The Red and the Black

If you’re interested in mathematical and gambling material you might find it worth it trawling through the following. It’s the history of a red/black proposition bet and a collection of various published ideas leading to what I think is an entertaining betting routine that seems to have been forgotten. I’ll describe the various aspects of the trick and interrupt along the way to let know a little more about the background and history



My minor addition to this is that you use some marked cards to give you an edge in this game that probability will not. Only two black spot cards in the deck need to be marked in a way that you can distinguish them.  If you want to use them in all the routines that follow, then I suggest you mark them at the corners. Alternatively, you can use a one-way deck, the black cards turned in the opposite direction to the red cards.

RED BLACK PROPOSITION BET
Let’s say the two black cards are the 8C and 9S.  Begin the routine by taking out four playing cards from the deck. Two are red spot cards and two are your marked black spot cards.  Explain that you are going to demonstrate a gambling hustle.

Show the cards and then let the spectator shuffle them. When the cards are mixed so that neither of you know the order, ask him to deal the four cards face down in a row across the table. I’ll give some basic patter so you can follow the plot.



‘Here is the bet. There are four cards, two reds and two blacks. And all you have to do is select two of them. If the two cards are the same colour, you win.’

‘It’s an even money proposition. Doesn’t matter whether you select black or red. You can select two red cards. Or two black cards. You only lose if you select one of each. Sound fair?’

The spectator agrees that it does sound fair.

‘It’s not fair at all,’ you say. ‘And I’ll show you why.’

Ask the spectator to turn one of the cards over. He does. Then say, ‘Now all you have to do is turn another card over and if the colour matches, you win. Which card would you like?’

Ask him to point to one of the three remaining face-down cards. Because the cards are marked you know whether he has pointed to a card of the same colour. If he hasn’t, ask him to turn the card over. It doesn’t match and he’s lost, just as you predicted.

He will lose two times out of three. This is a mathematical hustle. Using red and black cards to explain probability goes back hundreds of years but a significant date in magic history was December 1970 when Martin Gardner explained the swindle in his Scientific American column. Which is why this source is often given when trying to date the scam. For example, Gardner gets the credit in The Red-Black Swindle described in Karl Fulves’ The Big Book of Magic Tricks (1977).

If the player loses, you can offer to play again and this time you explain that athis isn’t actually a 50/50 bet. Once he has turned over a card he has nailed his colour to the mast. For example, if he turned over red, there are three cards left face-down on the table but two of them are black. The odds are against him.

But let’s assume that things don’t go your way and the spectator is pointing to a card that matches the colour of his first choice. At this point you’d prefer he changes his mind. So you now explain the swindle to him. And ask whether he would now like to change his mind. He can change his mind in one of two ways. He can point to another card. Or he can turn his original card face-down and pick another. Either way by laying out the real odds and offering additional options you are trying to psychologically force him into a losing situation. Think how Chan Canasta might handle it.

If he changes, wonderful. Turn the card over and reveal that he lost.

If he doesn’t change his mind, congratulate him on his intuition, ‘You are really good at this. No one ever beat this hustle before. I think you are ready for the big time.’

What is that? I hear you ask.

CHECK PAYER
Well, you have several options and, interestingly, for one of them we travel back in time long before Martin Gardner wrote his column. In The Conjurors’ Magazine for April 1946 Walter Gibson suggests a similar proposition bet, Check Payer, this time played with seven cards, five reds and two blacks.

Take three more red spot cards from the deck and add them to the four already in play. Lay the cards face-up on the table as you explain how the odds have increased in the spectator’s favour.  The game is to pick out three cards in a row. But look how the odds favour him.



‘On the first try you have five reds to two blacks. That’s 2.5 -1 in your favour.’

Pick up one of the red cards.

‘On the second try there are four red and two black cards. That’s 2-1 in your favour.’

Pick up another red card.

‘On the third try there are still three reds to two blacks. That’s a 3-2 edge for you. Looks fair right?

He says it does. And you tell him he’s wrong and you’ll explain why.

Shuffle the cards and then lay them out in a face-down row. The odds of him choosing three red cards in a row are 2.5 -1 against him. Walter Gibson says he ran the idea past Royal Vale Heath who wrote Mathemagic. Heath said that in two-hundred and ten tries there were only sixty possibilities of the spectator picking out three red cards. I have no idea how or why he arrived at those numbers.




Let the spectator choose cards by first pointing to them and then turning them over. The cards are marked so you know how well his choices are going and are able to use a bit of psychology and double-talk to get him to change his mind along the way.

