Why do some people resign after their queen has been captured?

Some players who resign prefer to use their time to start new games or run other errands than spending time trying to save losing positions.
Some others have the mentality of that having no queen when their opponents have one is as good as a checkmate.

It improves your chess if you have a habit to resign in such a situation. Many players want to improve their chess. Don't you?

pawnstar it is because you don't really leaarn anything if you lose your queen like that. Much better to resign and learn something.
[by the way--I am, sure this is one reason why this situation was put in Queens Gambit.]
ponz: your answer is a nearly perfect example of circular reasoning. maybe what you say has some merit to it. (and maybe not.) but you certainly cant ascertain anything of value from what you have written. why would i not be able to learn anything once my queen is gone? be specific.
and, btw, i watched the queens gambit and in that situation the janitor was teaching the little girl about respect your your opponent. it had nothing to do with whether or not she was in a position to learn something without her queen.
ponz: the reason i am harping on this is that your position is the exact opposite of what i hear from people who coach beginners at chess. they always say to never resign. why would coaches tell their students to never resign if your premise about not learning anything with a queen is true? i totally get why more advanced players resign. if your opponent is not a beginner it is highly unlikely to overcome such a disadvantage. but again, your comment makes no sense on face value and is counter to what nearly every coach i have read teaches on this matter.

yeah as in respect that your opponent is good enough to win when a queen up, resign instead of watsting their time. if u play it out when a Queen down, u disrepect ur opponents skill and it is better to start a new game and improve on the mistakes made prior
In chess, the queen is considered the most powerful piece. As per my perspective, people quit because they feel they don't have enough material to play and when you think from that point of view then it's true that you just lost your most versatile piece on the board but just resigning from the game after you lost one piece is not good for your game. You have to understand there are many ways of playing the game. You should not demotivate yourself even if you are left with just a few pieces. There always will be a way to win. In fact, you can use pawn promotion to get the queen back in the game. Many players purposely sacrifice the queen and win the game. So quitting should not be an option.

In the Queens Gambit Respect your opponent was one of thje reasonms to resign-not the only reason.
Sure there was something of value in what I was stating. It was you will learn much more by playing from close to equal starting position than from a position where you have a huge material advantage.
I should have said you learn next to nothing once your queen is gone.---you learn next to nothing--it is about 200 to 300 level chess and you are 1100 are you not? Always try to play at your level or higher and then you will learn some good things.
Also I do not think you are a begginer at chess so a coach telling to resign at your level maybe thinks you are a beginner or is giving you bad coaching.
I have coached hundreds--maybe thousands. I have told you why you should resign in such a situation--you do not have to take my advice.
Also not all coaches advise a 1100 rated player to resign in your situation. [they may suggest to new players to do this]
It is very lazy for a 1100 rated player not to resign. Obviouisly I disagree with FM Aash20
