Poker is a card game where players bet chips (representing money) in a central pot. A player with the best hand wins the pot. The cards are dealt in a series of betting intervals, called rounds. In each round, one player is designated as having the privilege or obligation to make the first bet. Each player then must call that bet by putting into the pot the number of chips equal to or greater than the amount contributed by the previous player.

In the early stages of the game, players are usually checking and folding their cards unless they have strong hands. During this time, it is important to analyze the other players and determine their tendencies. The more you play and watch, the quicker your instincts will become.

During the next stage, the flop is revealed. In this stage, a player with a good pocket pair can win by betting against players holding lower-ranked hands and bluffing. A player with a weak hand can also win by raising on the flop and forcing the other players to fold.

It is important to understand how to read the other players at the table, and to differentiate between aggressive and conservative players. Conservative players rarely raise and tend to fold early in the hand, making them easy to bluff against. Aggressive players, on the other hand, are risk-takers and often bet high during the early stages of a hand before they have seen how their opponents react to their own cards.
