Chess first of all teaches you to be objective.
Chess is a matter of vanity.
I believe that true beauty of chess is more than enough to satisfy all possible demands.
Chess is not only knowledge and logic
Young players expose themselves to grave risks when they blindly imitate the innovations of masters without themselves first checking all the details and consequences of these innovations.
In my opinion, a master is morally obliged to seize every sort of opportunity and to try to solve the problems of the position without fear of some simplifications.
