If you are playing Starcraft 2
multiplayer mode and want to win a match easily, try this: Just a few minutes before prime time
(in Germany and Austria, this is 20:15), start a match. If you are lucky, at about 20:15, your opponent will realize how late it is and leave the game, letting you win. Happend two times for me already (although I'm not sure this is the exact reason, but looks suspiciously like it).
