Hocus pocus double focus
In the late 1940s, the British magician David Berglas started refining a trick that came to be known as “the holy grail of card magic.” […] The trick is a version of a classic plot of magic, called Any Card at Any Number. These tricks are called ACAAN in the business.
ACAAN has been around since the 1700s, and every iteration unfolds in roughly the same way: A spectator is asked to name any card in a deck — let’s say the nine of clubs. Another is asked to name any number between one and 52 — let’s say 31.
The cards are dealt face up, one by one. The 31st card revealed is, of course, the nine of clubs. Cue the gasps.
There are hundreds of ACAAN variations, and you’d be hard pressed to find a professional card magician without at least one in his or her repertoire. (A Buddha-like maestro in Spain, Dani DaOrtiz, knows about 60.) There are ACAANs in which the card-choosing spectator writes down the named card in secrecy; ACAANs in which the spectator shuffles the deck; ACAANs in which every other card turns out to be blank.
For all their differences, every ACAAN has one feature in common: At some point, the magician touches the cards. The touch might be imperceptible, it might appear entirely innocent. But the cards are always touched.
With one exception: David Berglas’s ACAAN. He would place the cards on a table and he didn’t handle them again until after the revelation and during the applause.
