Sofia Rules
that is kind of impolite, as your opponent may think that you are assuming that they can't checkmate. anyways if you're losing by a lot you deserve to lose even if your opponent can't checkmate as you made a blunder or your opponent had a combination you overlooked. it also shows you are a bad sport if you are desperate enough to draw a game that you play until the very end.
as with the draws it depends on what the draw position is. (at all times consider the king on the board)
One Pawn- you may as well draw if your opponent is USCF 800+ as he/she probably knows pawn promotions
A rook each, queen each- Draw, dont try and win this. any decent opponent will not let you win
Two Bishops, Three Knights- you can play this out, many people including me dont know these mates
both have bishops+ if you have less than 2 pawns ahead of your opponent
other than that i guess decide yourself
At the level you and I are at, this is fine. But, at the GM level, which is what the OP is talking about, that attitude is disrespectful. Any GM has already proven that they can do this by the fact that they are GMs.

Actually, queen versus queen has some surprising winning chances:
I am all for this, because I think that drawn positions should be proven drawn (Either by three-fold repetition, the fifty move rule or insufficient material). Would it kill the defender to play on until a draw is reached? I don't think so. What do you all think?
