Poker is a card game where players have to make decisions based on their hand equity. A hand is considered to be strong if it contains five cards of the same suit. If the player is dealt a weak hand, he must fold his cards. During the course of play, he must also make decisions based on his outs.

There are various betting options available. Some of them are check, raise, and fold. Players can also make all-in bets, which involve placing all of their chips into the pot. There are also special betting rules for this kind of bet, depending on the type of game. Poker is played using poker chips, which come in red, black, blue, and green colors. Before the game begins, a dealer assigns the chip values to the players. Players exchange cash for poker chips that have a particular value.

The cards used in poker are usually a standard 52-card pack, although some variants use two packs or add jokers. Each card has a specific rank. The lower-ranked cards are high, while the higher-ranked cards are low. The cards are arranged in four suits: ace, king, queen, and jack. The Ace can be low or high, depending on the suit. The cards are shuffled by the dealer before being dealt to the players.

When the flop comes, players use different hands based on position, whether the board is static or dynamic, or whether the opponent is playing bluff. They also use different hands when they’re passive or aggressive. To help them figure out which hands to play based on the situation, players use common shorthand. For example, “JJ+” means to select pocket Jacks and pocket pairs above the Jacks. If an opponent folds, he gets 2:1 and can’t add more hero calls or folds to the hand.
