Dealer Button

What it means

The dealer button is a physical marker - usually a white plastic disc - that designates which player acts as the dealer for the current hand. In casino and online poker, where a professional dealer handles the cards, the button determines the order of play and which positions post the blinds. The player “on the button” has the most advantageous position at the table.

How it works at the table

The button moves clockwise after each hand completes. The player immediately left of the button posts the small blind, and the next player posts the big blind. Action begins with the player left of the big blind (under the gun) and continues clockwise.

Consider this example: In a 9-handed $1/$2 game, Player A has the button. Player B (small blind) posts $1, Player C (big blind) posts $2. After cards are dealt, Player D acts first preflop. On all postflop streets, Players B and C act before Player A, giving the button position maximum information before making decisions. If Player A raises to $8 with K♠ Q♦ and only Player C calls, Player C must act first on the flop of J♠ T♣ 5♦.

Strategic context

Button position offers two critical advantages: you act last on all postflop streets and can play the widest range of starting hands profitably. Professional players often open-raise 40-50% of hands from the button when action folds to them. This positional advantage allows for better pot control, more accurate hand reading, and increased bluffing opportunities. The button wins more pots than any other position.

Common mistakes

Players frequently waste their positional advantage by playing too passively on the button - just calling instead of raising with decent hands. Many also fail to defend their button against steal attempts from the cutoff, folding too often when they should be 3-betting or calling wider. Another error is not adjusting their button strategy based on the specific players in the blinds; tight blinds should face more aggression than loose, aggressive ones.

The button works in conjunction with the blind structure to create the fundamental dynamics of poker. Understanding button play is essential for any serious player developing their positional strategy. The cutoff (seat right of the button) serves as a secondary power position, while the blinds represent forced investments that must be defended appropriately.
