All warfare is based on deception .. If your opponent is of choleric temper, seek to irritate him. Pretend to be weak, that he may grow arrogant .. To see victory only when it is within the ken of the common herd is not the acme of excellence. To lift an autumn hair is no sign of great strength; to see the sun and moon is no sign of sharp sight; to hear the noise of thunder is no sign of a quick ear. Sun Tzu The Art of War
