Psnype by Kevin Parker

The spectator is given a deck of cards. Magician turns his back to him and tells him to cut the deck to any card he wants and peek at it. After spectator peeks at card, magician tells him the card he peeked at without asking any questions or touching the deck. It's as if he saw it while his back was turned.

• Uses no svengali, no assistance, no mirrors.
• Deck can be examined before and after
  
• Back is turned to spectator immediately after handing him the deck and while he peeks at the card
• Very easy to do, instantly repeatable
