The ultimate reason why you should never ever ever ever ever ever resign...

...because the old geezer can fall back from his chair and actually die!

I do refer to online correspondence chess.

By the same logic you should never check or mate.

Why?

I don't understand why decorum dictates one should resign from the ultima thule...point of no return.

I mean a logical person should evaluate ALL possibilities. Suppose you are a checkmate away (give or take three moves) but 14 days left. There IS a slight chance that if you are playing Gunter, aged 92 might actually kick the bucket any time.

So given that plausible scenario a player should never ever resign because you can't just predict what's gonna happen next instead of getting pestered by 13 year olds with a smarmy smile that 'hey! i am 19 points up plus a queen and a knight...you can click the resign button'

Aagard's Right Decisions CD has a position where white resigned a winning position but could have forced checkmate with pawns. 

Please don't say things like this, it's so tedious spending two months winning with two extra pieces.

What do you actually achieve if your opponent times out in a winning position?

I think the post was meant ironically. Nevertheless, your question is way more interesting: What do people try to achieve by using tactics that have nothing to do with chess just to win a game? It's understandable on a very high level, where these things can make a difference in your checkbook but for people who play for fun it seems to be highly pointless.

SniperClown, you are really a 'clown'. Using the example of someone die because a trivia chess. Well, I think it is a good way to create a conversation on this site that seems to filled with only serious minded-like people. They do not want to chat.
