Generally speaking, poker is a game of chance. Players compete for a pot of money or chips, depending on the variation. The goal is to form the best hand possible. The player with the best hand wins. Some games divide the pot between the best and lowest hands.
Aside from the main game, players also participate in a series of betting rounds. The bets are not directly placed into the pot, but rather collected into a central pot. The pot may be won by making the highest-ranking hand, or by making the best bet.
The ante, or “buy in bet,” is usually $1 or $5. The ante is not required, but it is a good way to contribute to the pot. In some variations, the ace is treated as the lowest card.
The ante is also the shortest round of betting. Players may also be required to contribute to the pot prior to the deal.
The “Hold ’em” or “Hold aces” is a variant of poker. The ace is considered to be the minimum hand, sometimes accompanied by a pair of jacks.
The best hand is the best hand, but only in a 7-card stud. A straight is a hand made of five cards. A flush is a hand made of four cards. A “backdoor flush” is achieved by hitting needed cards on the turn and river.
Aside from the best hand, the smallest card is also considered to be the best. The best hand is usually a straight or flush, but it is possible to make a five-card flush using two wild cards.
