1. Basic Rules
Every player is dealt two cards face down. These two cards are called your 'hole card'. There is a round of betting before the community cards have been dealt to determine if they would play or not. This stage is known as the pre-flop. Players have three options- check, bet, or fold. After the pre-flop betting is finished, three community cards will be dealth face up in the center of the table. This stage is called the Flop.
Once the three cards have been shown, another round of betting will begin. Once this is over, a fourth community card will be dealt in the center of the table. This stage is called the Turn. After another round of betting is finished, the fifth and final community card is placed on the table. This is called the River.
There is one last round of betting after the River card is shown. Players must bet according to the best hand they have in their hand in combination with the community cards. Players may only use up to 5 cards to make a hand. Players cannot have two combinations of hands (such as a Straight and Flush) to bet with. Only the highest value combination will be used to determine the winner. The best five-card hand wins.
However, many people often try to outbet the other players to scare them out, or get them to fold before the "showdown", or the point where everyone reveals their final hands. If one folds before the showdown, their hand will not be shown to the table. If all but one player folds before the showdown, the winning player's hand will not be shown to the table either. Only when there are two or more players at a showdown will the cards be shown and the winner will be determined by the best hand.
