The term “action card” generally refers to a community card that is dealt face up on the board and is likely to increase the amount of betting and wagering activity in a hand.
An action card is typically a card that completes a draw, creates a strong hand, or increases the likelihood that players will have a strong hand. For example, if a straight or flush draw is possible on the board and an action card is dealt that completes the draw, players may be more likely to bet or raise aggressively.
Action cards can also increase the number of possible hands that players can make, which can create more opportunities for betting and wagering. For example, if a low card is dealt on the board in a game like Texas Hold’em, it may create more opportunities for players to make two pairs, sets, or straights, which can lead to more action.
Overall, the term “action card” is often used to describe a card that is likely to increase the amount of betting and wagering activity in a hand, and which can potentially change the course of the hand.
