Three cards of the same rank, and two cards of a different, matching rank.
In the event of a tie: Highest three matching cards wins the pot. In community card games where players have the same three matching cards, the highest value of the two matching cards wins.

Five cards of the same suit.
In the event of a tie: The player holding the highest ranked card wins. If necessary, the second-highest, third-highest, fourth-highest, and fifth-highest cards can be used to break the tie. If all five cards are the same ranks, the pot is split. The suit itself is never used to break a tie in poker.
