When my daughter was little, we played "turn around chess". She could, at any time, start her turn by turning the board around and taking over my position. I simply played my best chess (which isn't all that great, frankly) and when she felt cornered she would turn the board around and get the opportunity to attack from a superior position while I would try to fight my way out.<p>We both had a lot of fun, and I didn't have to do anything fake to make it fun for her.
