In game theory a move by nature is a decision or move in an extensive form game made by a player who has no strategic interests in the outcome. The effect is to add a player, 'Nature' whose practical role is to act as a random number generator. For instance, a game of Poker requires a dealer to choose which cards a player is dealt, the dealer plays the role of the Nature player

Famous quotes containing the words move and/or nature:
“The idea was to prove at every foot of the way up that you were one of the elected and anointed ones who had the right stuff and could move higher and higher and even—ultimately, God willing, one day—that you might be able to join that special few at the very top, that elite who had the capacity to bring tears to men’s eyes, the very Brotherhood of the Right Stuff itself.”
—Tom Wolfe (b. 1931)
“Good nature and good sense must ever join;
To err is human, to forgive divine.”
—Alexander Pope (1688–1744)
