Poker is a card game in which players place bets and try to win the pot, or the sum of all bets placed in a hand. The best hands are those consisting of five cards that are of high rank and in sequence and from the same suit. Other hands include three of a kind, a flush, and a pair. The highest card, called the high card, breaks ties.

Each player must first “ante” some amount of money (typically a nickel, but it can vary by game). Once all the players have done so, betting begins. When it is your turn to bet, you must either call the previous player’s bet by putting in a similar amount, raise your own bet to add more money to the pot, or fold. If you fold, you will lose all the chips you have put into that pot.

If you are holding a weak hand, it is often better to fold than to continue betting money at it. However, with good bluffing skills and luck, even the worst hands can win a pot.

When you are new to the game, it is a good idea to observe experienced players for “tells.” These are the little gestures and expressions that give away the strength of their hand. Some common tells are shallow breathing, sighing, nostril flaring, eyes watering, a hand held over the mouth, shaking of the hands, and an increased pulse seen in the neck or temple.
