Spanish: Brentano Variation

Before the first move

The Spanish Game, or Ruy Lopez, is a classic battle for the center. In the Brentano Variation, Black adopts an extremely aggressive stance by launching the g-pawn early. This creates sharp tactical complications where White must react precisely to exploit the holes in Black's kingside while Black seeks immediate counterplay.

1. e4White · your move

Push your pawn to e4. This move claims the center and opens diagonal lines for your queen and light-squared bishop. It is the most popular way to start, leading to open games where piece activity is paramount.

1... e5Black

Black replies with e5, meeting White's ambition head-on. This classic response sets the stage for the Ruy Lopez or the Italian Game. Alternatives like the Caro-Kann or the Scandinavian Defense would lead to very different pawn structures and strategic goals.

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

2. Nf3White · your move

Develop your knight to f3. This is the most natural and strongest continuation, as it immediately attacks the e5 pawn and prepares for kingside castling. You are forcing Black to defend while bringing a piece into the action.

2... Nc6Black

Black defends with Nc6, the most common response. By protecting the e5 pawn, Black maintains the central balance. Other options like the Petroff Defense with Nf6 or the sharp Elephant Gambit with d5 exist, but they allow White different types of advantages.

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 · your move

Slide your bishop to b5 to pin or pressure the knight on c6. This is the Ruy Lopez, one of the most respected openings in chess. You are indirectly attacking the e5 pawn by threatening to remove its defender.

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

Black plays a6, the Morphy Defense. This is the most popular reply, forcing the bishop to declare its intentions. Black could also try the solid Berlin Defense with Nf6 or the Schliemann Gambit with f5, but a6 remains the most flexible choice.

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 · your move

Retreat your bishop to a4. You maintain the pressure on the c6 knight while keeping your bishop on an active diagonal. This avoids the immediate trade and keeps the tension high in the center.

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

4... g5Black

Black shocks the board with g5, the Brentano Variation. Instead of standard moves like Nf6 or Bc5, Black seeks immediate complications. This move aims to kick the knight from f3 and seize the initiative, though it creates significant weaknesses in Black's own camp.

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 now highly volatile. White should look to strike in the center with d4 to exploit Black's loosened kingside, while Black will try to use the g4 thrust to displace White's defenders. White's lead in development is crucial, but Black's space on the kingside can become dangerous if White plays too passively.

• d2-d4 Strike the center to exploit the g5 weakness
• f3-h4 Relocate the knight if attacked by g4
• g5-g4 Push further to harass the f3 knight
• c6-d4 Contest the center if White pushes d4
