Garry Kasparov, many people’s choice as the best chess player ever, said, “Chess helps you to concentrate, improve your logic. It teaches you to play by the rules and take responsibility for your actions, how to problem-solve in an uncertain environment.”

Bridge players can relate to that. Interestingly, though, the environment is less certain in bridge, where there are unseen cards, than in chess, where the position of every piece is known.
