    Takes central space with a protected pawn and frees the queen’s bishop.

    Idea: Build a stable center that supports a broad positional setup.

    Advances the c-pawn to gain queenside space and control new squares.

    Idea: Create useful wing space while keeping the central structure flexible.

  4. 2…g6

    Idea: Create useful wing space while keeping the central structure flexible.

  5. 3.Nf3

    Idea: Improve piece coordination and clear the back rank for castling and the rooks.

  6. 3…d5

    Advances to d5 to claim central space and control nearby key squares.

    Idea: Give the pieces room to develop behind a durable central foothold.
