Ruy Lopez Opening: Morphy Defense & Wormald Attack
Ruy Lopez Opening
Definition
The Ruy Lopez, also called the Spanish Game, arises after the moves 1.e4 e5 2.Nf3 Nc6 3.Bb5. White’s third move attacks the knight on c6, indirectly pressuring the pawn on e5. First recorded in the 16th century treatise of the Spanish priest Ruy López de Segura, it is one of the oldest and most deeply studied chess openings.
Typical Move Order
- e4 e5
- Nf3 Nc6
- Bb5
After this point Black chooses between several major branches, the most popular being the Morphy Defense (3…a6), the Berlin Defense (3…Nf6), and the Classical Defense (3…Bc5).
Strategic Ideas
- White targets the e5–pawn and aims for long-term queenside pressure by eventually playing
Bxc6followed by c2–c3 and d2–d4. - Black tries to maintain the strong central pawn on e5 and develop smoothly; counterplay often comes from …b5, …d5 breaks, or kingside activity.
- Because piece exchanges are delayed, the Ruy Lopez frequently leads to rich middlegames in which manoeuvring skill is paramount.
Historical Significance
The Ruy Lopez has been a mainstay of master practice for over 400 years. World Champions from Steinitz to Carlsen have relied on it, and entire world-title matches have revolved around its subtleties. Its encyclopaedic body of theory underpins much of modern 1.e4 e5 strategy.
Illustrative Game
Fischer – Spassky, World Championship (Game 6), Reykjavík 1972
Fischer’s brilliant queenside expansion and central break in a Ruy Lopez Exchange Variation remains one of the most celebrated games of the 20th century.
Interesting Facts
- The opening’s ECO codes run from C60 to C99—a larger range than any other single opening family.
- Because of its strategic depth, the Ruy Lopez is often recommended to improving players as a “complete school of chess.”
- In some languages (e.g., German) it is still known simply as “the Spanish.”
Morphy Defense
Definition
The Morphy Defense is the main branch of the Ruy Lopez in which Black replies 3…a6, immediately questioning the bishop on b5. The basic position arises after 1.e4 e5 2.Nf3 Nc6 3.Bb5 a6. Named after the 19th-century American prodigy Paul Morphy, it embodies his preference for rapid development and active piece play.
How It Works
- By forcing White to decide between
Bxc6andBa4, Black clarifies the tension and prepares …b5 to gain space and develop the dark-squared bishop to b7. - After 4.Ba4 (the usual move) Black can choose between:
- 4…Nf6 (the Closed Spanish), leading to rich strategic battles.
- 4…d6 (the Steinitz Variation).
- 4…b5 5.Bb3 Na5 (the Chigorin Variation).
Strategic Themes
- Central Tension – Black often delays …d6 or …d5 to keep options open.
- Queenside Space – The …a6/…b5 pawn duo gives Black a clamp on the queenside and a natural post for the bishop on b7.
- Piece Activity vs. Structure – If White plays
Bxc6, he doubles Black’s pawns but relinquishes the bishop pair; if he retreats, Black gains time.
Historical & Modern Usage
Paul Morphy introduced 3…a6 in the 1850s, sweeping away earlier defensive systems that allowed White to damage Black’s pawn structure without cost. The Morphy Defense is now considered theoretically sound and is the weapon of choice for many elite grandmasters, including Garry Kasparov, Viswanathan Anand, and Magnus Carlsen.
Example Continuation
This tabiya (starting position of a line) illustrates the so-called Closed Spanish, where both sides have completed development and the strategic manoeuvring begins.
Interesting Tidbits
- Paul Morphy not only invented the move but used it to defeat Adolf Anderssen in their famous “Match of the Century” (Paris 1858).
- In the early 20th century, the Morphy Defense was temporarily eclipsed by the Berlin Defense until José Raúl Capablanca and later Alexander Alekhine rehabilitated it.
- The move 3…a6 is so common that club players often refer to it simply as “playing a6,” assuming everyone recognises the context.
Wormald Attack (Ruy Lopez, Morphy Defense)
Definition
The Wormald Attack is a sharp, less common branch of the Morphy Defense characterised by Black’s immediate kingside fianchetto with 4…g6:
- e4 e5
- Nf3 Nc6
- Bb5 a6
- Ba4 g6
Named after the 19th-century English master Henry Wormald, it blends ideas from the Ruy Lopez with the modern fianchetto structures typical of the King’s Indian Defence.
Strategic Concepts
- Dark-Square Control – By placing the bishop on g7, Black exerts long-range pressure on the centre, especially the e5-pawn, and prepares …f7-f5 in some lines.
- Asymmetry – The fianchetto creates an unbalanced pawn structure, offering chances for both sides to play for a win.
- Time Factors – Because Black delays …Nf6 or …d6, White may try to strike quickly with c2-c3 and d2-d4 before Black finishes development.
Typical Continuations
- 5.O-O Bg7 6.c3 Nf6 7.d4 – White builds a classical centre; Black counterattacks with …d6 or …exd4 followed by …O-O.
- 5.d4 exd4 6.O-O Bg7 7.Re1 Nge7 – A more open line where both queens are often exchanged early.
Sample Line
The position is dynamically balanced: Black has the bishop pair and active knights, while White enjoys a healthy pawn structure and central space.
Historical Notes
Henry Wormald (1823-1871) experimented with this early …g6 idea in London club play. Although the variation never reached the popularity of the mainline Closed Spanish, it has sporadically appeared in grandmaster practice. Notable modern exponents include Alexei Shirov and Teimour Radjabov, players renowned for entering sharp, unbalanced positions.

Interesting Facts
- The ECO code for the Wormald Attack is C70.
- Chess engines rate the variation as playable but slightly inferior for Black; nevertheless, its surprise value often compensates at practical time controls.
- Because the bishop is fianchettoed, many thematic sacrifices on f2 or e4 can arise—echoes of the King’s Indian Defence within a 1.e4 e5 framework.
