why you should play chess

Chess and Mathematics.  You don't have to be a genius to figure this one out.  Chess involves an infinite number of calculations, anything from counting the number of attackers and defenders in the event of a simple exchange to calculating lengthy continuations.  And you use your head to calculate, not some little machine.
 

Chess and Research.  There are millions of chess resources out there for every aspect of the game.  You can even collect your own chess library.  In life, is it important to know how to find, organize and use boundless amounts of information.  Chess gives you a perfect example and opportunity to do just that.
 

Chess and Art.  In the Great Soviet Encyclopedia chess is defined as "an art appearing in the form of a game."  If you thought you could never be an artist, chess proves you wrong.  Chess enables the artist hiding within you to come out.  Your imagination will run wild with endless possibilities on the 64 squares.  You will paint pictures in your mind of ideal positions and perfect outposts for your soldiers.  As a chess artist you will have an original style and personality.
 

Chess and Psychology.  Chess is a test of patience, nerves, will-power and concentration.  It enhances your ability to interact with other people.  It tests your sportsmanship in a competitive environment.