Nick Trost described this routine as the Seven Card Wager in the September 1967 issue of The New Tops.  He doesn’t mention it but I imagine he might have read Walter Gibson’s article.

THE TIC TAC TOE BET
In the December 1965 issue of M.U.M magazine there is a description of a performance by Al Thatcher that took place at the U.F. Grant Assembly of the S.A.M in Columbus Ohio.

Al Thatcher began his routine of ‘Gambler’s Odds’ with two red cards and two black cards. He points out that the odds are even and presumably proceeds with a demonstration similar to that Martin Gardner later described in Scientific American magazine.

Thatcher then added three more black cards to arrive at the situation in Gibson’s Check Payer. Here the spectator shuffles the cards and then deals them into a face-down row.  The bet was that the spectator couldn’t turn up three black cards without turning a red card first.

Al won the bet and than added two more black cards and a new game. He arranged the nine cards into a 3 x 3 matrix, all cards face down. Al challenged the spectator to turn over three black cards before he hit a red card. It was a bet that Al won.

This betting matrix really piqued my interest and for a while I thought it was unpublished. But then I discovered that Nick Trost had put it in print.

You’ll find it in Gambling Tricks with Cards – Part 2 (circa 1975). Trost doesn’t credit Al Thatcher. They were acquainted. But the three stages of the bet are described, the finale with nine cards being titled the Tic Tac Toe Bet.

Let’s think about this with the cards we started with. In our version we’d add two more red cards. Now we have seven red cards and our two corner-marked black cards.

The challenge is for the spectator to turn over three red cards. However, he can only turn over cards that are in a row, column or diagonal.



I don’t know if Al Thatcher controlled the position of the black cards in his version and Trost doesn’t mention the idea. But it gives you are considerable advantage if you position the two black cards, one at a corner and one in the centre.



There are eight possible lines in the matrix but if you put the black cards at the centre and corner that leaves only two winning lines for the spectator. Add that to any psychological persuasion you might bring to bear and it’s a good bet for you.

If you have a group of spectators, then one way of overturning a correct decision is to give someone else the option of changing a card. Playing one player’s choices against another can also add to the entertainment value.

Another interesting aspect of Thatcher’s routine is that he was performing it in 1965, five years before Martin Gardner published his article in Scientific American and ten years before Nick Trost put it in print.

THE KICKER
Trost returned to the theme of the red black bet when he published his Seven Card Wager with a Kicker in the March 1971 issue of The New Tops. This is a magical version of the hustle in which the spectator loses repeatedly and then all the cards in the packet change to black cards. This is a good idea but Trost’s solution involves duplicate cards and false counts. An easier and better solution might be to secretly swap the packet of cards entirely for one in which every card is black.

Assuming that’s done the spectator gets unlucky by picking out a black card on his first choice. Feeling generous you say, ‘Well, we’ll consider it a win if you pick out two red cards.’ He tries again and picks out another black card. At this point he has lost the wager. But you offer him a third chance saying, ‘Okay, if you pick out an even value red card we’ll consider it a win.’ To his surprise he picks out another black card. Finish by turning over the remaining cards to reveal that every card is black. End of trick.

ANOTHER KICKER
Here is a different way of adding a kicker to the bet that makes use of the corner-marked black cards.

The deck must be set up with the red cards on top of the black cards. Go through the entire routine starting with the Red Black Proposition Bet, then the Seven Card Wager and then Tic Tac Toe Bet.

Pick up the cards from the table and replace them in the deck as follows. Insert one of the black cards into the lower portion of the deck. Let’s assume it’s the 8C. Insert the rest of the cards, including the 9S, into the upper portion of the deck. Then give the deck a false shuffle that retains the order or at least the separation between the upper half of the deck and the lower half.

Table the deck and offer the spectator one last bet. First ask him to cut off a portion of cards. You want him to cut a little less than half the deck but enough so it includes your corner-marked black card. If he cuts too few half him deal off a few more. You want the largest packet you can get. This packet will consist of all red cards except for one marked black card.

Put the rest of the deck away and, if you think the spectator can shuffle the cards, have him mix them otherwise do it yourself. Then take the packet and spread it face-down across the table.

‘Here is the bet. A challenge for both of us. All you have to do is pick out a red card. And all I have to do is pick out a black card. 50/50 odds for both of us. Let’s see how we do.’

The reality is that all the cards in the spread but one are red. Let the spectator make his choice first. If by chance he picks the black card, make the most of it. Turn the spread over and reveal that all the rest of the cards are red. ‘You just never seem to get a break. That’s my card.’

