SPELLBOUND by Raphael Czaja

Effect: Using a full deck of playing cards, a spectator cuts to one card that the magician asks him to remember. He selects a second card by secretly spelling the name of his thought-of card, dealing one card for each letter, and pockets it. In the first climax, the magician is able to divine the card that the spectator is thinking of. In the second climax, the pocketed card and a prediction (tabled from the beginning) are revealed: They are identical!

No gaff. No sleight. Basically self-working. This routine uses a regular deck and an ordinary odd-backed card only. Everything can be examined.
