Spanish: Morphy Defence

Before the first move

The Morphy Defence is the most popular way to meet the Ruy Lopez. By playing a6, Black immediately questions the white bishop on b5, forcing White to decide whether to capture on c6 or retreat. This flexible approach allows Black to maintain a solid center while preparing to expand on the queenside.

1. e4White

White begins with e4, the most popular starting move. It immediately fights for the center and prepares for rapid development. While White could try d4 or c4, e4 leads to some of the most storied openings in chess history, challenging you to respond accurately to maintain the balance.

1... e5Black · your move

Reply by moving your pawn to e5. This mirrors White's move, claiming an equal share of the center and preventing White from easily pushing a second pawn to d4. It is the most principled way to enter a symmetrical King's Pawn game.

2. Nf3White

White plays Nf3, the most natural developing move, attacking your e5-pawn. You must now decide how to defend it. While White occasionally tries the Center Game with d4 or the Alapin with Ne2, the knight move to f3 is by far the most testing and common continuation.

2... Nc6Black · your move

Bring your knight to c6 to defend your e5-pawn. This is the most efficient way to protect your center while developing a piece. You are preparing for the upcoming struggle over the central squares and keeping your options open.

3. Bb5White

White plays Bb5, the signature move of the Ruy Lopez. White isn't just attacking the knight; they are fighting for long-term central control. You could also see the Italian Game with Bc4 or the Scotch Game with d4, but the Spanish pressure on c6 is particularly nagging.

3... a6Black · your move

Push your pawn to a6 to kick the bishop. This is the Morphy Defence. You are forcing White to make a decision: will they trade their valuable light-squared bishop for your knight, or will they retreat and allow you to expand later with b5?

4. Ba4White

White opts for Ba4, the main line, choosing to keep the bishop rather than playing the Exchange Variation with Bxc6. The bishop still eyes your queenside, but it has been nudged back. You must now continue your development while staying alert to the pressure on e5.

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

4... Nf6Black · your move

Develop your knight to f6. You are attacking White's e4-pawn and preparing to castle. This move is the most solid continuation, focusing on king safety and central pressure before deciding on a specific pawn structure with b5 or d6.

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)

Where you stand

The position is rich with strategic possibilities. White will likely castle and then look to play c3 and d4 to build a strong center. Black should prepare to castle and may use the b5 expansion to fully kick the white bishop, eventually developing the light-squared bishop to b7 or e7. The game will revolve around White's central pressure and Black's queenside counterplay.

• e1-g1 Castle to secure the king
• f8-e7 Develop bishop and prepare castling
• c2-c3 Prepare the d4 central strike
• b7-b5 Expand on the queenside
• a4-b3 Reposition bishop to a safer diagonal
