Metaphors and chess

This isn't a metaphor really, but rather uses a general "chess/life metaphor" to present a particular point.

In life, as in chess, planning should be flexible and consist of short-range manouvers designed to improve one's position. Planning too far ahead can often lead one to ignore changes in the surrounding position, and thus miss important opportunities.

-Mongo, Blazing Saddles

yeah, slightly OT, but this thread suddenly brought this quote into my mind for some reason..

Chess is the universe, filled with almost infinite possibilities.
