Poker is a card game where players make bets using chips (representing money) and the highest poker hand wins. While luck will always play a part in the game, poker also requires skill and psychology. The best poker players are disciplined, have a sharp focus, and are committed to improving their game over time. They understand that they must learn the proper strategies, manage their bankroll, network with other players and study bet sizes and position. They must be able to mentally handle long sessions and stay focused on the game at hand, which can be taxing on the mind.

In Poker, the cards are dealt in intervals, called betting intervals, according to the rules of the specific game being played. During each betting interval, one player, designated by the rules of the specific game being played, has the privilege or obligation to make the first bet. If he does, then each player in turn must either call the bet by placing into the pot the same number of chips as the last player to act; raise the bet; or decline to put any chips into the pot and drop out of the current betting interval.

In the early stages of a poker tournament it is important to balance aggression with survival. A player who is too aggressive may end up folding before a showdown. On the other hand, a player who is too conservative will miss out on potential profits. Observing your opponents and their betting patterns will help you determine how much aggression to employ.
