Ruy Lopez Opening Morphy Defense Bayreuth Variation
Ruy Lopez Opening
Definition
The Ruy Lopez, also called the “Spanish Game,” arises after the moves 1. e4 e5 2. Nf3 Nc6 3. Bb5. Named after the 16th-century Spanish cleric Ruy López de Segura, it is one of the oldest and most deeply analyzed chess openings, renowned for leading to rich middlegame positions that balance tactical skirmishes with profound strategic plans.
Typical Move Order & Early Branches
After 3.Bb5 Black has several major options, each sending play into a different “family” of variations:
- 3…a6 – the Morphy Defense (by far the most popular choice).
- 3…Nf6 – the Berlin Defense, famous from the Kasparov–Kramnik World Championship (2000).
- 3…d6 – the Steinitz Defense, a solid but cramped line.
- 3…f5 – the Schliemann (Gambit) Defense, an aggressive counter-attack.
Strategic Themes
- Central tension: The Ruy Lopez is fundamentally about the struggle over the e- and d-files. White pressures the e5-pawn, while Black fights for …d5.
- Bishop vs. knight imbalance: By pinning the c6-knight, White hints at the long-term value of the light-squared bishop. In many lines Black spends time either driving it away (…a6, …b5) or exchanging it.
- Long‐term plans: Castling kingside, maneuvering the queenside knight to g3, f5 or d5 (via b1-d2-f1-g3), and preparing c3 & d4 are typical White ideas. Black, in turn, often plays …b5, …Bb7, …Re8, …Bf8, and …d5 or …c5 breaks.
Historical Significance
The Ruy Lopez has featured in virtually every World Championship match since Steinitz–Zukertort (1886). Game 6 of Fischer – Spassky, Reykjavík 1972, where Fischer employed the “closed” variation and produced an immortal strategic masterpiece, remains a textbook demonstration of its potential.

Interesting Facts
- Because top-level engines evaluate the starting position of the Ruy Lopez as approximately equal and yet highly unbalanced, it remains a cornerstone of elite repertoire—offering winning chances without undue risk.
- Grandmaster Frank Marshall delayed revealing his famous 8…d5 gambit (the Marshall Attack) for eight years, “saving it” for his 1918 game against World Champion José Raúl Capablanca.
Morphy Defense (Ruy Lopez)
Definition
The Morphy Defense is the line 1. e4 e5 2. Nf3 Nc6 3. Bb5 a6. With the immediate thrust …a6, Black questions the bishop and prevents Bb5-c6 doubled-pawn structures, entering the modern main highway of the Ruy Lopez.
Key Ideas & Plans
- Expel the bishop: 4.Ba4 is virtually forced. Black’s queenside pawns gain space after …b5.
- Flexible development: Black often combines …Nf6, …Be7, and …O-O, keeping options open for either …d5 (Open Variations) or …d6 (Closed Variations).
- Tempo Economics: By chasing the bishop, Black “spends” a tempo on …a6 but argues the bishop’s retreat also costs White a move, maintaining dynamic balance.
Main Branches After 3…a6
- 4.Ba4 Nf6 5.O-O – leads to the Open (5…Nxe4) or Closed (5…Be7) systems.
- 4.Ba4 d6 – transposes to the Steinitz Variation.
- 4.Bxc6 – the Exchange Variation, popularized by Fischer.
Historical & Modern Usage
Paul Morphy did not actually invent the move …a6, but his brilliant handling of the resulting positions in the mid-19th century persuaded future generations of its soundness. Today it is practically compulsory: at Super-GM level, declining 3…a6 is rare outside of specific preparation.
Sample Line
Anecdotes & Trivia
- GM Bent Larsen once quipped, “If you don’t like 3…a6, you don’t like chess,” underscoring the move’s central place in opening theory.
- During the 2018 World Championship, Fabiano Caruana employed the Morphy Defense in multiple games, relying on ultra-deep engine preparation to hold Magnus Carlsen to draws.
Bayreuth Variation (Ruy Lopez, Morphy Defense)
Definition
The Bayreuth Variation is a quiet sideline beginning 1. e4 e5 2. Nf3 Nc6 3. Bb5 a6 4. Ba4 Nf6 5. d3. Rather than the more theoretical 5.O-O or 5.Bxc6, White solidifies the e4-pawn with d3, postponing central pawn clashes.
Origin of the Name
The line was analyzed and played at the 1889 Bayreuth tournament in Germany, hence the title. Emanuel Lasker used it there en route to winning the event, giving the variation early publicity.
Strategic Characteristics
- Controlled center: By supporting e4 with d3, White maintains a light-square grip and avoids early exchanges.
- Maneuvering battle: Typical piece routes include Nb1-d2-f1-g3 for White and …Bf8-e7, …O-O, …Re8, …Bf8 → f8/h6 for Black.
- Delayed tension: Because pawns remain on e4 & e5, both sides have time for long plans. The game often resembles a “slow burn” positional encounter, ideal for players who favor structure over concrete forcing lines.
Theoretical Status
Objectively the Bayreuth yields equal chances, but its lower theoretical burden makes it attractive as a surprise weapon. Modern grandmasters such as Sergei Tiviakov and Levon Aronian have sprinkled it into their repertoires to avoid the jungle of Marshall-Attack analysis.
Typical Continuations
- 5…Be7 6.O-O d6 7.Re1 O-O 8.c3 – a solid tabiya.
- 5…b5 6.Bb3 Bc5 7.c3 d6 8.O-O – Black chooses an early …Bc5 aiming at …d5 breaks.
Model Miniature
Interesting Nuggets
- The move 5.d3 neatly sidesteps the dreaded Marshall Gambit (which only appears when White has already played c3 & d4). Many club players adopt the Bayreuth expressly for this reason.
- Because piece play is paramount, engines often fluctuate in their evaluation of the ensuing positions, making human understanding particularly valuable.
- Some databases still classify 5.d3 lines under ECO code C70, the same broad code used for many “miscellaneous” Morphy-Defense sub-variations.
