DS17 used to play chess as a kid and has got back into playing it in the common room at school recently, as well as online. Just wondered if there was anything chessy that might make a good smallish gift? He probably wouldn't sit and read a standard chess book from cover to cover- he's just playing for fun so no interest in learning loads of openings or whatever. Already has a set. Wouldn't want a normal item with a chess theme eg mug or tshirt.
It may be that no such thing exists but I don't know much about the world of chess so thought I would ask.
