On the subject of cheating, I have a little different angle.
I am not a great chess player, somewhere below 1500 I'd guess. But I do enjoy playing with other not-very-good players. I am better enough than my children to never lose to them so far. But I would like them to enjoy the game. It doesn't seem very fun if you don't have some reasonable chance to win occasionally.
This creates a situation where I have an incentive to cheat very creatively so that my child has to work for it and doesn't detect the reverse-cheat that allowed them to win.
