The game of poker involves betting on the outcome of a hand of cards. There is some skill involved, but it depends on the players and how they make decisions under uncertainty. As former professional poker player Annie Duke writes in Thinking in Bets: Making Smarter Decisions When You Don’t Have All the Facts, a key to success is to estimate the probabilities of different scenarios that could occur.
A poker hand is a combination of your own two personal cards and the five community cards that are dealt in a round. The highest poker hand is a royal flush, consisting of the five highest cards in sequence and suit. Other high hands include a straight, a full house, three of a kind, and two pair.
In a poker game, you place an ante before each round. Once everyone has placed their antes, the dealer deals each player five cards. You can then choose to discard one or more of the cards and draw replacements if you wish.
During each betting round, you can choose to call the latest bet or raise it. A raise is a higher amount than the previous bet. If you raise, other players will have to either call your bet or fold their cards.
Some players prefer to play it safe by only calling bets when they have a good hand. However, playing it safe can be costly, as opponents will exploit your predictable style by bluffing more often against you.
