A sharp bettor is a seasoned and skilled player who approaches betting with a disciplined strategy, often relying on extensive research, statistical analysis, and a deep understanding of the sports or events they wager on. They typically focus on finding value in the betting lines and aim to exploit inefficiencies in the sportsbooks' odds. In contrast, a recreational bettor, often referred to as a "square," generally wagers for entertainment rather than profit, often based on personal biases, gut feelings, or popular trends without extensive research.
