Two Pair Poker consists of two cards of the same rank, another two cards of some other rank that match each other but not the first pair, besides one card not of either rank.
It has two matched cards of the same rank, and three random and unrelated side cards. This is quite a common scenario to find it in every few games in Texas Holdem hand rankings or those of Omaha as well.
It can be simply any card that does not fall into any of the categories mentioned above. It is best used to break the deadlock and determine the winner in case of a tie, provided none of the aforementioned hand rankings are available. If the first cards are identical, the second card is taken into account. If they are also identical, then the next one and so on until the first superior card is found.
