For example, let us look at the following chess diagram. It is white's turn. Until now, black queen and rook were safe, but white plays d6! White pawn makes an active attack on the black rook but also opens a2–g8 diagonal, which allows white bishop to attack the black queen (and the bishop is protected by the knight).
So, is there a separate name for this maneuver? I don't think it is a fork.
