Sun-Tzu: "The Art of War". He was a warrior. A book written in China 500 years before the Bible was put together. Get it and read it. Nothing has changed since then. I have it. What you meant to say is:
"If you are strong, act weak. If you are weak, act strong."
If you are strong, act weak...
Like I have said. Fred has read that...
Also the parts about the enemy of my enemy and choosing the battlefield...
Look at his campaign...
