@WCDT had to bring this up because I ran into a table that didn't know the difference. Sets-- When you have a wired pair (Same 2 cards in your hand) and your card hits the board. Trips--is when you have 2 different cards in your hand (A-K) and the board has 2, of 1, of your cards (A-A-7-10). 2 people can have "TRIPS", but only one person, can have that "SET"!
