Shark

In the context of casino games, a shark (or card shark) is a term used for players who are exceptionally good at the game. The term is often applied to professional and semi-pro gamblers, such as poker players and blackjack players who have mastered basic strategy and know how to count cards. Alternatively, this term can be used for a player who is cheating, such as a capper. 

How Do I Avoid Sharks?

There’s no way for you to avoid players who are good at playing a game. When it comes to protecting yourself from cheaters, this can be done by playing at a reputable casino or online venue. While cheating is still common in small, informal games, modern surveillance techniques allow casinos to ban cheaters and enter them into the black book quickly and efficiently.
