Open [Meaning] - MasterTerms.com

Open

A player is said to be "open" when they initiate the betting round by making the first bet or raise after the blinds have been posted. This action signals that they are willing to risk their chips and indicates confidence in their hand, prompting other players to decide whether to call, raise, or fold.

In a typical poker game, players take turns in a clockwise direction, starting from the player to the left of the big blind. When the action reaches a player who wants to enter the pot, they can either check (if no bets have been made) or make a bet, which is referred to as “opening the action.” By doing this, they establish a minimum amount that other players must call to continue in the hand.

Open Example

For example, if the big blind is $5 and a player decides to open by betting $15, all players must now decide whether to call the $15 bet, raise it, or fold their hands.
