Overview

Calculated Bets describes a gambling system that works. Steven Skiena, a jai-alai enthusiast and computer scientist, documents how he used computer simulations and modeling techniques to predict the outcome of jai-alai matches and increased his initial stake by 544% in one year. Skiena demonstrates how his jai-alai system functions like a stock trading system, and includes examples of how gambling and mathematics interact in program trading systems, how mathematical models are used in political polling, and what the future holds for Internet gambling. With humor and enthusiasm, Skiena explains computer predictions used in business, sports, and politics, and the difference between correlation and causation. An unusual presentation of how mathematical models are designed, built, and validated, Calculated Bets also includes a list of modeling projects with online data sources. Steven Skiena, Associate Professor of Computer Science at SUNY Stony Brook, is the author of The Algorithm Design Manual (Springer-Verlag, 1997) and the EDUCOM award-winning Computational Discrete Mathematics. He is the recipient of the ONR Young Investigator's Award and the Chancellor's Award for Excellence in Teaching at Stony Brook. His research interests include discrete mathematics and its applications, particularly the design of graph, string, and geometric algorithms.

Chapter One: The Making of a Gambler

My interest in jai alai began during my parents' annual escape from the cold of a New Jersey winter to the promised land of Florida. They stuffed the kids into a Ford station wagon and drove a thousand miles in 2 days each way. Florida held many attractions for a kid: the sun and the beach, Disney World, Grampa, Aunt Fanny, and Uncle Sam. But the biggest draw came to be the one night each trip when we went to a fronton, or jai alai stadium, and watched them play.

Mom was the biggest jai alai fan in the family and the real motivation behind our excursions. We loaded up the station wagon and drove to the Dania Jai-Alai fronton located midway between Miami and Fort Lauderdale. In the interests of preserving capital for later investment, my father carefully avoided the valet parking in favor of the do-it-yourself lot. We followed a trail of palm trees past the cashiers' windows into the fronton.

Walking into the fronton was an exciting experience. The playing court sat in a vast open space, three stories tall, surrounded by several tiers of stadium seating. To my eyes, at least, this was big-league, big-time sport. Particularly "cool" was the sign saying that no minors would be admitted without a parent. This was a very big deal when I was only 12 years old.

We followed the usher who led us to our seats. The first game had already started. We watched as the server spun like a top and hurled the goathide sphere to the green granite wall, where it rocketed off with a satisfying thunk. His opponent climbed up the sidewall to catch the ball in his basket, or cesta, and then - with one smooth motion - slung it back to whence it came. The crowd alternated between ooh and ah as the players caught and released the ball. The players barked orders to their partners in a foreign tongue, positioning each other across the almost football-field-sized court. Thunk, thunk, thunk went the volley until a well-placed ball finally eluded its defender.

After each point, the losing side would creep off the court in shame replaced by another team from the queue. The action would then resume... thunk, thunk, thunk . . . .

You have to visit a jai alai fronton to really appreciate the sights and sounds of the crowd. Most of the spectators, at least the most vocal ones, don't seem terribly knowledgeable about the players or game. Indeed, many are tourists or retired people who wouldnt recognize a pelotari, or jai alai player, if they woke up in bed with one. There is only one player they are interested in: themselves. The spectators have money riding on each and every point and are primarily concerned about the performance of their investment:

"You stink, red."
"Drop it, number 5."
"Just one more point, Laxi - uh, whatever your name is."

Occasionally a more knowledgeable voice, usually with a Spanish accent, would salute a subtle play: "Chula! Chula!'.

The really neat thing about jai alai is that events happen in discrete steps instead of as a continuous flow, and thus the game is more like tennis than basketball or horse racing. After watching a few games, I began to get the hang of the scoring system. The pause between each point gives you time to think about how the game is shaping up and what the prospects for your bet currently are. Sometimes you can look ahead and figure out an exact sequence of events that will take you to victory. "Look, if 1 beats 5 on this point, then loses to 7, and then 4 wins its next two points, the game ends 4-2-1 and I win!"

With each point, the loyalties of the crowd change rapidly. A wonderful aspect of the jai alai scoring system is that the dynamics of the game can change almost instantaneously. In baseball, you can be 12 runs ahead, and thus giving up one run costs you absolutely nothing. This is not so in jai alai. No matter how far ahead you are, the loss of a single point can kill by forcing you to sit down to watch your opponent win the match. Suddenly a team given up for dead trots back on the court, and then it becomes a whole new game.

Fan loyalty is particularly fleeting because it is often the case that a bettor now needs to defeat the same player he or she was rooting for on the previous point.

"You stink, blue."
"Drop it, number 6."
"You're my main man, Sourball. I mean Sor-ze-ball."

After we got settled into our seats, my father gave me, the oldest of the three kids, a pair of rumpled one-dollar bills. It was enough for one bet over the course of the evening. "Use it wisely," he said.

But what did wisely mean? On his way into the fronton, my father had invested 50 cents on a Pepe's Green Card. Pepe's Green Card was a one-page tout sheet printed on green cardboard. I was much too young to catch any allusion to Pepe's immigration status in the title. For each of the games played that evening, Pepe predicted who would finish first, second, and third alongside a cryptic comment about each player such as "wants to win," "tough under pressure," or "in the money"

On the top of the card, in a box on the right-hand side, Pepe listed his single "best bet" for the evening. That night, Pepe liked a 4-2-1 trifecta in the sixth match.

My brothers and I studied this strange document carefully. We liked the idea of a tout sheet. It would help us spend our money wisely. As kids, we were used to being told what to do. Why should it be any different when we were gambling?

"Boy, this is great. Pepe must really know his stuff," I said.

My brother Len agreed. "You bet! We've got nothing but winners here."

"Dad, why do other people pick their own numbers when Pepe has all the winners here?" asked Rob, the youngest.

"Pepe, my pupik." came my parental voice of authority. "Pepe wouldn't know a winner if he stepped on one."

"Look, Pepe gives a best bet. A 4-2-1 trifecta in the sixth match. It can't possibly lose...."
