Poker is a card game where players place an initial wager before being dealt cards. The player who has the best five-card hand wins the pot, which includes all the money that was put down as buy-ins. There may also be side pots in which players share a prize for winning the best 3-card or better hand.
Each player starts by placing an initial bet, which is based on the stakes of the hand and is called the ante. Then, each player is dealt two cards face down (hidden from other players) which they must decide whether to play or fold their hand. If the player decides to play their hand, they must then place a bet equal to the amount of money they placed as an ante, or else call the last raise to remain in the pot.
After the betting round is complete, the dealer puts down three cards that everyone can use, which is called the flop. At this point a second betting phase begins and it is at this time that players can increase their bets.
Generally speaking, the strongest hands are those that can hold up on the flop and in the turn and river. Pocket kings or queens will often win a showdown but an ace on the flop can spell doom for these strong hands. Players must be wary of a board full of flush and straight cards as well.
