According to Kasparov "What separates a winner from a loser at the grand-master level is the willingness to do the unthinkable. A brilliant strategy is, certainly, a matter of intelligence, but intelligence without audaciousness is not enough. Given the opportunity, I must have the guts to explode the game, to upend my opponent's thinking and, in so doing, unnerve him.

So it is in business: One does not succeed by sticking to convention. When your opponent can easily anticipate every move you make, your strategy deteriorates and becomes commoditized. So, yes, a sort of courage is paramount. But that courage must be tempered by other less-glamorous qualities.
