Poker is a card game that involves betting between players, and it can be very competitive. It requires knowledge of probability and game theory, as well as the ability to read opponents and make bluffs. The game is played with a standard deck of 52 cards (although some games use multiple packs, or add extras such as jokers). Cards are ranked from high to low: Ace, King, Queen, Jack, 10, 9, 8, 7, 6, 5, 4 and 3, with the highest ranked hand winning the pot.

In a game of Poker, each player must first put in a forced bet (the amount varies by game but is typically a small sum like a nickel). Then the dealer shuffles the pack and deals cards to each player one at a time beginning with the player on his left. Once the cards are dealt, each player has the option to ‘call’ or ‘fold’. If they choose to call, each player then places their bet into the central pot.

In the second stage of a betting round, the dealer puts down three additional cards face up on the table that anyone can use. This is known as the flop. For the third and final round of betting, the dealer will put down a fifth card that everyone can use, known as the river. For the final time, each player has the chance to check, raise or fold. If they call, they will remain in the pot.
