Community card poker

Community card poker refers to a category of poker games utilizing shared cards. These cards, known as community cards, are dealt face up in the center of the table. Every player at the table shares these cards to build their hands. Each player also receives private cards called hole cards, which remain face down. To complete a hand, players must combine their private hole cards with the shared community cards. This set of shared cards is often called the board. The board may be arranged in a simple line or a special pattern.

In the most popular version, Texas hold 'em, the game follows a specific sequence of stages. First, each player receives two private hole cards, followed by a betting round. Next, three community cards are dealt face up to form the flop. This is followed by a second betting round. A fourth community card, called the turn, is then dealt, leading to a third betting round. Finally, the fifth community card, known as the river, is dealt before the last betting round.

To prevent cheating, players often "burn" a card by placing it in a discard pile before dealing the flop, turn, or river. This ensures no one can mark the top card of the deck.

At the showdown, players determine the winner by forming the best five-card hand possible. In Texas hold 'em, a player may use both, one, or even none of their hole cards. They simply choose the best combination from their two cards and the five board cards. This differs from Omaha hold 'em, which has much stricter requirements. In Omaha, players are dealt four hole cards. However, they must use exactly two of those hole cards and exactly three of the five community cards. This rule ensures that the private hand and the board must work together in a specific way.

Many variations of these games exist, often changing the deck or the number of cards dealt. Royal hold 'em uses a stripped deck, meaning several cards are removed. In this version, deuces through nines are taken out, leaving only tens through aces. Because the deck contains only 20 cards, a table can have a maximum of six players. Six-plus hold 'em, or short-deck hold 'em, is another variant where cards valued 2 through 5 are removed. These changes to the deck alter the mathematical odds, making certain hands much more common than in standard games.

Some games, like the Pineapple variations, involve players receiving more cards than they eventually keep. In Pineapple hold 'em, players are dealt three cards but must discard one. In Crazy Pineapple, the discard happens after the flop. There is also Tahoe, or "Lazy Pineapple," where players discard after the final betting round. In Manila, a game played with a 32-card stripped deck, players must use exactly two hole cards and three community cards. Because the deck is smaller in Manila, a flush actually ranks higher than a full house.

Betting structures and game positions also define the experience of community card poker. These are often considered positional games because the order of players affects strategy. For example, a betting round typically begins with the player to the dealer's left. When blinds are used, the first round starts with the player after the big blind. In home games, players often use antes to start the pot. Casinos, however, typically use blinds. Betting limits can also vary, including no limit, fixed limit, or pot limit games.

Some advanced versions allow for high-low split pots. In these games, the pot is divided between the best high hand and the best low hand. In Omaha high-low split, a player must qualify for a low hand by having a hand of 8-7-6-5-4 or lower. Aces can count as both high and low cards in these situations. This allows for the possibility of one player winning both halves of the pot. These complex rules turn community card poker into a game of deep strategy and mathematical calculation.
