Taking Out One’s Queen

I bring out my queen early once in a while if the circumstances are right (maybe about 5% of games). It can do a lot of damage quick. But the risk of losing it is pretty high.
I obviously try to be very careful with my moves, and I always make sure it has at least two safe exits or fallback positions if things go wrong. It generally works out, but sucks when it doesn't. Like I say, I only do it when I feel a bit risky and see a good opportunity early in the game.

I don´t think, that trapping the queen is the great danger. It´s more about getting your own queen shooed across the board while your opponent get´s a quick developement.
Bringing the queen out early is NOT a mistake in and of itself.
The problem with pulling it out is putting it somewhere that is useful AND cannot be attacked. If your opponent can develop a piece and attack your queen in one move, that costs you a developing move and time and position -- things that are hard to measure at first, but trust me, they hurt your chances.
I really like the modern center counter / scandanavian openings, and those can have the queen out on move 3 or 4! Most of the queen early attemps, esp by the bots like nelson, however are bad openings not because the queen was out early but because the attacks can be countered and the counters improve the defender while the queen player isn't developing and has no strategy that works against someone who is playing well. After 5 or 6 moves the queen player is way behind and losing, and doesn't understand why or what is happening.
The advice is given to beginners because beginners who do this will end up in one of 2 places: they will lose the queen, or they will lose the game due to lack of development, loss of tempos, and lack of a backup plan if the queen can't do any damage. If you like the idea, though, you can study some of the openings that 'do it right' where at the worst you are more or less equal with your opponent, and at best, well positioned for tactics.
I can't recommend nelson enough as a beginning sparring partner. He will flatten you until you figure out how to deal with it, and then you start winning, and then you start destroying him in just a few moves ... and then when someone tries this junk on you, you will win, and beyond that, you will understand a bit more about openings in general (namely, some key weak spots that can be attacked, a bishop can do most of what a queen does in the wandering queen opening...)
I noticed a good deal of the bots on here utilize their queen pretty quickly into the game, and it works fairly well when I play them. I understand that me getting beaten by said bots is more due to my lack of chess skills than taking out your queen early being a superior strategy— but I was always told that taking out your queen early on was a big mistake. Now I’m wondering if it’s possible for it not to be.
