The player to the left of the dealer posts the small blind. In Texas Hold 'Em poker the small blind is half of the minimum table stake. Then the player to the left of the player who has posted the small blind posts the big blind. As per the Texas Hold 'Em poker rules the big blind is the minimum table stake. The intention of posting the blinds is to make sure that the pot is not empty. Since the dealer keeps rotating the players who post the blinds also keep rotating so that the burden of posting the blinds is evenly spread out.
The dealer then deals two cards face down to each player. In poker parlance these cards are called hole cards. According to Texas Hold 'Em poker rules the players can engage in maximum three rounds of betting at the minimum table stakes. If the players think that their two cards offer a reasonable chance to make a winning hand they participate in the betting otherwise they fold. The dealer then opens the flop. The flop is a set of three community cards. In poker parlance community cards are cards all players can use to make their final hands.
The players reassess their chances and engage in another round of betting. In Texas Hold 'Em poker the round of betting after the flop is opened is known as third street. The dealer then opens the fourth community card. This is called the turn. After the turn is opened the betting shifts to the maximum of the table stakes. This round of betting is called fourth street. Finally the fifth and last community card, known as river, is opened by the dealer. Now the players know what their final hand is. A last round of betting takes place and if more than one person is left in the fray then there is a showdown. The highest ranking poker hand participating in the show down wins the pot. The pot consists of all the wagers placed during the course of the deal. In casino poker the casino takes a cut of up to 5% from the pot in order to meet its costs and contribute towards its profit.
