The goal of the project is to create a poker playing AI. But before I do that, I need to make a poker game! When I first posted this my intent was to be able to have the absolute strength of each hand be represented by a real number. However after getting into some of the link people have provided, I'm gonna get the probabilities going for the AI based on the hole cards and public cards. All I need now is to be able to determine the best hand from 7 cards. I was hoping to find some nice elegant solution, but now I'm just doin one of these...

bool hasPair(Hand hand);
bool hasTwoPair(Hand hand);
bool hasThree(Hand hand);

etc.
