Coincidence Incredible Card Trick Performance and Tutorial

Coincidence Incredible Card Trick Performance and Tutorial.
This is my favourite version of a Dai Vernon classic card trick.
I have previously published a video titled Coincidence Extraordinary, but I personally much prefer this version of the effect.
The magician gives a spectator the four aces and the spectator freely shuffles a pack of cards.
The magician then splits the pack into a number of piles of cards.
The spectator can then use their four aces to select four of the piles.
Even though the cards were shuffled and the spectator had a free choice of piles, the magician reveals an incredible coincidence.
After the performance of this totally impromptu trick, is an easy to learn tutorial.
