With regard to playing with any variety of control or combo: sometimes, whether I win or lose is determined by the next two cards I draw. I'll usually ask my opponent if I can peek at the top two of my library to determine whether I should concede now or play it out. My opponent usually agrees, and about 2/3ths of the time I'll concede.
Edit: is it a dick move to concede the turn before my opponent has the satisfaction of killing me with a surefire lethal attack? I usually do- not out of spite, but just to speed things up.
