Poker is a card game in which players place bets by putting chips into the pot that they believe have positive expected value. There are many different variants of poker, but the objective is to win the pot by having the highest-ranking poker hand at the end of a betting round. Poker can be played by two to 14 people, but in most forms the ideal number of players is 6 or 7.

In poker, you have a much better chance of winning if you play with a more aggressive style than your opponents. A strong player will not tolerate losing to weak players and will be willing to put in larger bets to get more action at the table. A player who is not aggressive will be shoved around by stronger players and will find it difficult to make a profit at the table.

After the initial rounds of betting are complete the dealer deals 3 cards face up on the board that everyone can use, this is called the flop. Another round of betting takes place, this time starting with the player to the left of the dealer.

The most important aspect of poker is understanding how to read your opponents and their tells. This allows you to narrow their range of hands preflop and make more +EV decisions at the tables. It is also important to understand how to read your own tells, this includes your own bluffing behavior and betting patterns.
