Did you tell your opponent what had happened? I have had people ask for draws without explanation and so I just ignored their request. It was not my intention to be rude when I did so. I simply did not know who the person and had no compassion toward them due to the nature of this setting.
My beef with rudeness comes from trolls who feel the need to comment and taunt.
Today after winning and losing a game to a person we played a tie braker for fun. I mouse slipped my 2nd move and then asked for a draw and fourth game as the tie braker (he would even get his rating up seeing as I was higher then him). He refused and kept playing and I couldn't understand why it seems just outragousely rude. Anyways I went through with the game drudged along and he blundered and I mated. But I just want to know why oh why would someone not accept the draw and play another game.
