Modern Defense: Standard Line

Before the first move

The Modern Defense is a hypermodern opening where Black allows White to build an impressive center with the goal of undermining it later. Instead of occupying the middle with pawns immediately, you will use your fianchettoed bishop to exert long-range pressure on the d4-square and White's queenside.

1. e4White

White plays e4, the most popular starting move. By occupying the center immediately, White sets a direct challenge. Black has many ways to respond, from the symmetrical e5 or the solid Caro-Kann to the hypermodern approach we are about to see.

1... g6Black · your move

Push your pawn to g6. This is the hallmark of the Modern Defense. You are preparing to develop your bishop to g7, where it will breathe fire down the long diagonal. You ignore the center for now, waiting to see how White commits their pawns.

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

2. d4White

White plays d4, seizing the full center as Black invited. This is the most principled response. White could also try developing a piece first with Nc3 or Nf3, the latter often leading to Pterodactyl structures, but occupying the center with pawns is the most ambitious test.

Other paths here: Nc3 (Modern) · Bc4 (Modern Defense) · Nf3 (Pterodactyl Defense: Western, Siroccopteryx)

2... Bg7Black · your move

Develop your bishop to g7. This piece is the soul of your position. From g7, it puts indirect pressure on the d4-pawn and prepares for kingside castling. You are now ready to strike at White's center with moves like c5 or d6.

Other paths here: c6 (Modern) · f5 (Modern Defense: Fianchetto Gambit) · Nf6 (Modern Defense: Norwegian Defense) · d6 (Rat Defense: Accelerated Gurgenidze)

3. Nc3White

White plays Nc3, defending e4 and developing naturally. This is the Standard Line. White has several aggressive alternatives here, including the Three Pawns Attack with f4 or the Bishop Attack with Bc4, both of which lead to much more volatile and tactical struggles.

Other paths here: Bc4 (Modern Defense: Bishop Attack) · f4 (Modern Defense: Three Pawns Attack) · Bd2 (Modern Defense: Westermann Gambit) · Bd3 (Modern Defense: Wind Gambit)

Where you stand

The position is a classic clash of styles. White enjoys a space advantage and a solid center, while Black has a flexible setup ready to counterattack. Black will likely play d6 or c6 next to prepare a central break, while White will focus on completing development and deciding whether to castle kingside or queenside.

• g7-d4 Pressure the d4 pawn from afar
• c7-c5 Challenge the center with c5
• c3-d5 Control and potentially occupy d5
• c1-e3 Support the d4 pawn center
• e8-g8 Secure the king via castling
