Developing Queen, Especially in e4 e5 games


Other than not developing the Queen too early, there is no "general rule".
For example, in the Vienna Game, Frankenstein-Dracula Variation (1.e4 e5 2.Nc3 Nf6 3.Bc4 Nxe4), the White Queen goes 4.Qh5, forcing 4...Nd6 or else Black gets mated.
In the Ruy Lopez, main lines (1.e4 e5 2.Nf3 Nc6 3.Bb5 a6 4.Ba4 Nf6 5.O-O Be7 6.Re1 b5 7.Bb3 d6 8.c3 O-O 9.h3), the White Queen usually stays on d1 for quite some time. Where it goes later on depends on Black's future reactions.
As for the Sicilian, in many lines there is the "English Attack" where it goes to d2. In many Najdorf lines, like 6.Bg5, it goes to f3.
So you can't base the ideas on the placement of any one piece. It's all about piece coordination, having a plan, finding and attacking weaknesses, etc. For example, in many lines of the Sicilian, it's about Black attacking the e4 pawn, not about what square he puts his Queen on.

Well it has to move to connect your rooks
Even then that depends on the opening. Some openings the Rooks are rarely connected.
It's often a long time, if ever, before White's Rooks are connected in the main line Ruy, and one case where they are almost NEVER connected is in the Classical King's Indian. Typically Black's a8-Rook does almost nothing, and often he is willing to scarifice it on the basis that White wastes a lot of time doing it. The other Rook is usually lifted to f7, Bishop goes back to f8, and the Rook goes either to g7 or h7 while the other Rook remains on a8. The Bishop usually sits on c8, and Black must make certain that it is NEVER traded off, even for a White Rook. It is typically needed in order to sacrifice itself on h3, and if White is stupid enough to advance a pawn to h3, all the better!
So even connecting Rooks is not a generality that you can validly use!
Chess is about specifics, not generalities!
So I have been studying chess for a little over a year now, and have just realized that I, in all of my games, have never been sure of where or when or why develop my queen. If anyone has any general rules that would be really helpful. (I mostly play e4-e5 games and the Sicilian, If that matters )
