why you should play chess

Chess develops memory.  The chess theory is complicated and many players memorize different opening variations.  You will also learn to recognize various patterns and remember lengthy variations.
 

Chess improves concentration.  During the game you are focused on only one main goal- to checkmate and become the victor.
 

Chess develops logical thinking.  Chess requires some understanding of logical strategy.  For example you will know that it is important to bring your pieces out into the game at the beginning, to keep your king safe at all times, not to make big weaknesses in your position and not to blunder your pieces away for free.  (Although you will find yourself doing that occasionally through your chess chess career.  Mistakes are inevitable and chess, like life, is a never ending learning process.)
 

Chess develops imagination and creativity.  It encourages you to be inventive.  There are an indefinite amount of beautiful combinations yet to be constructed.
