re: "Playing chess with a child is not a fair game. When you have years of experience, you have an advantage."
Chess is a competition. There is a winner and a loser.
Do you think romantic relationships are like that too? Does your marriage have a winner and a loser? Were you competing with your girl/boyfriend when you were 20? Did you win? or did he/she win?
(hint: your analogy doesn't work in this case at all)
