Order and Branches
- 1.e4 e5 2.Nf3 Nc6 3.Bb5 a6 4.Ba4 Nf6 5.O-O Nxe4
- 6.d4 b5 7.Bb3 d5
- Critical continuations:
- 8.Nxe5 (classical main line)
- 8.dxe5 (leading to the so-called Motzko lines)
- 8.a4 (fighting the b-pawn immediately)
- 8.Re1 (Janowski Variation)
- 8…Be6 9.c3 introduces the Bernstein Variation, covered in the next section.
Strategic Themes
- Piece activity over material: Black’s extra pawn is hard to keep. Surviving the opening complications usually returns material equality but yields lively piece play.
- e4-square tug-of-war: Both sides contest the key central square, often deciding whether Black’s knight can stay or must retreat.
- c-file pressure: Black often plays …c5, opening the c-file against White’s queenside.
Historical Significance
The Open Ruy Lopez was a favorite of attacking legends such as Frank Marshall and Efim Geller, and it remains a fighting weapon at top level. Its theoretical foundations were laid in the late 19th century, but modern engines have added fresh resources for both sides.
Illustrative Game
Marshall–Capablanca, New York 1918, featured the Open Variation and birthed many classic motifs, including the “Marshall counter-attack” ideas that later inspired his famous gambit in the Closed Ruy Lopez.
Interesting Facts
- Because theory remained stagnant for decades, the Open Ruy Lopez earned a “surprise-weapon” reputation—strong yet less common than the Closed lines.
- Modern elite players such as Fabiano Caruana and Levon Aronian reintroduced it with computer support, reviving its popularity in the 2010s.
Bernstein Variation (Open Ruy Lopez)
Definition
The Bernstein Variation is a specific branch of the Open Ruy Lopez characterized by the move …Be7 on move 9 instead of the more forcing …Bc5:
1.e4 e5 2.Nf3 Nc6 3.Bb5 a6 4.Ba4 Nf6 5.O-O Nxe4 6.d4 b5 7.Bb3 d5 8.dxe5 Be6 9.c3 Be7
The line is named after the Russian master and theoretician Ossip Bernstein, who championed it in the early 20th century.
Core Ideas
- Flexible development: By placing the bishop on e7, Black keeps options open for the light-squared bishop and delays early commitments on the c-file.
- Solid kingside: …Be7 fits neatly into …O-O, reducing tactical shots on f7 or g7 while still supporting central action with …f6 or …c5 later.
- e5 outpost for White: White often stations a knight or pawn on e5; Black aims to undermine it with …f6.
Typical Continuation
A main line runs:
- 10.Nd4 Qd7 (reinforcing the e6-bishop)
- 11.Nxe6 fxe6
- 12.Nd2 O-O
- 13.Nxe4 dxe4
The resulting structure features opposite-side pawn majorities and semi-open f- and d-files for active piece play.
Strategic Significance
- Compared to the “Classical” 9…Bc5, the Bernstein line is slightly more solid but gives White extra tempi to organize play. In return, Black enjoys a safer king and robust central pawns.
- Prized by players who want the spirit of the Open Ruy Lopez without memorizing razor-sharp forcing lines.
Historical & Modern Usage
Ossip Bernstein used the line with success in international tournaments before World War I. Later, Anatoly Karpov revitalized it during the 1970s, appreciating its positional nuances. In the computer era, engines confirm its soundness, and it occasionally appears in elite practice (e.g., Carlsen–Nakamura, London 2012 rapid).

Interesting Tidbits
- The quiet 9…Be7 move once puzzled analysts; Bernstein preferred clear development over immediately challenging White on the queenside.
- Because it is slightly rarer, many Ruy Lopez specialists spend less time on this branch, making it an attractive surprise weapon even today.
