Gadget Daddy: A chess-teaching rat gets an update for modern times Lonnie Brown Nearly 20 years ago, I wrote about a chess-teaching program aimed at children ages 8 and up. It used various arcade-like games to teach kids how chess pieces moved and captured. It was a new concept in learning chess for beginners. The program originally appeared in 2003 and was sold on a CD-ROM under the title of "Learn to Play Chess with Fritz and Chesster." Children's Technology Review wrote about it when it first appeared, saying, "clever review of the chess pieces and moves," and concluded with: "This is the best children's chess program on the market."
