Poker is a card game where players bet on the strength of their cards against other players. The object is to execute the best possible actions (raise, call, or fold) based on the current situation and the knowledge of what other players are likely doing, with an eye toward optimizing the long-term expectation for your own bankroll.
Poker can be played in a number of ways: ring games, home games, and tournaments. There are many different rules and strategies for each, but most have the same essential features. In all variants, the standard poker hand is composed of five cards. The rank of a poker hand is determined by its probability and the highest hands win.
A round of betting begins when the dealer deals three cards face up on the table for everyone still in the hand to see. This is known as the flop. Once that betting is complete the dealer puts a fourth card on the table that anyone can use called the turn. The last betting is the river which reveals the fifth community card that players can use to determine the winning hand.
When a player has a good hand such as pocket kings or pocket queens it is usually correct to bet aggressively. This helps to build up the pot and create a large amount of equity against sticky players who will often call your bets with weaker hands. When playing against sticky players it is important to be careful not to get too attached to your hand because the flop could very well spell disaster.
