Poker is played with a standard deck of 52 cards (some variant games add extra jokers). The cards are ranked from high to low: Ace, King, Queen, Jack, 10, 9, 8, 7, 6, 5, 4, 3. Each player gets two personal cards and five community cards. The highest poker hand wins the pot. Depending on the game, you may also draw replacement cards for your community ones.
The first player to act in each betting interval, as designated by the rules of the specific Poker variant you are playing, puts in chips representing money into the pot. Players who follow him must either call or fold their hand. When the final betting interval ends, the players show their cards and the player with the best hand takes the pot.
Aggression is a vital part of the game, but you have to be wise about it. If you play too aggressively, the other players will pick up on it and raise their own bets. This is bad for your win rate. Play your strong value hands and make sensible bluffs, but be careful not to overthink and arrive at the wrong conclusions about other people’s calling range.
When you play in position, you gain more information about the opponents’ holdings and have more control over how much money you put into the pot. You should raise when your opponent is betting aggressively, but be careful not to overdo it. It is also important to learn how to read other players’ tells. These are not only their nervous habits like fiddling with their chips or wearing a ring, but also the way they play their cards and when they make certain calls.
