How is it swindling if you have all agreed to play a fair game?

You do have incomplete information, but to the extent you describe it only exists within a single hand. If you play for a couple of hours, you get more information. That's the point. You're not playing the cards, you're playing the people holding them.

And that's a great allegory for life, and you can learn a lot that will help you in life in general.

As such, I find people who don't teach poker to their own children - like yourself - are, to me, utterly incomprehensible.
