Well, let me say what I understand...
Most people here are defending someone who is ready to lose his time and his opponent's aiming only "not to lose rating".
Firstly, the assumption that giordanobruno was "provoked" by the poster's attitude to let the clock run is incredibly gullible. It seems as it never happens you to have a crushing superiority (like K + R +pawns vs K) and that the opponent fight until he sees the mate in one, and then let the clock run / disconnects ?
The "all-queens" promotion might have been childish, that's true, but that's only after the opponent told the poster " i think you're an idiot and you cannot win with 4 pawns vs bare king on the other side of the board".
I admit that i would myself have felt insulted ; i usually promote to a rook when the opponent seems to think that K+p vs K is drawing even when the pawn go to promotion (unless lacking time).
Who could stay calm after a game where you proved you are no idiot and when the opponent still wants to lose it "by the rules" ? See professional player's games, they sometimes resign even because of one pawn lost without compensation.
Resigning is only proving you're wise enough to know you have lost and respectful enough to think your opponent can prove it.
I've seen even more losers who only have a bare king and stalls for over a minute then moving when the winning side has only 30 seconds left. But still, we didn't complain.
But you... you are a disappointment.
That is different. I won many of my games, with material down, where I just + opponents king, and lose a piece. After every + he took 2 sec to realize what is going on, and 2 more to capture my piece or move king. And I won those game on time. But that is not the same.
