Professor Archer says: I sometimes call the Ruy Lopez the "university" of chess openings. If the Italian Game is your introductory course, the Ruy Lopez is your graduate studies. It teaches patience, long-term planning, and the art of building a position move by move over twenty or thirty turns. Understanding the Ruy Lopez means understanding strategic chess at its deepest level.
What Is the Ruy Lopez?
The Ruy Lopez arises after 1.e4 e5 2.Nf3 Nc6 3.Bb5. Named after the 16th-century Spanish priest Ruy López de Segura, it is one of the most deeply analyzed openings in chess history and has been played in more world championship matches than any other system.
The bishop on b5 does not attack anything directly in the way that the Italian Game's Bc4 targets f7. Instead, it exerts subtle, indirect pressure. The bishop targets the c6 knight, which is the primary defender of the e5 pawn. By threatening to capture this knight, White creates long-term tension in the center.
The brilliance of the Ruy Lopez is that White rarely executes the threat immediately. The pin (or quasi-pin) on the knight is more valuable as a persistent nuisance than as an exchange. White maintains the bishop on b5 (or retreats it to a4 after ...a6), keeping the pressure alive and shaping Black's development for many moves to come.
Key Moves and Ideas
The most common continuation is the Morphy Defense: 3...a6 4.Ba4 Nf6 5.O-O Be7 6.Re1. This sequence illustrates the Ruy Lopez's character perfectly. White develops methodically, castles for safety, and maintains central tension without committing to any drastic action.
White's long-term plan revolves around preparing d4. The typical setup involves c3 (supporting d4 and giving the bishop a retreat on c2), d4 (the key central break), and then Nbd2 or Nc3 depending on the structure. When White achieves d4 successfully, the position opens and White's pieces become very active.
Black's counterplay typically involves ...b5, ...Bb7 (controlling the long diagonal), and eventually ...d5 or ...c5 to challenge the center. The Ruy Lopez is a chess conversation: White presses, Black responds, and the resulting middlegame positions are among the richest in all of opening theory.

Common Mistakes
- Capturing on c6 too early as White - After 3.Bb5, beginners often rush to play Bxc6. While the Exchange Variation (Bxc6) is playable, it gives Black the bishop pair and a solid center. The tension of the bishop on b5 or a4 is usually more valuable than the immediate exchange.
- Ignoring the center as Black - Black sometimes gets distracted by queenside expansion (...a6, ...b5) and forgets to contest the center. The ...d5 or ...d6 followed by ...d5 break is essential for Black's counterplay. Without central action, White's space advantage becomes overwhelming.
- Pushing d4 prematurely as White - The d4 advance is White's key break, but timing is everything. Playing d4 before completing development or without c3 support can backfire. Prepare carefully with c3, Re1, and piece development before committing to the central advance.
Famous Games
Ruy López de Segura himself analyzed this opening in his 1561 treatise, making it one of the first openings to receive serious theoretical treatment. His work laid the foundation for five centuries of development.
José Raúl Capablanca, the third World Champion, was renowned for his precise handling of Ruy Lopez positions. His endgame technique in the resulting structures was virtually unbeatable, demonstrating how the opening's subtle advantages can be converted deep into the game.
Magnus Carlsen has revived the Ruy Lopez in modern chess, employing it frequently in world championship matches. His ability to squeeze advantages from seemingly equal Ruy Lopez positions shows why this opening remains the ultimate test of positional understanding.
Frequently Asked Questions

The Ruy Lopez is best suited for intermediate players who already understand basic opening principles. Its ideas are subtle and long-term, requiring patience and positional understanding that beginners may find challenging. Starting with the Italian Game and progressing to the Ruy Lopez is a natural learning path.
What are the main ideas of the Ruy Lopez?
White uses the bishop on b5 to pressure the c6 knight, which indirectly targets the e5 pawn. The long-term plan involves preparing d4, building a strong center, and exploiting the slight space advantage. Black counters with ...b5, ...Bb7, and eventual ...d5 or ...c5 breaks.
What is the best response to the Ruy Lopez?

Professor Archer says: Do not be intimidated by the Ruy Lopez's reputation for depth. You do not need to memorise twenty moves of theory. Understand the core ideas: pressure on e5 through the c6 knight, building a strong center with d4, and preparing a slow expansion. The rest will come with experience and practice at the board.
Quick Quiz
What does White's bishop on b5 primarily pressure in the Ruy Lopez?
- The f7 pawn directly - The f7 pawn is the target in the Italian Game (3.Bc4), not the Ruy Lopez. The bishop on b5 points at c6, not f7.
- The c6 knight, indirectly pressuring the e5 pawn (Correct) - Correct. The bishop targets the c6 knight, which is the main defender of the e5 pawn. This indirect pressure on the center shapes Black's entire opening strategy and is the defining idea of the Ruy Lopez.
- The a6 square to prevent queenside expansion - Black actually plays ...a6 willingly in the Morphy Defense, and it is the most popular response. The bishop does not prevent queenside expansion at all.
- The black king through a direct pin - There is no direct pin on the king from b5. The bishop targets the knight on c6, and the pressure is indirect, flowing through the knight to the e5 pawn.
