  1. Before the first move

    The Averbakh System of the Modern Defense is a bold strategic battleground. White establishes a massive, classical pawn center with d4, c4, and e4 to clamp down on the board, while Black prepares to strike back from the flanks. You will learn how to balance White's space advantage against Black's flexible, hypermodern counter-attacking potential.

  2. 1. d4White

    White plays d4, the most common alternative to e4. By occupying the center, White invites you to choose your defensive structure. You can enter the Queen's Gambit with d5, or choose more flexible Indian setups.

  3. 1... g6Black · your move

    Push your pawn to g6. You are preparing to fianchetto your bishop to g7, where it will exert long-range pressure across the longest diagonal. This flexible move avoids immediate central tension.

    Other paths here: Na6 (Australian Defense) · g5 (Borg Defense: Borg Gambit) · b6 (English Defense) · e5 (Englund Gambit)

  4. 2. c4White

    White plays c4, expanding in the center and preparing a Queen's Indian or King's Indian style structure. White could also choose e4 or Nf3, but c4 is the most ambitious way to fight for space.

    Other paths here: Nf3 (Queen's Pawn: Modern) · h4 (Modern Defense: Lizard Defense, Pirc-Diemer Gambit) · e4 (Pterodactyl Defense: Eastern, Benoni) · Nc3 (Pterodactyl Defense: Eastern, Benoni Pterodactyl)

  5. 2... Bg7Black · your move

    Develop your bishop to g7. This is the centerpiece of your strategy, placing your bishop on a powerful diagonal that will eventually pressure White's central pawns and the queenside.

  6. 3. Nc3White

    White plays Nc3, a standard developing move that reinforces d5 and prepares to take more space. White often chooses between this and the immediate e4, both of which lead to very sharp play.

    Other paths here: e4 (Queen's Pawn: Modern)

  7. 3... d6Black · your move

    Push your pawn to d6. This solidifies your position, controls e5, and prepares to develop your other pieces. It prevents White from simply pushing their pawns further into your territory.

    Other paths here: c5 (Queen's Pawn: Modern)

  8. 4. e4White

    White plays e4, completing the massive three-pawn center. This is the defining position of the Averbakh System. You must now find a way to challenge this wall, likely with Nf6 or e5, before White finishes development.

  9. Where you stand

    The battle lines are drawn. White possesses a space advantage and a formidable center, while Black has a solid, flexible position ready to spring into action. White will look to develop the kingside and castle, while Black must decide whether to strike at the center with e5 or c5 to create counterplay and undermine White's broad pawn front.

    • g8-f6 Develop the knight to challenge the center
    • g1-f3 Develop the knight to prepare castling
    • e7-e5 Strike at the d4 pawn immediately
    • f1-e2 Develop the bishop to castle kingside
