The Truth About Rainman

The movie, Rainman, provided me with my first glimpse of card counting. In Rainman, Tom Cruise plays a slick, fast talking hustler, Charlie Babbit, and Dustin Hoffman, who steals the show, plays Charlie’s autistic savant brother, Raymond Babbit.  In a sub-plot of the movie, when Charlie realizes Raymond has a photographic memory and an incredible penchant for numbers, he hatches a plan to capitalize on Raymond’s abilities. This sets up a classic scene in Vegas in which the brothers try to strike it rich playing blackjack. Before I watched this scene, I knew nothing about card counting. I had never seen or read anything on the subject. As I rooted for the Babbit brothers, little did I know, one day I would become a card counter myself.

Years later, I watched Rainman for the second time with about seven of my MIT Blackjack teammates. We naturally took a special interest in the card counting portion of the movie. I watched Rainman in a very different light compared to the first time, but still, I loved it more the second time around. I did pick up on a number of flaws in the movie from a professional card counter’s perspective. I also found myself wondering what it would be like to have someone like Raymond on our team.

Before they arrive in Vegas, Charlie gives Raymond a primer on card counting which can be described as shoddy at best.

“When there’s lots of 10’s left, 10’s and picture cards, then it’s good for us.”  Hmmm, what about the aces. They’re kinda important too. 

“And you’re gonna bet one…. One if it’s bad. Two if it’s good. ”
This is not an effective betting strategy. A card counter needs to know not only when the count is favorable, but more important, how favorable it is.

“Now listen. Casinos have house rules. The first one is, they don’t like to lose. So you never, never show that you are counting cards. That is the cardinal sin, Ray.” I must admit. Charlie nails that one on the head.

When Charlie and Raymond glide down the escalator at Caesars Palace toward the casino floor in their dapper attire, it makes for one of  the most
memorable shots in the movie. Soon after they sit down, Raymond commits a different cardinal sin by hitting a hard 18, and busts with a queen.  The silver lining of Raymond’s blunder is his telling Charlie that there are lots of queens left.  Charlie’s eyes light up with this information and he then decides to go for it, doubling down on his 10 versus the dealer’s 4.  Charlie makes this play based on Raymond’s information, but he should have doubled down regardless. Doubling down on a 10 versus dealer 4 is simple basic strategy.  The number of queens left has no bearing on this decision. A perfect double down hand for the movie’s purposes would have been a player 10 versus dealer 10 (a hand most players don’t  double down on). Of course when Charlie doubles down he gets a queen and the dealer flips over another queen and then busts with a third queen.

Another thing that wasn’t right about this sequence is that knowing how many queens are left is not enough information to gain an advantage.  How about the 10’s, jack’s, king’s, and ace’s?  Not to mention the low cards (2, 3, 4, 5, 6).  The net difference between high cards and low cards divided by the number of decks remaining determines player advantage.  The queens are just a small piece of the puzzle. With the proper strategy and instruction, Raymond could be the ultimate card counting machine.  He could memorize a basic strategy chart in a matter of minutes. The running count and the true count would be a breeze, and anyone who can count 246 toothpicks in a flash from 10 feet away would find estimating the number of decks remaining in the shoe a snap. On the flip side, Raymond would face some challenges as far as fitting in the casino environment. In the movie, Charlie recognizes this which is why after he pawns his expensive watch for a gambling bankroll, he springs for a major makeover for Raymond and himself.  A nice suit along with new shoes and a fresh haircut go a long way toward making Raymond look like someone of consequence.

Even with their extremely limited betting scheme – one chip bad, two chips good, Charlie and Raymond hit a hot streak, winning more than $80,000 despite getting shorted a black chip on a double down payoff (you have to watch carefully).Their success prompts the floor people to call up to the eye in the sky. The conversation in the surveillance room is one of my favorite parts of the movie.

“What do you see? ”
“Well, he’s not catching the hole card, and he’s not past posting us.”
“I don’t see him using a computer.”
“No he’s not, but some thing’s not right.  You know there’s no one in the world that can count into a 6-deck shoe.”

The last line is my favorite. My teammates and I cracked up. I was impressed that the movie’s script mentioned hole card play and past posting (a cheating move in which  chips are added to a winning bet). These surveillance guys are well versed with hole card strategy and past posting, which most people have never even heard of, yet they believe no one in the world can count a 6-deck shoe?  That line, followed by the camera panning in on Raymond and his computer-like mind at work cement the legacy of “Rainman” and help perpetuate the myth that only geniuses can count cards.  Later on, the casino changes its mind. The director of security informs Charlie they are no longer welcome to play blackjack.  Their play was reviewed on tape and it was concluded that Charlie and Raymond did manage to pull off the amazing feat of counting down a 6-deck shoe.

For anyone who’s ever counted cards or even thought about counting cards, Rainman will forever be part of gambling lore. Even if you have no interest in blackjack, Rainman is a superb movie, winner of four Oscars, including best picture, actor, and director. The film captured my imagination as to how it would feel to beat the house, and years later, even with all its card counting peccadilloes, I had an even greater appreciation for Rainman. I guess it’s hard for me to take too much issue with a movie that portrays card counters as good guys and geniuses, no matter how much of an exaggeration the latter may be.
