Poker is a card game where players compete for an amount of money contributed by the players themselves (called the pot). The outcome of a hand depends on probability, psychology and other factors that the players have chosen to consider.
In most poker games, the first round of betting begins with one or more players placing an initial bet called a blind bet or ante. Once all the players have made a bet, they are dealt cards, usually hole cards. The player with the best hand wins the pot.
Bluffing is a major feature of poker, and it differs from other vying games that use poker hand rankings in that players have the opportunity to make bluffs without having to reveal their cards. In addition, since there is no requirement to show any cards, a bluff can be made at any time during the betting round, resulting in an immediate end to that hand and awarding the pot to the bettor.
Rules of play vary widely from game to game. Some popular variations include Omaha, Draw Poker, and Texas Hold ‘Em.
Pre-flop: The dealer deals two cards face down to each player, and then three community cards (the “flop”) are dealt. The small blind is the first to act; he folds, calls, or raises his bet.
Flop: After the cards are dealt, another round of betting takes place. Each player can discard up to three cards and take new ones from the top of the deck, if desired.
