What is ‘Dealer Button?’
The dealer button is a disc, usually made of white plastic, with the word “DEALER” written on it that rotates around the table and determines which player will act last on all post-flop betting rounds.
‘Dealer Button’ Explained
In all poker games that use rotating position, which includes flop games like hold’em and Omaha variants but extends to other games as well, a dealer button is used to denote the position of the players for the hand. The dealer always starts dealing with the player to the immediate left of the dealer button (which is also the small blind) and the player with the dealer button always receives the final card before a hand begins. At the end of each hand, the dealer button moves, and the player who was in the small blind the previous hand has the dealer button for the upcoming one.
Having the dealer button is a tremendous advantage because it gives the player in possession of the button last action on all post-flop betting rounds. Having last action enables the player with the button to make more informed decisions, decisions, and in poker, better decisions make for higher profits. The positional advantage that comes with having the dealer button makes it profitable to play a wide range of hands in position.
The dealer button is often referred to simply as “the button,” and there are some regional variations on the name as well. For example, in Canada, the dealer button is commonly referred to as “the puck.”
