James Grosjean’s early life is little known, but his academic background reveals a sharp analytical mind. He studied at the University of Chicago, first in the Department of Economics and later in Mathematics, where he developed the skills to make him one of history's most respected advantage players.
Grosjean’s career in gambling began while he was still a graduate student. After spotting his first dealer hole card in a Three Card Poker game, he realized the potential for exploiting such opportunities mathematically. His deep analysis of hole carding and other advantage techniques led to his first book, Beyond Counting: Exploiting Casino Games from Blackjack to Video Poker (2000), which became a must-read for professional gamblers.
In 2007, he released an expanded edition, Exhibit CAA: Beyond Counting, a rare and highly sought-after book that sells for thousands of dollars when a copy surfaces.
Beyond writing, Grosjean competed in televised blackjack tournaments, including the Ultimate Blackjack Tour on CBS. He also collaborated with Keith Taft, a fellow Blackjack Hall of Famer, to develop a legal blackjack computer.
