Poker is a card game in which players wager on the outcome of a hand. Although it may seem like a game of pure chance, the best players are those that combine luck with raw technical skill. In order to maximize your edge in poker you need to understand the structure of the game and the rules of the betting. You also need to find optimal frequencies & hands ranges that reflect this structure & rules.
Each betting interval, or round, begins when one player makes a bet. The player to his left must either call the bet, in which case he puts into the pot at least as many chips as the player who made the bet; raise the bet, in which case he places into the pot more than the amount of the bet; or drop out of the pot by not calling the bet (this is called “sandbagging”).
A poker hand contains five cards. A high-ranking hand is more likely to win than a low-ranking one, but players sometimes bluff by raising bets when they do not hold a superior hand.
The first round of betting in a poker game is called the Preflop. Once this betting phase is complete the dealer deals three community cards face-up on the table. These cards are known as the flop. After the flop is dealt the second stage of betting, called the Turn, takes place. After this the final stage of betting, called the River, reveals the fifth and final community card on the table.
