Psychologists often cite chess as an effective way to improve your memory. It also allows you to solve complex problems and think through ideas. Unsurprisingly, chess has come to be recommended in the fight against Alzheimer’s disease. Many people believe that chess is a game for those who are naturally highly intelligent. This is partly true, but you can also significantly increase your intelligence by playing chess. What’s more, research has shown that chess activates both hemispheres of the brain, improving creativity, concentration, critical thinking, and reading skills.
