Poker is a game in which players compete to win chips. The game involves using a standard 52-card pack, sometimes with jokers added for variety. While the game is essentially played with a single deck, some casinos use two packs with contrasting colors to speed up the game. One pack is dealt out while the other is shuffled. The previous dealer shuffles the packs and places the dealt cards to the left, passing the shuffled deck to the next dealer.

The betting intervals in each round are regulated by the rules of the game. Each player is required to place a certain number of chips into the pot, or “pot,” as it is commonly known. The player who is the first to place a bet is called the active player. Each player is entitled to raise their bets or fold their hand, but if he does not raise, he loses all of the chips in the pot.

While poker is a game of skill, there is a certain element of luck. Although the chance element plays a smaller role in the average hand, the probability of a player winning the pot depends on the luck of the other players. This is a factor that must be taken into account when analyzing a poker hand.
