user18013: In many of my games, I'm having problems with developing my queen.
I'm aware of basic principles such as not moving the queen too early, or developing it after the minor pieces and so on. Yet, I wonder what else comes after these principles. In general, I'm looking for some practical advice on developing and using my queen better. I'm ~1900 in rapid and ~1700 in blitz on lichess if that matters.

user13012: Because the Queen is so versatile, it is hard to give general rules, but you might try asking the question, which of my other pieces do I want her to cooperate with? She might combine with one of your Bishops to attack squares of that color, or with Rook(s) to control an open file. Queen and Knight can be deadly together because neither is restricted to one color.
Queens are great at shepherding passed Pawns. Paradoxically, you might ask whether there is a task to be done that none of the others can achieve? In all cases, the key is to think about her in relation to your other pieces.
