Should I Resign in lost position or not?


It depends on whether or not the lost position your playing has compensation.
——————————
It is considered Rude and even Disrespectful if you don’t resign a truly lost position.
It is bad etiquette and considered unsportsmanlike.
——————————-
However, it is also considered bad to resign in a tricky, complex, and/or losing position which has compensation.
No one likes a premature resigning player.
It is unsightly and unjustified.
In addition, Premature resigning can also cause your opponents to be very confused!
They will say statement like “Why did my opponent resign? I’m so confused?”
———————————
Knowing when to resign and knowing when not to resign takes skill.
You have to know when to cut your losses.
Time is extremely valuable.
If your spending all your time playing a losing game with no hope of ever making come back, Than you might run out of time and not be able to play another game or review game.
————————————
Furthermore, Its very important in chess to know when your losing and when your winning.
Knowing if your winning or losing can impact how you play or how you formulate your plans.
Very, very difficult to know if your winning or losing in chess game sometimes!
You could be down a Queen and pawns and yet be in a totally winning position.
It’s not always clear and that’s what makes chess tough game to master.

Here is an example of game I resign.
My opponent didn’t really beat me.
I gave my opponent the win with my sloppy, terrible play.
—————————
Sometimes, Resigning takes courage because it forces you to face the truth!
I played like hot garbage.
I played to leisurely and careless.
I gave my opponent the c4 pawn thinking I would get it back, but didn’t really have any follow up to get it back and my opponent decided to try and hold on to it causing me more problems.
I missed my opponents counter responses.
At 1 point in game my opponent played Nd5 hitting my Bishop, I didn’t want him to trade his Knight for my Dark bishop because it would wreck my pawn structure. I played Be5 with idea of doing bishop trade only to be meant with move f6.
I never even consider f6 as counter response from my opponent. Why not?
Why wasn’t the move f6 on my radar as possible candidate moves available to my opponent?
I should have been open to the possibility that my opponent would play it which could of helped me play a different move in that position.
It’s my fault!
In addition, I foolishly tried to play “Hope Chess” by taking my opponent Knight on d5 with my Knight as in between move. I knew if I retreated my Bishop. He would take it and wreck my pawns with his knight on d5 so I traded of his knight as in between move. My “HOPE” was that he would recapture my knight. Than I would move my Bishop afterward.
My opponent is good player. He doesn’t fall for tricks!
When you play like a Fool, your position ends up like a total joke!
He took my bishop. Than won a 2nd pawn.
I thought okay I am losing pawns. I need to try and win back some pawns so I played move Nh4 to try and win his undefended g6 pawn.
He responded with Qb6 defending his g6 pawn and attacking my undefended b2 pawn.
I moved up my Queen to defend b2 pawn and walked right into a Fork.
The Knight came in and attacked my Queen and Rook.
I thought if I just retreat with my Queen. He will win exchange + be up 2 pawns which is horrible. I thought maybe I can try force his Knight to take my Queen and I can try to take his Queen this is why I played pawn move a5.
I didn’t even calculate the ramifications of the move a5.
I didn’t even realize I screwed up even worse till he took the Queen with his Knight.
‘After my opponent takes my Queen, he can play Nf3 check.
‘I am losing even more material.
Than I had knee jerk reaction and decided I needed to take his knight first.
Than take his Queen second!
HELLO! You can’t do that because the opponent will move his Queen out of danger and not give you a chance to take his Queen second!
Terrible - What was I thinking? I wasn’t thinking!
I should have used more time!
I should have been more careful!
I resigned this game because I needed to learn my lesson from these mistakes!
These losses are what make us stronger.
———————————
I could have played on!
I could of tried to swindled a draw.
Or my opponents internet could of disconnected and I could of won due to game being abandoned by my opponent, right?
But does drawing or winning in such ways help me be better chess player?
I am not trying to win rating points from 1 game.
I am trying to win rating points from all the games I play.
It is a deeper more ambitious goal.

Do you understand?
Everybody will have their opinion about when to resign. My personal preference is to resign when I feel I have no chance of drawing when I'm down a significant amount of material. Complex positions or a time scramble is a reasonable reason to play on. Games that you feel that you shouldn't have won are just as important to review as your losses.

Only losers with weak minds resign, the sort who commit suicide when facing adverse circumstances in life, the real heroes fight till their last breath

The problem with resigning is that you aren't allowing the other player their opportunity to blunder.
But, if you are down 3 major pieces and see your opponent can mate you in 2 or 3 moves, then maybe, why waste each other's time on a hopeless game.
Well, you're a 1500-rated player so you're not really a beginner, and can probably judge fairly well whether your game is lost. It's only a game. Some people take a delight in good chess, a game won through interesting positions. Others enjoy the cut-and-thrust of extreme time-pressure, the satisfaction of watching an opponent blunder with only 5 seconds left on their clock. There is no right-or-wrong about these approaches. Some people care about every rating-point, others don't. If a particular game has no more enjoyment for you, because the bit you like is over, and if you don't think your opponent is going to get much fun from you playing on either, I can't see why resigning is a bad thing.
Personally, I will resign a game that I'm not enjoying, even if it's a won position. Life is too short to waste on stuff that's getting me nowhere, and I don't care tuppence for ratings. But not everyone feels like me, and that's fine.
Resign when you have no hope to draw or win.
Otherwise play on.

If you were terminally ill and in constant pain, I think that you might reconsider fighting to your last breath. If I knew you and assisted suicide was legal in your country, I would be more than happy to help you end your suffering.

Don't resign unless you're confident there's nothing left to play for. Your opponent is perfectly able and even likely to make mistakes during the conversion phase.
That said, aimlessly running your King around in a dead lost position is both not fun and not instructive. Unless your opponent is running very low on time, it's usually more efficient and fun to resign and play another game.

Resign when you feel that (both):
1) you are in a lost position without counter-play, and
2) there is nothing more that you can learn by continuing to resist.
Just play on until you are mated. When you are experinced enough you know when it is time. Most players do not resign until the move before they are mated.

You can't resign in a lost position. It's against the rules. According to the rules a lost position, such as a checkmate or disqualification, does not allow further action. The game is over, so resigning after the game is over is not allowed.
You could resign in a losing position though. But that depends on the circumstances. If your losing position is one where stalemate or time out is very possible I would say play on. Also if you and/or your opponent are low rated, definitely play on.

Also, if my opponent resigned when I was a few moves away from getting the “killer king” achievement, I would be very annoyed.
I do mainly play daily games, but I think of my opponent resigned in a position that I couldn’t guarantee mate, I would probably say something like, “well, I guess my rating went up. That could have been a fun endgame…”
So, if you’re playing another person and not a bot, I think you shouldn’t resign.
