If you are looking for adult level chess books, we have many of those. My husbands chess books sit right above this computer. Most are fairly old since my husband doesn't spend a lot of time following chess anymore. Most of these are collections of famous games by grandmasters. This is one of the ways good chess players practice, is playing through other famous games. My husband would usually pull out a chess board when going over these games. I would imagine most these are probably a bit too dry for most kids, but if he is obsessed. A sample of book titles are "Opening Gambits", "How to play the Sicilian Defense", "World Champion at the Third Atempt" and "Chess Combinations as a Fine Art".
