Many players feel just the opposite: that dragging out a hopelessly lost game is poor sportsmanship. Different strokes for different folks.
Isin't resigning being a sore loser?

it is Chess, not a basketball game! Sometimes in chess the fat lady has sung before the actual inevitable moves are played out. Why waist time tryng to defend a hopelessly lost position when you can resign and play another.
Now if you still have drawing chances keep fighting, but if you know you are in a forced mate in 3, then resign. The sportsmanship of resigning and tipping your king in chess, is the equivelent of Kneeling on the ball to run out the clock in American football.

I Isin't the honorable thing to finish your fight that you started?
Resignation is usually the acknowledgement that the fight IS finished. There is no "honor" in playing out the inevitable defeat. At best, it's pointlessly stroking the ego of the victor; at worst, it's either wasting his time, or perhaps saying "even though I have a lost game, I have enough disrespect for your playing ability that I still think I can either win or draw."
Sometimes acknowledging defeat IS the only "honorable" thing to do, which is why it is "chess etiquette" to do so.

Resign..... do not encourage these players on this site not to resign.
If you play several games that is what you want when you are winning that game. Good for both sides as they can go and focus on other games that they can win. This attitude of not resigning has carried over to Vote Chess.

If you're down a queen it's pretty much finished eh?
OP was talking about dropping a queen, like this:

Not on this site.
Welcome to Chess Players Gone Wild.
I should protest to get the name changed ...... lol.

Resigning is the honorable thing to do.
It is 9-year-olds and no-lifers who drag a dead lost game on and on just to annoy their opponent.

LIke i said on ChessPlayersGoneWild.com i have seen grown adults do it...... several of them. And they enjoyed it. Play Vote Chess and most like the game will end in mate no matter what your advantage. Why i work on methods in VC to force a resign.

I mean I feel like I am quitting in the middle of the game especially if you resign right after a major blunder (like of you drop your queen) or something like that. Isin't the honorable thing to finish your fight that you started? Why is it chess ettiqute to resign?
It is not chess ettiquete to resign. It is a personal choice when to resign.

It goes back to the middle ages, when 2 knjghts were fighting and one gained a winning advantage, the other would "yield". Or die.

It is chess Ettiqueette to resign .....when your 12+ down against an opponent with a way higher rank. Nothing to gain. The result can lead to the guy just going out and do:
1) Get 2 Queens on the boar.
2) Snatch each an every pice of yours then mate you in a game.
3) Play the game out till just 1-2 moves before it could be considered a draw.
4) Check you to see how many consecutive checks they can get in a game.
5) Force your opponent all the way to your side of the board then mate him(horrible)
Need i go on.

The title was perhaps provocative to many, but I have a different answer: neither need to be connected to chess etiquette.
Now, non-resigners could be the following:
1. People who think they are going to lose, and think their opponent will win (someone should point out to me how this is disrespecting your opponent's playing ability) but figure even if that's true, there is no net loss for them to play on as their result can only be as bad as they predicted (a loss); not worse. So they take a free lottery ticket and use it.
2. Or, they actually do think their opponent can't win the game.
Nobody should pretend like they can read their opponent's mind, and arbitrarily put them into one of these categories.

"1) Get 2 Queens on the boar.
2) Snatch each an every pice of yours then mate you in a game.
3) Play the game out till just 1-2 moves before it could be considered a draw.
4) Check you to see how many consecutive checks they can get in a game.
5) Force your opponent all the way to your side of the board then mate him(horrible)
Need i go on."
Because of the free lottery ticket idea, only someone with poor logical skills would think they know their opponent is an idiot for playing on. In exchange for a .000001% chance to win or draw the game, I personally wouldn't play on there, but I respect those who do.

This is all coming from a 1900 player USCF. This is not about chess ability; this is simply a logical principle: You can know your position is lost, but see no possible loss in playing it anyway.
You might not gain anything either, but the only thing you know 100% sure (and there aren't many things in the world we know with 100% certainty!), is that you won't lose anything.

You do; it is up to the person whether he considers playing on worth the extra time in his life. Generally, though, the lost time is hardly significant. But if he wants to devote 5 hours just to try to save a position that is totally lost anyway...
Well, that's no problem at all. Maybe he was 99% sure I would win the position; it's my responsibility to make him 100% sure.
"I'm two rooks up. Nothing but bare kings. It looks unlikely. Will I hallucinate? Will I move in for the kill too quickly and miss something stupid, perhaps something un-missable?"
I'll be happy to give my opponent a peace of mind (no pun intended of course!) and end the conspiracy theory.

A blundering of a queen might be devastating for one side, however It is not a won game yet. The rules of chess do not state that if the queen is lost the game is over nor does it state that any loss of material warrents the termination of a game. Fight! Your opponent still must win, and if his technique is poor he might have a hard time. If your opponent becomes frustrated that they cannot finish you off it is not all of a sudden disrespectful. It is a sign that their is still some fight left or your opponent needs some serious work in the technique department. Never give up, never surrender. Even if you see a checkmate around the corner, your opponent may not ;).
