welcome; glad you're having fun...that's the most important thing. you're hitting on one of the most popular topics that have appeared on various forums. some people seem to resign quickly; some not quick enough; it's all a matter of taste. this will continue to be a puzzle to you as it is to most of us here. good luck
when to resign?

hi! i'm pretty new to chess too and i think some of the resigns are made by opponent's psihology when they lose a big piece like queen or when they got checked (happened to me at live chess a couple of times when playing with people who's rating was near mine - beginners). i'd say when the beginners who think they know a little bit of chess do a mistake, they get angry and resign. i mean, we joined this community to learn (also from the mistakes) and play the game to the end, right? ..unless it's really the end with only king and a piece left. and i really think you won't see a player with medium or high rating resigning the game so easy.

One saying that really comes to mind is "it aint over until its over". Its truly amazing sometimes what happens after 45- 50 moves.
To me. Its whoever makes less mistakes will win the battle. A small error is one thing but not having the vision and missing something can really destroy you.
Only resign when mate is eminent. Then do it with grace and class.
Hi - I'm fairly new at all of this but having fun + learning a lot.
One thing I don't get sometimes when studying games is why a player resigns. Sometimes it's obvious but lots of times it isn't (to me at least :-) since it seems like there are moves still to be made. Am I just not seeing ahead far enough?
This is probably true in my own games too - when I don't see that I've lost. (of course in beginner chess, the opponent can always make a fatal error...)
Anyway - I'd be interested to hear any thoughts or get links to articles, etc.