Most of the time he will take a red card. Don’t turn that card over for the moment. Instead, you choose a card from the spread, picking out the corner-marked black card.

‘Let’s see how I did.’

Turn over your card to reveal it’s a black card.

‘And now you.’

The spectator turns over his red card.

You then say, ‘I guess we’re both winners. Although to be fair, I think you had it easy.’

Turn over all the cards in the spread and show that they are all red.



NOTES
I think there’s a lot of fun to be had with the red black proposition bet. I personally don’t like the idea of playing it as a gotcha against the spectator. I’d rather explain it as the mathematical game it is. But Tamariz has a wonderful presentation in which he pitches one spectator against another in a game of Three Card Monte. I think it’d be possible to do something similar with the red black proposition bet. That way you’re not the one showing off.

There’s another interesting version of the bet in the June 1984 issue of The New Tops. It is in John Sherwood’s Lost in the Forest column. He credits Nick Trost’s Seven Card Wager with the inspiration. In Sherwood’s version five men and two women are asked to stand in a circle. A blindfolded volunteer stands at the centre of the circle. The challenge is for him to point to three men in a row. If he points to a man, that man leaves the circle. If he points to a woman, that woman gives him a kiss. Since there are more men than women he is convinced by the performer that he can eliminate the men from the game and if he misses he’ll get a kiss. It’s an interesting premise. There’s no kicker but it would be very tempting to rearrange that circle of people once the spectator has his blindfold on.

Finally, I recommend you take a look at Al Thatcher’s card magic. He has many wonderful ideas and routines in print. Thoroughly practical and clever card magic. There is also a book available that contains 73 of Al Thatcher’s tricks and 13 contributed by his friends:

Al Thatcher – After Hours Card Magic. Below is an Amazon Affiliate link for the Kindle edition of the book.


NOTE ON PROBABILITY FOR CHECK PAYER
In Check Payer I said I didn't understand how Royal Vale Heath arrived at the calculation that in 210 tries the spectator would only pick three red cards in a row in 60 of them. Well, Alain Gesbert emailed the following which makes the calculations clear:

The three games have the following number of red cards in them

1: 5 red cards among 7 cards
2: 4 red cards among 6 cards
3: 3 red cards among 5 cards

To calculate the probability of the spectator winning the bet you multiply the three ratios:

5/7 x 4/6 x 3/5 = 60/210

Thank you Alain!

The Trick That Fooled Einstein

-->
The Trick That Fooled Einstein is associated with magician and mentalist Al Koran.  He marketed it as Jackpot Coins. The basic effect is that the performer and spectator grab a handful of coins from a bowl of cash on the table. The magician then makes three statements about the number of coins they hold:

I will take the same number of coins as you

I will take 6 more than you

And I will have enough left over to make yours 15

Both parties count their coins and the magician’s statements are proved true. The trick can be repeated. The trick was originally performed with cards but Al Koran adapted it to use with coins and there have been lots of variations of it over the years. But to many it remains The Trick That Fooled Einstein because that’s the name given to it in Al Koran’s Lecture Notes (1972).  It was here that Koran said:

“While playing at the Savoy, I finished my act, and the manager said someone asked me to join them at their table. It was Albert Einstein, the mathematical genius. He leaned over to me, very personally, and asked: “Where in the world did you get those extra coins…did they come from your sleeve?”

I said, “No, it’s simple, a child can do it.” I did it at his table and fooled him again. I then told him “It’s not the numbers – it’s the words that fooled you.”

In 2005 Richard Wiseman emailed to ask if I knew where and when this trick was performed for Albert Einstein. It was the one hundredth anniversary of the year Einstein wrote three of his most notable papers on physics and seemed a good time to examine the story behind the trick that fooled such a brilliant man.

Richard had contacted the Albert Einstein Archives in Jerusalem but they could find no note of Einstein meeting Koran or being baffled by his trick. While Koran loved to bill himself as The Man Who Fooled Einstein perhaps Einstein wasn’t quite so keen to be known as The Man Who Was Fooled by Al Koran.

I thought that such a memorable occasion might be mentioned in Koran’s best-selling self-help book Bring Out The Magic In Your Mind (1964) and sure enough it is, on page 169. There is an extract from The Bulletin, presumably some kind of PR release, on which Koran makes a comment:

'…But if you’ve seen Al work on TV or the stage and been completely puzzled, don’t worry too much. No less a person than the late Professor Einstein failed to find out how it’s done.’

