All-in:
Committing all remaining chips to the current pot. Once a player goes all-in, they cannot act further in that hand regardless of subsequent betting.
Ante:
A mandatory bet placed by players before cards are dealt, typically in stud games and some casino poker variants. Antes ensure the pot has initial value.
Blind:
Forced bets made by specific positions before seeing hole cards, primarily in Texas Hold'em. Small blind and big blind drive action and pot value.
Community Cards:
Shared cards available to all players, used in Texas Hold'em and Omaha. Players combine these with hole cards to create final hands.
Check:
Passing the action to the next player without betting when no bet has been made. Checking allows players to remain in the hand without committing additional chips.
Fold:
Surrendering the hand and forfeiting all claims to the pot. Folding occurs when a player decides their hand cannot win or the risk-reward is unfavorable.
Hole Cards:
Private cards dealt face-down to individual players. In Texas Hold'em, each player receives two hole cards. In Omaha, four hole cards are dealt.
Pot Odds:
The mathematical ratio of current pot size to required bet. Comparing pot odds to hand equity determines whether calls represent profitable long-term decisions.
Position:
A player's seat relative to the button and blinds. Late position provides significant advantages through increased information about opponent actions before decision-making.
Raise:
Increasing a previous bet or call. Raising indicates hand strength and controls pot size and competition.
