For younger kids it can promote problem-solving skills and potentially improve math and reading abilities [1] and it is a part of the public school curriculum in over 30 countries. But solving chess problems is not only beneficial for the young. It can also have similar effects on adults; increasing IQ and possibly warding off diseases like Alzheimer’s [2].
