My DS nearly5 has become obsessed with chess. He got the game "No stress chess" 10 days ago and since then has played 1-2 hours every day - today it was more like 3-4 hours. He wakes up and the first thing out of his mouth is "Can we play chess?" And instead of reading at night he just wants to play chess. Does anyone know a good book that we can read to him that has a fictional character that enjoys playing chess? Or some other story about chess that might be enticing? Or something else that is about chess but maybe in a math/ science/ etc. kind of way ? Thanks!
