I think it was Sun Tzu who said,
‘Always announce your intentions to the entire world and in a show of good sportsmanship, give your enemy time to prepare.’
Love it!
Also I like:
1- “He will win who knows when to fight and when not to fight.”
2- “Build your opponent a golden bridge to retreat across.”
**My favorite
3- “The whole secret lies in confusing the enemy, so that he cannot fathom our real intent.”
