I got my DS11 playing with me at age 5, and he does occasionally play at school, but doesn't yet like it, and will only play with me as part of a bargain of some kind. I really like it, and am still trying to figure out how to use Playchess.com
I can still beat DS11, but we have exciting games. When he was 5 he had lots of trouble with 'flow of ideas' being too meager, and I think playing helped him both to develop lots of plans, gracefully change plans, and the value of following the suggested stratagies, because if he brings out his Queen early, I eat it for lunch!
Enjoy!
