Sportsbooks employ a variety of strategies to limit the action of sharp bettors, primarily to maintain their own profitability and balance their books. One common tactic is adjusting betting lines rapidly in response to sharp action, effectively reducing the value of the bets available to savvy players. They may also impose betting limits on specific markets identified as being popular with sharp bettors, capping the maximum amount a bettor can wager. Additionally, sportsbooks closely monitor betting patterns and player profiles, using sophisticated algorithms to identify accounts that consistently win or exploit line inefficiencies.
