I've got a theory about the players who gives you extra time when they are winning. They delude themselves thinking they do it out of generosity, but they don't... They want to enjoy seeing their opponent in trouble, they want to prolongue the agony and the extasis of checkmating him. It is sadism, not generosity. They will never give you extra time when you are winning but having problems with the clock. Hey, I dont want your miserable extra seconds!
