Why do some players immediately resign the moment they lose the momentum? Is it ego? Pride? Shame?
there really is no point to ever resign.
That's the other end of the spectrum from this question. Why do some people never, ever, ever resign. Some positions are 100% going to result in a checkmate and they still don't resign. I don't get that. Like there are some very basic checkmates that follow a very common pattern. If a player takes the first 7 steps down that path and only the 8th step remains, you lost. All they do is deliver the knockout punch. Like when it's a rook vs king and they played it perfectly and you're on the back rank opposite their king and all they must do now is drop their rook. That player is never, ever, ever not going to mate you.
They might stalemate them. (I would totally do that.)
No, as blanket general rule of thumb this sounds nice but it's simply not accurate. Like when it's two queens vs a king. It's the simplest mate in chess. You walk the king to one end and have one queen on each rank and it's done. If a player starts doing that dance, you are about to get mated. From the first move you can argue maybe they don't know how to do it. But once they start doing it that doubt is gone. It's 100% about to be a mate.
No. Probably true for the two queens mate but not for other basic mates like mating a lone king with a queen. It’s totally possible to stalemate someone there. I can recall myself stalemating people in such positions.

Yes, of course this is the rational take on it.
But if someone has you backed in the corner, beating you with a stick for the whole game. It's a bit anticlimactic for them to simply resign when you've grabbed their stick and are about to start beating them with it.
It may be related to the league system.
To collect league points it is more efficient to resign a lost position and play another game.

It's very common in my games, 1100-1300 range. The player is very aggressive from the start and pretty much every move I'm on the defensive and they are attacking. Then they misstep and now I am up a knight or bishop, or even a pawn and I'm going to be the one attacking and they instantly resign. Their position is far from lost and my rating thanks them because they'd win or draw a lot if they played it out. It's just really weird that they do that. My best guess is that it's their bruised ego.
Yeah maybe.
Other than ego it might be they attack because they know they're trash at everything else, so they feel like once their attack is over they'll definitely lose.
It's been too many years since I've been 1300 so I don't know, but at higher levels it's funny because often attackers are terrible at defending. So in some games I'll carefully parry threats for 30 moves in a row, then when I finally get the chance to push back they fail after my 3rd threat lol. When that happens I always feel like...
There is also the psychological factor that after being attacking and pressing the whole game its more difficult to switch to a defensive gear.

Some people play just for fun, so if a player doesn't feel like they want to grind an objectively losing position, they resign. If you want to be as competetive as possible, you shouldnt resign. Theres not really a whole lot to think about there

really 1500 rated dudes who think they never lose once they get material advantage need to stop being delusional . Go watch the humbling botez gambit speedrun where Hikaru shows how even 2400s can't win up a queen if the stiffest resistance is put , especially online .

That is in Blitz versus way lower rated players that he can squise on the clock.

This is an example of a game where my opponent resigned as soon as he was in a losing position in 5/5 blitz. It seemed reasonable to do so, to me.
What? He was not even down a piece.
You linked the wrong game?

I lose or draw from positions like that all the time in blitz.

His position was wrecked and I had planty of time. It was 5/5, not 3/0 or something.
Engine says black is better. -0.9
Most likely he or she resigned by other reasons. Like something irl stuff.

He resigned simply because his king was exposed? Wow. That seems really premature to me. Unless there is a clear attack coming that I don't see.
I always play Danish Gambit when black opens with that pawn. Standard version they often decline but that way it's almost always accepted.

His position was wrecked and I had plenty of time. It was 5/5, not 3/0 or something.
5/5 is all I play.
Chess is a fight! And the best players are all great fighters. Just look at Nakamura or Carlsen when their back is to the wall. Mental toughness counts for more than technical knowledge
