It's true you should never resign

I though I had my opponent, but he completely flattened me in the end-game, it was impressive!

Honestly, At times resigning is better, particularly if both players are high elo and know about things Like stalemate threats, Checkmate threats etc, There is almost no use in continuing playing, Unless you spot a crazy tactic before resignation.

YOU WERE COMPLETELY WINNING!!!

Why did you resign?

I resigned against a GM when I had a betyer position. Forgot I was taking back with check gaining a move. So yeah. Always play your best to the death. It shows emotional resilience.

You probably linked the wrong game. In the game shown, nothing of that sort happened.

This is probably my worst decision to resign - I look back and just don't know what I was thinking! Probably something along the lines of 'Oh no, I've lost my queen. Yes, can't do anything about that at all - I'm in check and my queen is hit. Blocking with the bishops is no good - I just lose my queen. Yep, my queen is absolutely lost and there's nothing I can do about it - where's the resign button'. Idiot.

Yes , sometimes you can even win from a completely lost Position . And it Holds true for Almost All Levels unless you are an Super GM . Have a look how one of my games went from completely lost to won .

I was at an event and a 14 year old 1800 was completely lost against a master but he kept playing on. Disgusted about opponent not resigning so could move on to the next round which was soon to start he then just started promoting his pawns into knights. After the 4th knight promotion the kid got that he was being disrespected in return and resigned.

I don't ever resign any blitz or bullet, and in classical and rapid I'll only resign if my opponent has mate or im down a ton of material

TL;DR: think more when you're losing, use human psychology, if there's a 50/50 chance of recovery, take it, try to stalemate in a completely lost endgame.

My advice is, if you blunder, you're going to tilt. It's human psychology. Take more time to make moves, it's normal to think more when losing, even GMs do so. Find simple tactics that your opponent might not notice. I'll take my own game as an example:

Here, I was playing black. My queen got trapped, and i tilted, and lost my rook and minor piece. I was down 11 points of material at my worst. Still, i didn't resign. Why? Idk, i think it was my first game of the day. There seemed to be no hope. But I made one last desperate attempt. If you see in the game, i sacrificed my bishop. If he took with the queen, then I was done for, but if he took with the pawn, I had a royal fork. The rest of the game my opponent counter-tilted and I won.

If you're losing in an endgame, set a stalemate trap.

*Sometimes* it is less painful to just end the game. Just because your opponent doesn't know how to mate with a queen doesn't mean you can't end it.
