Impossible Thought by Stefano Nobile

Hi friends magicians,i present my new acaan!
A card just thought of among so many shown is located at the exact number (1-52) that the viewer will say without strange movements (cuts or manipolation).You will sue a regular deck to performance this small miracle!
Important:
In the performance the count until the end i do it myself but i remember that once shown to the viewer the mimic of the movement that will have to do (the passage from above to under the cards) the deck will he handed over to the spectator and he will continue until the final revelation!
Easy to do
Incredible!
Thanks to all.