The professor was fascinated by a demonstration I gave him in London.

When Richard Wiseman checked out Einstein’s travels to England he discovered that he only visited twice: in 1931 and 1933. Both were trips to Oxford although it’s possible he passed through London. But Al Koran would have been nineteen years old and plain Edward Doe at that time, more likely to be cutting hair (he was a barber at the Ritz Hotel) than performing at The Savoy. The meeting with Einstein wasn’t Koran’s only extraordinary encounter with celebrity. In one publicity sheet from the 1970s he is described as being the son of the medium Helen Duncan.

I don’t know how long Koran had been performing Jackpot Coins but magicians saw it at the Annual Festival of Magic in 1956 (Magic Circular, Nov 1956).  That’s a year after Einstein died. The trick was later sold to magicians and first advertised in the March 1960 issue of The Gen.

Koran performed the routine on television several times. In The Gen (May 1960) Harry Stanley talks about a BBC Television performance on 20th April in which Koran introduced the trick as “trickery with words.” Interestingly enough that’s how Koran described it in his fictitious encounter with Einstein, saying, “It’s not the numbers that fooled you – it’s the words.”

This might be a point worth noting because the trick is not without suspicion. If you couch it as “trickery with words” you’re accepting that this is more of an interesting curiosity than straight piece of mind reading. Today, if you present it as the trick that Al Koran used to fool Einstein (much as Out of this World is the trick Harry Green fooled Winston Churchill with), then you have yourself a nice story for what is essentially a mathematical puzzle.

A NOVEL CARD EFFECT

Jackpot Coins has its origins in an old card effect that will be familiar to many. In this trick the performer and spectator both cut packets of cards and count them. The performer then makes a statement along the lines of, ‘I have as many cards as you plus three more and enough to make yours up to fifteen.” It’s a mathematical sounding trick that makes a good bar bet.

It's a good trick to perform across a table. Both you and the spectator can count their cards below the table. This prevents you counting each other's cards but also facilitates some of the trickery I'll describe later.

Al Koran’s Lecture Notes talked in terms of the number of coins but in his performances he actually talked about the amount of money. A spectator did not hold 15 pennies. She held one shilling and three pence (old English money). If you used cents and the spectator held 120 of them you would say she had one dollar and twenty cents. Not realising how Al Koran originally performed Jackpot Coins Jon Racherbaumer unknowingly reinvented it when he described his Correct Change routine in At The Card Table (1984).

Koran’s Lecture Notes credit the idea to a card routine called A Matter of Debit and Credit (Greater Magic, 1938). No originator is named there in connection with the trick. Later Jack Avis contributed a note to Martin Breese’s The Magic of Al Koran (1983) tracing the trick to Paul Stadelmen’s booklet Sandu Writes Again (1934). But again Stadelmen doesn’t claim the trick as his. He simply says that it’s an old trick.

I’ve found an earlier reference in The Magic World (November 1920). It contains a trick contributed by Howard L. Grant (Howard the Great) called A Novel Card Effect. Here it says, “While it is by no means new, it has never appeared in print.” As to who Howard L Grant was, well, that seems to be another mystery. Here is Howard L Grant’s original description of the effect as published in The Magic World magazine:
 

A neat little conception, notable for its simplicity, is the following. While it is by no means new, it has never appeared in print; and as it completely bewilders the unsophisticated observer, I know it will be appreciated.



A spectator is requested to take a number of cards from the pack. The magician also removes a bunch of cards, making sure that he has more than the spectator. The spectator is told to secretly count his cards, the magician doing  the same with his. Then, for example, the performer says: " I have as many cards as you, three more, and enough to make you twenty-four." The spectator says that he has fifteen cards. "Very well," remarks the performer, and he counts off fifteen cards from his heap, three more, and then counts the remaining cards, which prove to be nine, making the total twenty-four.



The secret is absurdly simple. When the performer counts his pile, he disregards a small number of cards, being sure however, that those remaining are still more than those held by spectator. Then we will suppose, as In the aforementioned example, he has twenty-four cards left, and he has disregarded three, making a total of twenty-seven cards. He then proceeds as above and the result is a completely baffled spectator.



This is a rather difficult feat to explain in print, but if the reader will experiment, following the above directions closely, he will find that it works identically as stated. In addition it is one of the few effects that will stand repetition, the magician being careful to change the number of cards in his discard each time.

