Never interrupt your enemy when he is making a mistake.

It is an approved maxim in war, never to do what the enemy wishes you to do, for this reason alone, that he desires it.

Experience teaches that silence terrifies the most.

I play my enemies like a game of chess.

One must change one's tactics every ten years if one wishes to maintain one's superiority.
