Hi JB - if your son is still into Wizard's chess, you can play it on the Wii game Harry Potter and the Order of the Phoenix. I believe you can give your level of play at some point.

Do you happen to know whether the chess game is for casual play or can actually take good players?
Sorry - I don't know. We're just casual chess players here, and DS hasn't used it for awhile (and it was on pretty easy mode then.) But it was very fun to watch DS5 waving his wii-wand and shouting "expelliarmus!" during the other parts of the game.