THE REPEAT
As Howard Grant pointed out the trick can be repeated as long as you vary the numbers. When Paul Stadelman republished the trick, So Simple, in The Sphinx (Vol 48, No 5, July 1949), he mentioned an idea of Ralph Hull’s. This enables the performer to genuinely tell the spectator exactly how many cards he has in his packet. Here is the Hull repeat described by Paul Stadelman and entitled Still Simpler:

As a follow-up for “So Simple,” start off by offering to “explain” how it works. The apparent explanation seems so reasonable as you proceed with it, and casually mention that since you knew the number of cards they cut off (and mention the number), you simply took the difference between that number and the number you took and fifty-two and then knew the number of cards left on the table.



Someone is bound to ask how you knew how many cards were cut off before the spectator announced it. At this point tell him that you are gifted with “third sight,” and tell him to count his cards again to see if you were right.



Do “So Simple” again, as an example. This time the spectator cuts ten cards and you take fifteen. At the end of the trick, calculate mentally that ten plus fifteen equals twenty-five and throw them back on top of the deck, but note the bottom card of the packet of twenty-five, which we will assume is the ace of hearts.



Have the spectator cut off another bunch of cards, “To prove that I know how many you take,” let us say he takes seven. Now you cut off a bunch, but be sure you cut past the twenty-fifth card. For example, you took twenty-eight. As he counts his cards, you begin to count yours face up but what you actually do is pass them from hand to hand until you come to the ace of hearts. Call that card one mentally and count the cards from then on and you will find you have eighteen cards, which you subtract from twenty-five. This tells you he cut seven, as the ace was originally twenty-five cards deep.



Now for your explanation. “You see the way I do this trick is that I first count my cards. In this case I happen to have thirty. (You mention any number here, for you really do not know how many cards you have, due to the fact that you only counted part of them, just guess at what you think you have.) Since I know I have thirthy, and I know you have seven, then I know I have as many as you and twenty-three more.” Then make the remark about “third sight.”



Now proceed again with the original method of “So Simple” and you will have them believing you each time.



The idea for this second version was suggested by the late R. W. Hull, who was the inventor of many clever card tricks.

ADDITION TO STILL SIMPLER

It requires considerable mental work but if you count the cards in your hands you can also know the number of cards not only in the spectator’s packet but also the packet left on the table. There are various ways of making this calculation. One is to take the position of the key card from the top of the deck and deduct it from 52 (the number of cards in play).

If the key card is 20th then 52 – 20 = 32. That’s the number of cards below the key card and you memorise this key number.

When you spread through the cards in your packet, mentally you count the number of cards that are above your key card starting at 32 (your new key number), counting backwards: 32, 32, 30, 29 etc. When you hit the key card the number you reach in your counting is the number of cards in the tabled packet.

Now continue counting, starting on your key card (20), and again counting backwards: 20, 19, 18, 17 etc. When you run out of cards you know the next number represents the number of cards the spectator holds. Sounds complicated on paper. Makes sense when you try it. But you still need to keep your wits about you to pull off.

One way to ease the task is to place your key card at an easy to remember and predetermined number like 20. You can do this just by moving a few cards from the top to bottom of the deck, or vice versa, while setting up your key. That way your key numbers are always the same, 20 and 32. The only new item you are memorising is the key card itself.

THE WORM TURNS

Ed Marlo had a wonderful bit of business that turned the tables on anyone who performed the  “I have as many cards as you” routine. He described it in Ibidem (No 17, July 1959). When someone says, “I have as many cards as you, four more, and enough to make your cards seventeen” you are able to immediately say, “I can do better than that. I can tell you exactly how many cards you have. You have twenty-one.” And you'll be right.

All you do is total the two numbers they give you. As Marlo says, it really takes people off guard.

Ed Marlo dated his note November 9, 1958, which is just a year or two after Martin Gardner’s Mathematics, Magic and Mystery was published. Gardner’s book describes the trick under the title The Estimated Cut. It’s possible Gardner’s book brought the trick back into popularity. As part of the book’s promotion Estimated Cut was reprinted in The Magic Wand (Vol 46, No 254).


THE TRICK THAT BAFFLED KORAN

John Bannon came up with an unexpected finale for the routine in his Einstein Overkill (Bullets After Dark DVD, 2009) in which four aces are produced. It’s an odd idea but an interesting one and it occurs to me that if you tell the story of the Trick That Fooled Einstein then you might add an equally fictitious finale in which the great Einstein fools Koran.

The version described here is different from Bannon’s original. Now the beauty of the original card trick is that it can be done impromptu and with a shuffled deck. However, to produce four aces you need to set the cards up.

