I enjoyed playing chess back in school. I really got into Yahoo and Lycos chess back when it was still popular. I beat a Master (maybe Senior Master) level chess player in high school, but that's a story for another day. I don't play so much these days. Like Waverly, all the secrets I once knew are gone.
You may not have to "let" your daughter win for too long. She might get good enough to just win outright. Young minds pick up the game fast.
