Here's a great quote from the TV series Person of Interest (Season 4, Episode 11, 6/Jan/2015 entitled "If-Then-Else") that applies to business and innovation as much as it does to the game of chess.
Harold Finch describing the chess to The Machine - an artificial intelligence computer he designed:
"Each possible move represents a different game, a different universe in which you make a better move. By the second move, there are 72,084 possible games; By the third, 9 million; By the fourth, (... 318 billion). There are more possible games of chess than there are atoms in the universe. No one could possible predict them all, (not) even (... a computer), which means that that first move can be terrifying. It's the furtherest point from the end of the game. There's a virtually infinite sea of possibilities between you and the other side; But it also means that if you make a mistake, there's a nearly infinite amount of ways to fix it. So you should simply relax and play."
