Poker is a card game that involves a combination of chance and skill. While poker involves a certain amount of luck, the skill aspect of the game allows players to make decisions that maximize their expected winnings in the long run. This is possible because there are many strategies to employ, and a skilled player can minimize the impact of luck on their overall success.

When a hand is dealt, each player must place a mandatory bet into the pot before they can act. This is called a blind. The player to the left of the dealer has a small blind, and the player two positions to their left has a big blind. The blinds are required so there is an incentive for players to play.

Once all the players have placed their blind bets, there is a round of betting before another card is dealt. The third card is dealt face up and there is a second round of betting before the fourth card is revealed and there is a final round of betting. The best 5 card poker hand wins the pot.

During each round of betting, players can either call or raise. A call means that you match the highest bet made so far in that round. A raise means that you increase the previous high bet. You may also fold your hand if you believe that it has no value.
