I found something that explains why everyone should play chess.

Many people believe that playing chess is a waste of time because it is just a game and doesn’t have any real benefits. That is not the case. Chess has many benefits for your brain. Perhaps the most important one can raise your IQ. Playing chess involves constant decision making and problem solving.

A study of 4,000 students in Venezuela demonstrated a significant IQ increase just after 4 months of chess. Another big benefit of playing chess is memory improvement. A study of six-graders in the U.S. demonstrated the correlation of playing chess, improvement in memory and organizational skills.

Playing chess also has many other benefits including preventing Alzheimer’s disease, increasing your creativity, improving concentration, reading skills and even growing additional dendrites – tree-like neural cell connections in the brain.
