Ruy Lopez: Morphy Defense

Before the first move

The Ruy Lopez is one of chess's most enduring openings, focusing on long-term pressure and central control. In the Morphy Defense, Black immediately challenges the white bishop, leading to a sophisticated battle of piece maneuvering and pawn structures where both sides fight for every inch of the board.

1. e4White

White opens with e4, the most popular move in chess history. By occupying the center, White immediately prepares for rapid development. While other moves like d4 or c4 are equally valid, e4 leads to some of the most famous and tactical battles in the game.

1... e5Black · your move

Respond by moving your pawn to e5. By mirroring White's move, you prevent them from establishing a dual-pawn center with d4 and ensure you have your own foothold in the middle of the board. This sets the stage for a symmetrical and classical struggle.

Other paths here: f6 (Barnes Defense) · g5 (Borg Defense) · h6 (Carr Defense) · f5 (Duras Gambit)

2. Nf3White

White plays Nf3, developing a piece and attacking the e5-pawn. This is far more common than the Alapin (Ne2) or the Center Game (d4). You must now decide how to defend your central pawn while continuing your own development.

Other paths here: Ke2 (Bongcloud Attack) · d4 (Center Game) · c4 (English Opening: The Whale) · Ne2 (King's Pawn Game: Alapin Opening)

2... Nc6Black · your move

Bring your knight to c6 to defend your e5-pawn. This is the most natural and strongest way to protect your center while developing a piece toward the middle. You are preparing to meet White's next move with a solid foundation.

Other paths here: d5 (Elephant Gambit) · Qe7 (Gunderam Defense) · Bc5 (King's Pawn Game: Busch-Gass Gambit) · f6 (King's Pawn Game: Damiano Defense)

3. Bb5White

White plays Bb5, the signature move of the Spanish Opening. This is considered more testing than the Italian Game (Bc4) or the Scotch (d4). White's bishop creates a lingering threat against your knight, indirectly eyeing the pawn on e5.

Other paths here: Nxe5 (Irish Gambit) · g3 (King's Knight Opening: Konstantinopolsky) · c4 (King's Pawn Game: Dresden Opening) · b4 (King's Pawn Game: Pachman Wing Gambit)

3... a6Black · your move

Push your pawn to a6 to put the question to the bishop. This is the Morphy Defense, the most popular way to handle the Ruy Lopez. You force White to decide whether to capture your knight or retreat the bishop to a4.

Other paths here: Bb4 (Ruy Lopez: Alapin Defense) · g5 (Ruy Lopez: Brentano Gambit) · a5 (Ruy Lopez: Bulgarian Variation) · Nge7 (Ruy Lopez: Cozio Defense)

4. Ba4White

White plays Ba4, opting to keep the bishop rather than entering the Exchange Variation with Bxc6. The bishop still eyes the knight from a distance, and White maintains the flexibility to either retreat further or exert pressure later.

Other paths here: Bxc6 (Ruy Lopez: Exchange Variation) · Bc4 (Spanish: 3...a6 4.Bc4)

4... Nf6Black · your move

Develop your knight to f6. This move attacks the e4-pawn and prepares for kingside castling. It is the most flexible and active continuation, forcing White to address the threat to their own central pawn before continuing their plan.

Other paths here: Nd4 (Ruy Lopez: Bird's Defense Deferred) · Bb4 (Ruy Lopez: Morphy Defense, Alapin's Defense Deferred) · b5 (Ruy Lopez: Morphy Defense, Caro Variation) · Bc5 (Ruy Lopez: Morphy Defense, Classical Defense Deferred)

5. O-OWhite

White castles kingside, the most flexible choice. White could also play d3 to shore up the center or d4 for an immediate break, but castling is the main line. Now you must decide whether to take the e4-pawn or play more solidly.

Other paths here: d3 (Ruy Lopez: Morphy Defense, Anderssen Variation) · Bxc6 (Ruy Lopez: Morphy Defense, Bayreuth Variation) · c3 (Ruy Lopez: Morphy Defense, Jaffe Gambit) · d4 (Ruy Lopez: Morphy Defense, Mackenzie Variation)

Where you stand

The position is a rich crossroads. Black can enter the 'Open' Ruy Lopez by capturing on e4 or the 'Closed' variations by playing Be7. White will typically aim for a slow build-up with c3 and d4, while Black seeks counterplay on the queenside with b5 and active piece placement. Both sides have excellent prospects in the complex struggle ahead.

• f8-e7 Develop the bishop to prepare castling
• f1-e1 Support the center and clear f1
• b7-b5 Kick the bishop and gain space
• c2-d4 Prepare the d4 pawn break
• a4-c2 Preserve the light-squared bishop
