heck yeah... totally annoying and childish
I was Criticised by opponent for not resigning when I blew a whole piece in the opening?

It isn't about chat. It's about someone running out the clock instead of just resigning. It's not a state affair. It is annoying and childish.


I continued playing even after loosing the queen....never resign...fight till the last move...till you are mated continue to fight.... i have won a game after making 100 moves !!!

Personally, I rarely resign. Sometimes when the position is absolutely hopeless, but even then a) opponents sometimes blunder stalemates b) practice at playing defensively is useful.
But certainly, going a minor piece down 12 moves in - there is no need or expectation to resign, you could easily come back from there, especially if you have 2 pawns in compensation.
Absolutely no obligation to resign, ever.
Just don't abandon the game or run your clock out because that makes you a total w*nker. If you want to quit, resignation is the ONLY acceptable alternative.
