Basically, poker is a group game played around a circular table. Each player has five cards and is attempting to create the best hand possible. The goal of the game is to make the best combination of cards by betting until all other players have dropped out. Various forms of poker are played with different numbers of players, but the rules are largely the same.
The game starts with a deal. The dealer shuffles a deck of cards, and then deals cards to each player one at a time. Each player may place a bet or simply place the cards face down on the table.
The most important feature of poker is bluffing. If a player is able to bluff the other players, he or she can win the pot.
The most obvious bluff is a forced bet. This is when a player places a bet into the pot even though he or she does not have a valid hand. For example, a player may bet that he or she has the best hand, and then bet another amount to prove this.
The best hand is a combination of a pair of aces and two or more other cards. The lowest possible hand is a pair of aces, followed by a flush, trip sevens, and a straight.
The most interesting poker variants are suited games, and they require the player to use three board cards as opposed to two hole cards. In this case, the player has to make a larger ante.
