6.19 Card Shark / Card Sharp

Slang — Player Classification

A “card shark” (historically “card sharp”) is an expert at card games, often with connotations of skill in cheating or manipulation. The term can refer to either a legitimate expert player or a cheater. In modern usage, “card shark” generally carries positive connotations of expertise, while “card sharp” has darker implications of dishonest skill. Casino surveillance teams are specifically trained to identify and monitor individuals suspected of being card sharps.

In practice

The distinction between a skilled card player and a card sharp cheater is a key surveillance function. Modern casinos employ sophisticated methods to detect sleight of hand, card marking, and other cheating techniques associated with card sharps.
