Think of a card - The real stuff

A friend sent me an article about a research that explores the idea that there is a ‘random number generator' in our brain, and that is possible to know the number measuring a person's vertical and horizontal eye position.

Maybe this can be applied to magic. Imagine that you ask an spectator to think of a card: first of all he needs to think of a number from 1 to 13 and stick to it, and then think of a suit.

If here are patterns in the position of our eyes when we think of numbers and suits it would be possible to predict the exact card!

Close-up week magic on ‘The Late Show with David Letterman’ - May 2010

Last week (17th to 21st May) was the "Close-Up Magic Week" on The Late Show with David Letterman.

The show featured some of the world's best sleight-of-hand magicians: magician Jason Randal, John Carney, Johnny "Ace" Palmer, Steve Cohen and Michael Ammar.

Ammar’ performance was interesting and he included several items from his current lecture. Jason Randal, on the other hand, seemed to be quite nervous, more than a professional should be. The fact that Letterman was continuously interrupting him didn’t help at all his performance. I wonder why he didn’t made use of the opportunity of doing a color change when he was challenged by Letterman to repeat the effect ‘without the plastic folder’.

My favourite performance was John Carney’. Only after watching his performance I read on Genii that he also encountered some problems when performing at the show. In his own words <> Genii Magazine

As you can see the line-up is top notch, however the material chosen for the performance was not up to my expectations. Probably everybody opted to play it safe because they know that Letterman is a pain in the b*tt as an audience 

See below the videos in case you missed the show!

Tuesday 18th of May 2010: John Carney


Wednesday 19th of May 2010: Johnny Ace Palmer

Hofzinser Aces

The effect
The 4 aces are placed on the table and a card is selected and lost in the deck. The aces are shown one at a time and asked if they match the suit of the card chosen. The ace that matches matches the suit changes into the chosen card.

Comments
The plot was popularised by Hofzinser almost 200 years ago. Since then magicians have worked on it and created hundreds of methods to achieve this effect.

I have been thinking about this effect for a while. In my opinion, to obtain the greatest impact with this plot the following is required:

a) The spectator must be left with the feeling that any card could have been selected.
b) The aces must be kept away from the deck prior to the moment the card is chosen.
c) The aces are shown in the fairest way possible, and the one that matched the selection' suit changes into the selection.

Darwin Ortiz has taken the most direct approach to the effect and meets the main points that make this effect “magical”' with the exception of the selection process of the card. In my view this is the problem with Darwin' version of the effect. I don’t think that the riffle force is the most adequate to satisfy the first requisite.

On Benjamin Earl's version the card is selected freely but the aces are not put aside: only when the card is chosen and lost in to the deck the aces are produced. This means that the second requisite is not met.

For this reasons I conclude that the best version of the effect is, in my view, Michael Skinners Telltale Aces since it meets all the requisites, however I still have a soft spot for Benjamin Earl' version.

My favorite solution
Benjamin Earl: can be found in Past Midnight Vol. 1



Resources
Also worth checking:
- Darwin Ortiz version in Cardshark (known as the original in german: Kartenkunste)
- Hofzy Hofsbourne by the Twins
- Roberto Giobbi' Card College, for an elegant and simple solution
- Mike Skinner's Telltale Aces. The beauty of this version is that the ace changes into the selection and back into an ace, and that the spectator can examine the aces

The Zarrow Shuffle

Zarrow shuffle was invented in the 1940's by magician Herb Zarrow. Is a sleight of hand technique that gives the appearance of being a normal riffle shuffle, but in fact leaves the cards in exactly the same order.

As David Britland states in Phantoms of the Card table "[Zarrow] created a false riffle shuffle of such beauty that it is quite possibly the only move to have been originated by a magician and that has found its way into world of card cheating."

The shuffle is easy to learn but difficult to master




RESOURCES

One of the best resources out there is the DVD by Mr Zarrow himself. On this DVD Mr. Zarrow teaches how to execute the shuffle in great detail and with many variations. Although the DVD centers around applications for magic most of the information can also be used for false shuffles, culls and controls during play.Find it here.

You can also find a description in Giobbi's Card College Volume 3.

For more references, please check Denis Behr Archive Resources on the Zarrow Shuffle:

There are many variations of the Zarrow shuffle, one of the most popular ones is describen in a manuscrit by Gary Plants: Gary Plants on the Zarrow Shuffle is now quite relevant.
