Card sharp

Imagine you are playing a game with cards, like Go Fish or Old Maid. A card sharp is someone who is really good at playing this game and can win a lot of times. They know how to shuffle and deal the cards in a sneaky way so that they can get the cards they want without anyone noticing. Sometimes they might even mark the cards so they can remember which ones are where. However, being a card sharp is not fair to the other players because they are cheating. It's like playing a game where one person has an unfair advantage and no one else can win. It's important to always play games fairly and have fun without cheating.
