Ruy Lopez: Morphy Defense & Modern Steinitz

Ruy Lopez: Morphy Defense

Definition

The Morphy Defense is the most popular reply by Black to the Ruy Lopez opening. It arises after the moves 1. e4 e5 2. Nf3 Nc6 3. Bb5 a6. By playing …a6, Black immediately asks the white bishop on b5 to decide its future—capture the knight on c6 or retreat—thereby clarifying the central tension and claiming space on the queenside.

How It Is Used in Chess

Players adopt the Morphy Defense to:

  • Prevent White from inflicting structural damage by Bxc6 at an inconvenient moment.
  • Gain a tempo: if 4. Ba4, the bishop has moved twice while Black has made only one pawn move.
  • Create flexible transpositional possibilities into nearly every major Ruy Lopez system (Closed, Open, Berlin, Archangelsk, etc.).

Strategic Significance

  • Space vs. Solidity: White enjoys central space after d2–d4 and c2–c3, but Black’s sturdy pawn on e5 and prospect of …b5–…Bb7 give long-term counterplay.
  • Piece Activity: Black’s light-squared bishop often emerges via …Bb7 or …Bc5; the knight on f6 attacks e4; meanwhile White’s bishop pair and central pawn majority fuel attacking chances on the kingside.
  • Endgame Themes: If White eventually exchanges on c6 doubling Black’s pawns, the resulting pawn structure frequently grants Black the bishop pair and half-open b-file for counterplay.

Historical Notes

Named after the 19th-century American genius Paul Morphy, who championed 3…a6 with great success. Although Morphy’s contemporaries preferred the more passive 3…d6 (Old Steinitz), his dynamic approach laid the foundation for modern Ruy Lopez theory.

Illustrative Example

The celebrated sixth game of the 1972 World Championship match shows the power of White’s pressure—even when Black equalizes in the Morphy Defense:


Fischer eventually converted a classic positional squeeze against Spassky (Reykjavík 1972, Game 6).

Typical Continuations

  1. Closed Ruy Lopez: 4. Ba4 Nf6 5. O-O Be7 6. Re1 b5 7. Bb3 d6 (main battleground of top-level play).
  2. Open Variation: 4. Ba4 Nf6 5. O-O Nxe4.
  3. Exchange Variation: 4. Bxc6 dxc6 5. O-O.

Interesting Facts & Anecdotes

  • Garry Kasparov employed the Morphy Defense in five of his six wins with Black during the 1990 World Championship match against Anatoly Karpov.
  • In many databases, simply entering “Ruy Lopez” defaults to Morphy Defense lines because the move 3…a6 has eclipsed all alternatives in modern practice.
  • Paul Morphy’s original treatment often included an early …f5, a forerunner of the modern Marshall Attack.

Modern Steinitz Defense (Ruy Lopez)

Definition

The Modern Steinitz Defense arises after 1. e4 e5 2. Nf3 Nc6 3. Bb5 a6 4. Ba4 d6. It combines Steinitz’s original idea of reinforcing the e5-pawn with the more flexible Morphy move …a6, hence the adjective “modern.” ECO code: C71.

Purpose and Usage

  • Reinforce the Center: …d6 solidifies e5, preventing the immediate d4 break.
  • Retain Structural Options: Black can later choose between …Nf6, …g6, …Be7, or even …f5, adapting to White’s setup.
  • Avoid Theoretical Minefields: By delaying …Nf6, Black sidesteps the heavily analyzed Open Ruy Lopez (5…Nxe4).

Strategic Themes

  1. Closed Nature: The pawn chain e5–d6 often leads to maneuvering battles reminiscent of King’s Indian structures.
  2. Delayed Development: Black sometimes leaves the g8-knight on its home square to prepare …f5 or …g6–…Bg7, complicating White’s central plans.
  3. Piece Re-routing: The c6-knight may retreat to b8–d7, freeing the c-pawn for …c6 & …d5 breaks.

Historical Context

Wilhelm Steinitz advocated 3…d6 as early as the 1860s, claiming that a strong pawn center outweighed rapid development. Modern masters realized that starting with 3…a6 first reduces early tactical vulnerabilities, hence the “Modern” prefix. The line gained prominence in the 1980s through players like Ljubomir Ljubojević and Nigel Short.

Illustrative Example


The diagram (after 10…Re8) shows Black’s solid yet flexible setup. Both sides maneuver before committing pawn breaks.

Critical Variations

  • Siesta Variation: 4…d6 5. c3 f5!? — a sharp line championed by Portisch and Topalov.
  • Pert Variation: 4…d6 5. c3 g6 adopting a fianchetto structure.
  • Classical Line: 4…d6 5. c3 Bd7 leading to slow maneuvering.

Notable Games

  • Short vs. Kasparov, Linares 1993 – Kasparov unleashed the Siesta 5…f5 and achieved dynamic equality.
  • Anand vs. Topalov, Corus 2006 – Topalov demonstrated the power of …g6–…Bg7 setups, holding comfortably with Black.

Interesting Facts

  • Though once considered passive, engines now rate the Modern Steinitz as entirely sound; many top Grandmasters employ it as an occasional surprise weapon.
  • The name Siesta supposedly comes from the Hotel Siesta in Budapest, where the 1928 tournament featured 5…f5 for the first time.
  • Because it blends 3…a6 and 3…d6 ideas, some databases label the line Hybrid Defense, but “Modern Steinitz” remains the standard term.
