Ruy Lopez Opening
Definition
The Ruy Lopez (also called the Spanish Opening) is a king-pawn opening that arises after the moves
1. e4 e5 2. Nf3 Nc6 3. Bb5.
Named after 16th-century Spanish priest Ruy López de Segura, it is one of the oldest and most deeply analysed openings in chess.
How the Opening Is Used
White places the bishop on b5 to attack the defender of the e5-pawn (the knight on c6). This indirect pressure, combined with rapid development and the possibility of castling kingside, makes the opening a favourite at every level—from beginner to World Championship play.
Strategic Themes
- Central Control: White hopes to eventually play d2–d4, establishing a strong pawn center.
- Piece Activity: Both sides aim to mobilise pieces quickly; Black must decide how to maintain the e5-pawn.
- Pawn Structure: Many Ruy Lopez lines feature the characteristic “Spanish” pawn chain with pawns on d4 (White) vs. d6 and e5 (Black).
- Endgame Potential: Exchange variations often lead to long, maneuvering endgames where small advantages are pressed.
Main Branches at Move 3 …

Historical Significance
The Ruy Lopez has appeared in more World Championship games than any other opening. From Steinitz–Zukertort 1886 to Carlsen–Nepomniachtchi 2021, it remains the battleground for cutting-edge theory.
Interesting Facts
- Ruy López himself considered 3.Bb5 a second-best move; he preferred 3.Bc4 (the Italian).
- The opening’s popularity briefly waned in the early 2000s when Vladimir Kramnik’s Berlin Defense held Kasparov to a draw in their 2000 match, but theory has since revitalised many Ruy Lopez lines.
- AlphaZero’s self-play games frequently employed the Ruy Lopez, adding modern “engine” ideas to centuries-old analysis.
Morphy Defense
Definition
The Morphy Defense is the most common reply to the Ruy Lopez:
1. e4 e5 2. Nf3 Nc6 3. Bb5 a6.
Black immediately questions the white bishop, asking it to decide its intentions. The line is named after the American prodigy Paul Morphy, who used it with great success in the mid-19th century.
Typical Continuations
- 4. Ba4 Nf6 5. O-O Be7 – Main Line (Closed Ruy Lopez)
- 4. Bxc6 dxc6 – Exchange Variation
- 4. Ba4 d6 – Modern Steinitz Defense (see next heading)
Strategic and Practical Ideas
By playing 3…a6, Black:
- Gains the b5 square for the queen-side pawn, often chasing White’s bishop to b3 after …b5.
- Prevents early Bb5xc6 doubling Black’s pawns in many lines (unless White chooses the Exchange).
- Holds back the central break d2–d4 by retaining tension.
Historical Spotlight
In the iconic “Opera Game” (Morphy vs. Duke Karl / Count Isouard, Paris 1858), Morphy used 3…a6 to create dynamic play that culminated in a brilliant mating attack—still a staple of classroom demonstrations.
Famous Modern Example
Magnus Carlsen – Viswanathan Anand, WCh Game 5, Chennai 2013
Carlsen unleashed the positional Exchange Variation (4.Bxc6), steering the game into a long grind and ultimately winning, a key moment in securing his first world title.
Interesting Nuggets
- Although universally called “Morphy Defense,” the move 3…a6 was analysed earlier by Spanish master López himself, who rejected it as inferior!
- The a6–b5 pawn duo often persists into the endgame, granting Black queenside space and minority-attack chances.
Modern Steinitz Defense
Definition
The Modern Steinitz Defense to the Ruy Lopez arises after:
1. e4 e5 2. Nf3 Nc6 3. Bb5 a6 4. Ba4 d6.
It combines Morphy’s 3…a6 with Steinitz’s original 3…d6, hence the term “Modern.”
Contrast with the Old Steinitz
Old Steinitz: 1.e4 e5 2.Nf3 Nc6 3.Bb5 d6 (no …a6).
By inserting …a6 first, Black avoids the pin 4.Bxc6+ in many lines and gains queenside space.
Strategic Features
- Flexible Pawn Chain: …d6 supports …e5 and often prepares …g6 and a fianchetto.
- Slower, Solid Play: Black accepts a cramped position but with few weaknesses—ideal for patient counter-attackers.
- Timed Breaks: Central breaks with …d5 or …f5 must be prepared; otherwise White may seize central dominance.
Main Lines After 4…d6
- 5. c3 Nf6 6. d4 Bd7 (or 6…b5 7.Bc2)
- 5. Bxc6+ bxc6 6. d4 exd4 7. Qxd4 – Sharp Exchange approach
- 5. O-O Be7 6. d4 exd4 7. Nxd4 – Classical line
Illustrative Snippet
Historical Context
Wilhelm Steinitz, the first official World Champion, pioneered 3…d6 in the 1870s. The “modern” flavour (with …a6 first) became popular in the 1980s thanks to players like Anatoly Karpov and Ulf Andersson, who appreciated its solid, maneuvering nature.
Practical Tips
- A well-timed …Na5 or …Bg4 can relieve positional pressure.
- If White over-extends with f2–f4 too early, Black’s …d5 break can equalise instantly.
- Endgames often favour Black because the bishop pair frequently survives, and the a- and c-pawns can become queenside spearheads.
Trivia
- Kasparov tried the Modern Steinitz in his youth but abandoned it, remarking, “Why suffer voluntarily?”—highlighting its reputation for passive positions.
- Computer engines rate the line as fully playable; it is a reliable surprise weapon in modern rapid and blitz.
