Each poker player is dealt a hole card in the first round while the first card is dealt to the player on the left. The second round of cards that is dealt also consists of hole cards. While the third card each player is dealt is an open card. This open card could also be called the door card.
Normally the player with the biggest open card begins the wager (some prefer to have the player with the smallest card begin the wager). In case if more than one player has the same big card, the person who is nearest to the left side of the dealer will start the wager. At this point every player has three cards, which some people refer to as ‘Third Street’.
This ends when the players have either opted to stay in the game or to quit. The ensuing round is referred to as the ‘Fourth Street’. Here the players who’ve stayed on in the game are dealt another open card and the players place their wager yet again.
The next two rounds, which are referred to as the ‘Fifth Street’ and the ‘Sixth Street’, are open cards. Finally one hole card is dealt to the players that have stayed on in the game. Now every player that has stayed on in the game has three hole cards and four open cards. When the players have placed a wager for the last time they expose their cards and the player with the best game walks away with the kitty.
