By your logic, one could have seriously hampered your self confidence by suggesting that your reasoning about this is faulty, and the only reason you beat your parents at chess was because they werent very good at it.

I dont mean to be coming across as rude, but I believe the better way to handle the six year old is to encourage the process of creativity and imagination. There are enough people in his life (at least a Quadrupillion!!) that will try to tell him that hes being impractical and unrealistic, no need to add to that count.
