Ruy Lopez: Fianchetto Defense

Before the first move

The Ruy Lopez is one of the oldest and most respected openings in chess. By playing the Fianchetto Defense, you aim to place your bishop on g7 to exert long-term pressure on the center while keeping your structure solid. It is a sophisticated choice favored by world champion Vasily Smyslov to avoid more tactical mainlines.

1. e4White

White starts with e4, the most popular and ambitious opening choice. By controlling the d5 and f5 squares, White sets the stage for an open game. While many replies exist, most games proceed with a direct challenge to this central control.

1... e5Black · your move

Respond by pushing your pawn to e5. By mirroring White's move, you stake your own claim in the center and prevent White from easily advancing a second pawn to d4. This leads to the Open Games, where both sides fight for central space.

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

2. Nf3White

White plays Nf3, developing a piece and creating the first point of tension by attacking e5. You will see this move in the vast majority of games, though the Center Game with d4 or the King's Gambit with f4 are aggressive alternatives you might encounter.

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 efficient way to protect your center while developing a minor piece toward the middle. You are now ready to meet White's pressure on the next move.

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, entering the Spanish Game. This is a deep opening where White tries to prove that the pressure on c6 is worth the bishop's excursion. You'll often see the Italian Game with Bc4 or the Scotch Game with d4 as major alternatives here.

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... g6Black · your move

Push your pawn to g6. This move signals the Fianchetto Defense, preparing to tuck your bishop away on g7. From that diagonal, it will defend your king and strike across the center, offering a flexible and sturdy alternative to the more common a6 lines.

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

Where you stand

The game now transitions into a strategic battle. White will likely castle and push for d4 to open the center, while Black will finish the fianchetto and look to challenge White's central dominance. Both sides must be careful; White has more space, but Black's position is incredibly resilient and ready for a counter-strike.

• f8-g7 Fianchetto the bishop to control the long diagonal.
• e1-g1 Castle kingside to secure the king.
• c2-c3 Prepare the d4 pawn break to challenge the center.
• d7-d6 Solidify the e5 pawn and open the light-squared bishop.
