NO BUT IT SHOW BAD SPORSTMANSHIP IDIOT!!!!!!!!!!!!!!!
Resigning
If you don't see any chance of victory on your side and I mean any chance than resgining is your best option. I think it's rather humble. You admit that you have lost and that your opponent win the game.

I think below 1200 you shouldn't resign. because players should be forced to demonstrate their endgame skills.
at the time I played in a club some couldn't mate with K+R vs K or draw theoretically drawn positions.
but as soon as you get better you will get a feel when it is pointless to play on or when to play on.

Doesn't anyone try for a clever (or lucky) stalemate anymore? It's an amazing feeling when I bamboozle my opponent by engineering a stalemate from a supposedly lost position. Of course that resource is not usually there, but you will not find it if you don't look for it.

How rude is it to not resign in a clearly lost game? I pretty much only do the turn-based chess and not live on here and I have some games going that I have clearly lost. Is it wrong of me to play until I get checkmated?
At your level, keep on playing, as stalemate is always a possibility.

I would not necesscarly say that. I was always taught that quiting before the end was bad sportsmanship.

briskit,
Anyone that wants to talk about sportsmanship, and then calls someone an idiot...ignore them. There opinion isnt worth listening to.
At your level, play on! Youll learn to know when its time to resign.

when I was 1100 rated and I trained against chessmaster 10. chessmaster 10 never resigns. It never does.
I think I learned a lot how to win a winning position and avoid stalemate traps that chessmaster 10 sets.
had chessmaster resigned like Fritz I doubt I would have learned as much as I did.
The time to resign is when it would no longer be any fun to play on.
I do not resign immediately when I am decisively behind in material if I can see some way to make my opponent's life difficult. And I get some fun from trying to conjure up threats in such positions. I don't think I have managed to turn any games like that around but if your opponent breathes a sigh of relief when they finally have the win in clear sight (and sometimes assure you that you are a tough opponent to beat) then that can be quite satisfying.
There seem to be a few people who complain when an opponent plays on in what they regards (usually rightly) as a completely hopeless position. I don't understand that (and would not resign merely to please such a person). If your opponent is still getting some satisfaction out of making their moves, however far behind they are, it is your business to look for the most straightforward or elegant way to end the contest, not to start moaning.
