Ruy Lopez: Morphy Defense, Modern Steinitz Defense

Before the first move

The Modern Steinitz Defense is a solid, resilient way to meet the Ruy Lopez. By combining the immediate pressure of the Morphy Defense with the structural stability of a d6 pawn chain, you create a flexible position. White aims to build a powerful center with c3 and d4, while you look to counter-punch and maintain a sturdy defense.

1. e4White

White opens with e4, the most popular choice at all levels. By occupying the center, White prepares for rapid development. While Black has many replies like the Sicilian Defense with c5 or the French Defense with e6, the most direct response is to meet e4 with e5.

1... e5Black · your move

Push your pawn to e5. By mirroring White's move, you stake your own claim in the center and prevent White from easily playing d4. This leads to open games where piece activity and central control are the main themes of the battle.

2. Nf3White

White plays Nf3, the most common second move. It develops a piece and threatens the e5 pawn. Black must now decide how to defend. While rare tries like the Bongcloud with Ke2 or the Center Game with d4 exist for White, Nf3 remains the gold standard for pressure.

2... Nc6Black · your move

Develop your knight to c6. This move defends your e5 pawn and develops a piece toward the center. It is the most robust way to handle the pressure on e5 and prepares for further development of your minor pieces.

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 Game. This puts immediate pressure on the defender of e5. You'll have to choose your defense carefully. While White could play the Italian Game with Bc4 or the Scotch with d4, the Ruy Lopez is considered the most testing.

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. This is the Morphy Defense, the most popular way to challenge the bishop. You force White to make a decision: trade the bishop for your knight or retreat it. This tiny pawn move creates useful luft and prepares future queenside expansion.

4. Ba4White

White plays Ba4, keeping the bishop and the pressure. This is the most common continuation, though the Exchange Variation with Bxc6 is a solid alternative for players who prefer a different pawn structure. By staying on the diagonal, White keeps the tactical possibilities alive.

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

4... d6Black · your move

Push your pawn to d6. This move characterizes the Modern Steinitz Defense. You solidify your e5 pawn and open the diagonal for your light-squared bishop. It is a more flexible approach than the older Steinitz, as you have already forced the white bishop to a4.

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. c3White

White plays c3, preparing a full central expansion. This is a very standard plan. White could also choose to castle immediately or play d4 directly, but c3 is the most patient way to build an advantage. You will need to decide how to meet the upcoming d4 push.

Other paths here: Nc3 (Ruy Lopez: Morphy Defense, Modern Steinitz Defense) · d4 (Spanish: Modern Steinitz, 5.d4) · Bxc6+ (Spanish: Modern Steinitz, Richter Variation) · O-O (Spanish: Modern Steinitz, 5.O-O Bd7)

Where you stand

The position is deeply strategic. White will aim to push d4 and establish a dominant center, while Black often looks to strike back with f5 or develop the light-squared bishop to d7. Both sides have achieved solid development, and the battle will revolve around White's central space versus Black's resilient structure.

• c1-g5 Develop the bishop to pin the knight
• f7-f5 Challenge the center with the f5 break
• d1-e2 Place the queen to support the center
• c8-d7 Develop the bishop to d7 for defense
• e1-g1 Castle kingside to secure the king
