As an educator, I have found chess to be an invaluable teaching tool.
Most students readily recognize the game.
It is played all over the world and for thousands of years. It has a body of literature and highly visible support groups and enthusiasts. There are always volunteers ready to come down and play simuls or give lessons to the students. I have seen children who wouldn't sit still for two seconds puzzle minutes over a series of exchanges. For several years, I hosted a very successful chess club.
