That is pretty awesome!

Your amazing

This trick is great but it doesn't work if they deal the cards into piles of 9 or 10 because afterwards, when we pretend to go over it again, their card will end up in the second pile, which we shuffle, rather than the first one.

this is one of the best tricks that I have seen

It was very nice that you recognized Andy. I would just like to mention that you too, have given the next generation a foundation for this wonderful world of card "Magic". You and yours are NOT destroying the secrets IMO. You are teaching, which makes it fun to learn and you are inspiring beginners to alter and create. This will guide a fresh generation and give them the backbone they need to keep it all going. Thanks so much!
