Definition of full bring-in
When a player pays the bring-in, he will always have the option of raising to a full bet. The act of paying this bet is called "bringing it in" or "bringing in the pot". In Seven-card stud, to determine who will pay the bring-in, all players are dealt cards that are visible. The player with the worst card will be the bring-in. In case of a tie, the worst card will be determined by suit according to the following chart (from lowest to highest suit): clubs, diamonds, hearts, spades. So, if one player has the deuce of spades and another has the deuce of clubs, the player with the deuce of clubs is the bring-in.
