Do you resign as soon as you lose the queen?

If a game is otherwise even, I have observed that a good majority of opponents will resign as soon as their queen is lost and I totally understand why. I try to stay in the game when I lose the queen as I am still learning and I don't want to squander an opportunity to learn how deal with that level of adversity.

Yeah, if the loss of a queen puts my game in genuine peril, then I will absolutely resign.

Not when I´m playing against my grandchildren.

I don't resign because you can still win if you can take their queen

I probably won't resign there. I'll play on a few more moves and see if I can generate some complications and counterplay, but if no such counterplay is realistic, then I'll probably just resign immediately after hanging the Queen.

I've resigned positions with much less material difference than a Queen (no counterplay), but I've also played on in positions when I was down my even more than a Queen (but had counterplay). According to my All-time stats for rapid, I lose by resignation 26.5% of the time, so I'm not against resigning when it is appropriate to do so, but the majority of the time (at least by my statistics), I end up playing until checkmate.

Surely it depends on your level:

Under 1,000: There's no point resigning. Game is still on and quite often the other player can lose their queen as well. If you're learning the game still, you need to experience all types of games anyway. It's a good way to experience playing with other pieces.

1,000-1,400: You're less likely to win, but can still learn a lot.

1,400+: If the game is lost then there's probably nothing to learn, so nothing to gain. If you were slightly up so are now slightly down it might be different, and positions might matter, so there will be instances where it makes sense to play a queen down, but that might be rarer.

Trying to reach a single answer for all players of all abilities is pointless. Personally I play on as I need to improve a lot, and since my opponents also do I end up winning quite a few games where I'm a queen now. Hopefully in a few years that will stop though as I want to be playing at an higher level then.

And the level of ones opponent. Facing a significantly stronger player queen down isn´t a good idea.

Too many people resign as soon as they are a piece or two down when at the end of the day the opponent still needs to get you into checkmate. If that doesn't look like at anytime soon there is still plenty to play for and it is not bad sportsmanship as some people suggest not to resign. Your opponent still has opportunities to blunder and let you back into the game. Playing to the end allows you to learn to be strong defensively which will benefit you in the long term for future games.

As for sportsmanship it is quite in order to keep playing as long as there´s a realistic hope to draw the game.

Of course.

That isn't true. If you think you can comeback, it's good to continue playing. It isn't bad sportsmanship for wanting to continue trying.

But obviously, at higher rating if you lose your queen, you might want to resign due to your chances of winning without a queen is very slim.

i dont resign unless i have no play left. meaning i can be down a rook or even a queen, but if i still have some counterplay i will play on, and i have won quite a few games because my opponent's got lazy with the conversion and suddenly i got a dangerous attack. (mind you this is the 2100+ level)

so dont resign unless you have no play left in the postiion

There's a lot of truth in this (I'm guessing because I don't play at the higher level) as I've had a few opponents resign after losing a bishop or rook early in the game. I guess that they want a game experience where they put out their best. I get it.

It entirely depends on the position, the time control and everything. I've had games where I've blundered my Queen during an attack, but the attack was so potent that I turned it around really quickly. I've had games where I got my Queen trapped, but was able to get a couple of pieces back for it where it's not so devastating and not so clear where my opponents win is. Also if you're playing bullet, or even blitz and under 2000 rating I see no reason to ever resign. 
However if there's no obvious counterplay, or I'm only getting like a bishop for the queen and my opponent has plenty of time, sometimes I just want out of the game and so will resign to get on with something better. Thankfully these days a full queen blunder is very rare for me, usually if anything else I'm able to get at least 5+ points of material back for a queen should that situation arise.

It would be crazy not to play the game out when you´ve sacrificed your queen... It´s quite another thing when you´ve blundered her away.
