The game consists of initial bank formation by the blinds, four betting rounds and showdown.
Before a game starts the player on the dealer's left posts a small blind, and the player on the small blind's left posts a big blind bet. Big blind is usually twice the size of the small blind bet.
Each player gets two hole cards, cards that the other players cannot see. The player on the big blind's left begins a round of betting. This player can do one of the following:
Call - equal the amount bet in the big blind;
Raise - increase the bet;
Fold - surrender his cards.
The same action can make each player when it is their turn to bet. When all the players make equal bets in the pot, betting round is completed and the game goes to the flop.
One card is dealt face-up on the board in this round. This is known as 'the flop'. Betting on the flop begins with the player on the dealer's left.
When the betting action is completed for the flop round, the 'turn' is dealt face-up on the board. The turn is the fourth community card.
When betting action is completed for the turn round, the 'river' is dealt face-up on the board. The river is final three community cards. The last betting round begins.
When all bets get equal, it is time to show the cards. The last player who bets or raises during the final betting round shows his cards first. If during the last betting round all the remaining players are checking (nobody betting), the first player to the left from dealer shows his cards first. The other players reveal their cards moving clockwise around the table. If player's current hand is weaker than winning hand shown, he may muck his cards. The best five-card hand using any combination of the five community cards and two hole cards wins.