As mentioned earlier the trick is performed across the table with the assisting spectator seated on the opposite side. The aces need to be positioned as follows: one on top of the deck. Two together somewhere in the middle. And one on the face of the deck. A smart culler could do this relatively quickly. But you could also do it quite more simply as you pick up the cards and talk to the spectators about how Einstein, having been baffled by Koran, examined the cards closely for marks.

Now you do have a couple of advantages. The first is that the deck is already in three packets. Yours, the spectator’s and what’s left. That gives you a lot of opportunities to pick up each packet separately, casually spread through them, secretly find the aces and put them into the right positions as you assemble the deck.

The other advantage is that you already had a chance to look through your cards when you counted them. You’ll know if it contains aces and you can arrange them accordingly.

With the aces in position tell the spectators that Einstein asked to try to the trick himself. Pick out someone else to play the part of Koran. Now repeat the first part of the trick. The spectator cuts some cards but don’t have him count them yet.

You now cut a packet of cards ensuring that you cut deeper than the two adjacent aces which are in the middle of the deck. Hold the cards face-up under the table and count them as before. You also spot the two aces and cut the packet, bringing one to the top and one to the face. Turn the packet face-down and bring it from under the table.

You know how many cards are in your packet and can now make your three statements about how many cards you have.

When you’ve done that ask the spectator to count his cards one at a time face-down onto the table. This will place an ace at the face of his packet.

As per the original routine you now count exactly the same number of cards into a separate packet on the table. “To Koran’s amazement Einstein was right. He had exactly the same number of cards.”

Three aces are already in position on the table. But there is one ace at the face of the packet in your hand. There are various ways of getting it into position for the finale.

A simple way is to pass the packet to the right hand and fan it. Now when you deal the “and three more,” or whatever number you named to the table, you take cards from the bottom of the spread not the top. It’s reasonably natural to do this. Deal these cards into a packet on the table. The ace is now the face card of that packet.

Alternatively do a bottom deal as you count the cards to the table. It’s not that difficult. No one is even looking for it.

Finish the last of your statements, “and enough to make your packet up to twelve” or whatever. And deal these cards onto the spectator’s packet.

You are now set for the finale. There are four packets of cards face-down on the table. And at the face of each packet is an ace.

“Koran was amazed. How did you do that?” Finish with a little misquote from Einstein. “I do not believe that God plays dice. But sometimes he gets lucky with cards.”

Turn over the packets to reveal the four aces.

HISTORY NOTES

Michael Weber published a very clever presentation for Jackpot Coins called Picking on Rainman. The trick uses cocktail sticks/toothpicks instead of coins which are more practical props for impromptu work. It further develops the “trickery with words” of the Koran routine too. You’ll find it in M.U.M magazine (Vol 98, No 8, January 2009).

Earlier Karl Fulves had used matchsticks in his version of the trick. See Matching Matches in Self-Working Table Magic (1981) Bill Mullins emailed and advised that he had tracked down an even earlier version the trick to Will Blyth's book Match-Stick Magic (1921). The publication date also makes it one of the earliest references to this effect. Bill has posted his quest for the origin of The Trick That Fooled Einstein on the Genii Forum and you can read it here.

The Will Blyth trick is called Matchstick Divination and you can download a copy of Match-Stick Magic from Lybrary.com.

Al Koran’s Bring Out The Magic In Your Mind must be one of the most successful self-help books ever written perhaps in part due to the mystical sounding name of its author. You can find it all over the world. Far from getting rich on this it is more than likely that the book was ghost-written. There is a claim in the Review section of the Amazon site that the author was June Hope Kynaston, who also authored The Mind That Works Miracles, a book that seems as hard to find as Koran’s book is ubiquitous.

CARD NOTES

I've found a few more references that might be of interest. The first is Harry Franke's handling of The Trick That Fooled Einstein. See Bill Miesel's Precursor magazine (LV, August 1996).

The second is also in Precursor (LXXIX, August 2001). It is Al Thatcher's Climax Estimation which produces four of a kind at the end of the "as many as you" routine.

In Precursor editor Bill Miesel mentions that he learned the trick from Scarne on Card Tricks (1950). Scarne calls the trick The Quickie Card Trick. Given the 1950 publication date it is interesting to wonder whether Al Koran read this book and it inspired Jackpot Coins because not only is The Quickie Card Trick there but also a story about a magician and Einstein. See Einstein and the Magician in which the great scientist baffles a conjuror.
