Moreover, the bishop on g7 can also be used defensively to protect the king and prepare for castling.

The move also opens lines for the queen's bishop and queen, which can be aimed at Black's king. Moreover, the move e4 can force Black to make a difficult decision about how to respond to the pawn push, as they do not want to allow White to establish a pawn chain in the center.

Furthermore, the pawn on d6 can potentially support a pawn chain with c7 and b6, which can give Black more space on the board. In sum, d6 is a flexible move that can be used to bolster Black's position and prepare for counter-attacks.
