Bob Voulgaris had become one of the most successful sports gamblers in the world when, in 2004, he started to lose. It wasn’t just a streak of bad luck, a series of randomly unfavorable outcomes that could last only so long. His edge, he realized, was gone.
He had begun betting on sports in the late 1990s, and within five years, before he had reached his 30th birthday, Voulgaris had accumulated a fortune. He says he routinely wagered a million dollars in a single day of NBA games. He considered his mean to be an unholy winning percentage that approached 70 percent. A man of no fixed address, he dated models and traveled the world. He was also an accomplished poker player, buying his way into high-stakes games from Las Vegas to Macau. He was essentially leading the fantasy life of your basic under-35 North American male.
A specialist in the NBA, his sports gambling success was almost completely the result of a kind of studied perspicacity, born of a talent for pattern recognition and the stamina to watch uncountable hours of televised basketball. In betting parlance, the man could suss out an edge -- and in 2002, he discovered one that would line his pockets for years. It all had to do with how most bookmakers set their halftime totals, the predicted number of points scored in each half of the game. Each half, of course, is its own discrete period of play, and the fourth quarters of close games can end in elongated foul-clogged stretches of free throws, timeouts, fast play and, hence, a burst of scoring. But incredibly, bookmakers at the time didn’t account for this fact; they simply arrived at a total for the full game and cut that figure roughly down the middle, assigning some 50 percent of the points to the first half and 50 percent to the second.
