  1. Before the first move

    The Steinitz Defense in the Three Knights Opening is a solid, hypermodern approach for Black. By preparing to fianchetto the dark-squared bishop, Black aims for long-term control of the center from the wings. White usually seeks to exploit this slightly slower development by striking quickly in the center with d4.

  2. 1. e4White

    White plays e4, the most common opening move in chess. By occupying the center, White prepares for quick development. You will have to choose how to respond; while e5 is the classical answer, other major systems like the Sicilian Defense or the French Defense are also very popular.

  3. 1... e5Black · your move

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

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

  4. 2. Nf3White

    White plays Nf3, putting immediate pressure on your e5 pawn. This is the main line of the King's Knight Opening. While White could try the Alapin with Ne2 or the Center Game with d4, this move is the gold standard for developing with a threat.

    Other paths here: Ke2 (Bongcloud Attack) · d4 (Center Game) · c4 (English Opening: The Whale) · Ne2 (King's Pawn Game: Alapin Opening)

  5. 2... Nc6Black · your move

    Bring your knight to c6. This move defends your e5 pawn and develops a piece toward the center. It is the most principled way to meet White's pressure, setting the stage for many famous openings like the Ruy Lopez or the Italian Game.

    Other paths here: d5 (Elephant Gambit) · Qe7 (Gunderam Defense) · Bc5 (King's Pawn Game: Busch-Gass Gambit) · f6 (King's Pawn Game: Damiano Defense)

  6. 3. Nc3White

    White plays Nc3, entering the Three Knights Opening. This is a very solid choice that focuses on piece development. White could have played Bb5 for a Ruy Lopez or Bc4 for an Italian, but this move keeps the tension and waits to see how you will commit.

    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)

  7. 3... g6Black · your move

    Push your pawn to g6. This is the signature move of the Steinitz Defense. You are preparing to place your bishop on g7, where it will exert powerful pressure along the long diagonal and provide a safe shelter for your king after castling.

    Other paths here: Bb4 (Three Knights Opening) · f5 (Three Knights Opening: Winawer Defense) · Bc5 (Three Knights: 3...Bc5) · d6 (Three Knights: 3...d6)

  8. Where you stand

    The position is strategically rich. White usually continues with d4 to challenge the center immediately, leading to a trade of pawns. Black will fianchetto the bishop to g7 and eventually develop the kingside knight. The battle revolves around whether White's central space advantage outweighs Black's solid structure and long-term pressure from the g7 bishop.

    • d2-d4 Strike in the center with d4
    • f8-g7 Fianchetto the bishop to the long diagonal
    • g8-f6 Develop the knight and prepare to castle
    • e1-g1 Castle kingside to secure the king
