Poker is a card game in which players place wagers on the outcome of a hand. Unlike some other casino games, such as blackjack or roulette, poker requires skill and strategic thinking to win. There are many different types of poker, but all share a few key elements.

A player must ante up before the betting begins, and can then choose to fold if they don’t think they have a strong starting hand. Alternatively, they can call (match the last player’s bet amount) or raise their own bet to try and win the pot.

Once all players have decided on their action, the flop will be dealt. Then a second round of betting takes place. The final card, known as the River, will be revealed. This will usually make a pair of cards in some hands, or give a flush to others. The highest-ranked hand wins the pot.

It’s important to be able to read your opponents. You can do this in a number of ways, including observing betting patterns. Aggressive actions may indicate that the player is holding a strong hand, while conservative actions could signal they are bluffing. You can also look at their body language, nervous gestures or quick glances at their chip stack for further clues.
