Want stimulating exercise for your mind? You may find playing chess a pleasant way to get it. Chess players meet every Tuesday at 1:00 p.m. to learn strategies and play games. Learning activities include explanation of moves on a large demonstration chess board, videos, and actual practice of strategies. Players often write down each move in a game using a modern chess notation system. Later they analyze the game and learn from it. Players also use special chess clocks to time each player’s moves. And there’s more.
