The term "sharp gambler" is typically used in the context of sports betting. However, the term may be used to describe a skilled casino player who is able to gain an advantage over the house and make consistent profits over time.Advantage players in casinos often rely on a deep understanding of the game they're playing and use strategies and techniques to gain an edge over the casino. For example, a skilled blackjack player may use card counting techniques to keep track of the cards that have been dealt and adjust their bets accordingly, while a video poker player may use optimal strategy to reduce the house edge and increase their chances of winning.It's worth noting that while sharp players may be able to gain an edge over the casino, casinos typically have measures in place to identify and discourage advantage play.
