Poker is a card game in which players bet money into a pot (the sum total of all bets in a given deal) in order to win. A player may fold, call (match the amount of a previous bet), or raise (bet more than the amount of a previous bet).
There are many different forms of poker, but the best way to learn is to play with friends. Home games offer a relaxed atmosphere where it is safe to make mistakes without hurting anyone else. Additionally, the game is social and you can make new friends while playing. Many top-level players have graduated alongside their friends from modest home games.
Having a short memory is critical to success in poker. There will be bad beats and coolers, but it is important to remember that you can only control your own decisions at the table. In addition to having a short memory, you also need to learn how to mix up your play and not be predictable. Try to continue-bet your suited ace when it is raised half the time, and just call the other half.
A good strategy is to study the hands of experienced players and try to mimic their actions. The more you practice and watch, the quicker your instincts will become. Moreover, you can also discuss your own hands and playing style with other players for an objective look.
