Good etiquette in using Resign?

Although frequently seen in tournament chats, it is extremely unfair to tell opponents during a game: "You are lost, resign." It does not get better, if you say "Please". It is entirely fine to play until mate in a completely hopeless position, if you make your moves fast. There is no obligation whatsoever to resign. But of course it is highly unfair to just let the clock run and delay the inevitable end only to annoy the opponent.

"But of course it is highly unfair to just let the clock run and delay the inevitable end only to annoy the opponent."

I wouldn't say it is unfair. It is extremely rude, but it is within the boundaries of the rules, and therefore fair.

Unless you think the rules are not fair - which is a different question altogether.

I have people playing on a rook down, two rooks down, two rooks and a piece down....these people really annoy me do they think I am too stupid to win with such massive material advantage? that is what it feels like they are saying and it is unsportsmanlike.
When I played on ICC for 17 years people resigned with grace instead of playing on with no hope whatsoever of recovering their game...its called class

tell it to magnus carlsen. He's been in a known drawn end game against another super gm and played on for tricks. they didn't work because everyone knows tricks are for kids. he eventually accepted a draw.

I think if you know your opponent and know they will with 100% certainty win, then resign. I don't think you really know that when playing random people on the internet and you both aren't above 2200

as long as you (or they) are not deliberately wasting time, then no harm no foul.

Playing on in a drawn endgame is a little different than playing on a rook down don't you think?

This may go against the current social grain but I think it's more important to refrain from resigning even in lost positions because you never know what your opponent will do. Still not sure if the psychology of this changes between online and OTB tournament play, but it seems unfairly aggressive to expect your opponent to resign in some given position. I'm just saying that personally I'm not offended when people don't dip out of the game instead of putting up a creative fight.

After the mouse slip I still managed to win.

#26 yes I do think. when 2 super gms are playing a known drawn end game they aren't going to blunder, like ever, and the game is going to end in a draw every time no matter how many tricks are tried.

whereas if two random people on lichess who aren't gms play each other and one loses a rook, anything could happen, it could be a win, loss or draw.

@ambrooks. #23. I completely agree. it's stupid and a waste of time. but fair. just like "flagging". everyone is allowed to do it.

I resign a lot. Some people don't.

As for the OP's claim that people resign more on chess.com than lichess, I have no idea if that's true, but I don't see why it would be.
