You made a mistake and lost your queen.
Your opponent can make a mistake too.
As long as you have hope, play on.
Here is a game where Reshevsky lost his queen.
He played on and lost, but he put up resistance.

Do you resign when you blunder and lose your queen?

It happened to me again a few days ago, and for the first time I continued the game... And I won, because the opponent made a couple of colossal blunders in turn.
Actually, when I lose so much material ( even less ), I immediately resign. Not because I think there is no chance to turn the game around ( the probability is small, but it's nowhere near zero), but simply because at that point I know that I could only win if the opponent makes a clamorous mistake, and it makes me lose interest in continuing.
In any case, if one continues to play he has good reasons to do so.



Once a queen is lost if the leading player exchanges all his piece even he will end up with the queen advantage in the end game. . . .

If you lose your queen without any compensation (e.g., you didn't get any material or positional advantage in return) and the position is clearly lost, it might be practical to resign.

I often continue for a few moves...sometimes if you blunder it encourages your opponent to blunder as well.Sometimes people get a bit laid back in won positions and fall asleep .
That said i will resign if it's obvious he's still awake .

Never!
Id say 50 percent of the times I lose my queen I still dont lose the game. Im 1200 rapid and theres a chance the opponent will flag or stalemate or disconnect. Not to mention blunders and misses which happen to both players multible times in almost all my games.
Some of the time it emboldens your opponent and they relie on their queen to win the game making it an easier target to win back. Especially in bullet and blitz. .
Also there are many mating patterns that don't envolve a queen. Harder to see but more likely to work. Not to mention the ever popular back rank checkmate
Besides winners aren't known for quitting. And quitters aren't known for winning.
But number one reason I don't quit is because I might capture their queen and get to see them rage quit which is hilarious.

I generally play on. I've blundered my queen enough times and still won and I'm a total low rated wonder.


If you are a beginner or low rated it's generally best to continue.In the above game i would continue for a couple of moves then resign ...sometimes an opponent will relax after winning your Queen then blunder themselves.
It's a bit psychological but when you blunder often that encourages your opponent to blunder as well.
When you lose your queen, you are down -9 and it's pretty much impossible to comeback and win. Unlike sports such as basketball or Football, if you get down, you still have a chance to comeback and win but in chess, once you get down, it's nearly impossible to comeback
