Poker is a card game in which players bet money into a pot based on the strength of their hand. The best hand wins the pot.
There are a variety of variants of poker, but all share several essential characteristics. First, a player must make an ante (or blind bet) before the cards are dealt.
Once the antes are paid, the dealer deals the appropriate number of cards one at a time to each player. These cards may be face up or face down depending on the variant of the game.
The first round of betting follows, during which all players must decide to call (match) the last bet made by a previous player, or fold their hand. This action continues clockwise until everyone has either called or folded their hand.
Next, a player can draw replacement cards to replace those already in their hand. This is usually done during the betting round, but can be done at any point in the hand.
During the flop phase, the dealer deals three community cards to all players. These can be used by any player to form their strongest five-card hand.
Once the flop is complete, a third round of betting follows. This round also includes the addition of a fourth community card.
At the end of this round, a final betting phase occurs, during which all players must reveal their hands. This process may vary slightly between different variants of the game, but typically involves players taking turns clockwise around the table revealing their hands.
