Poker is a game of skill, with a small element of chance. Typical hands have an expected value that is based on a statistical distribution, but the player does not control the cards that are dealt to him. Poker is an extremely competitive game, which makes it fun to watch. Nevertheless, the game requires an analysis of the players as well.

The number of players in a poker game can vary, but it is recommended to have six to eight players. The total sum of bets made by all players at the beginning of the hand is known as the pot. The player with the highest ranking poker hand wins the pot if no other player calls. There are literally hundreds of variations of poker.

In some poker variants, there is a set betting interval. The first player is obligated to make the first bet, but the other players can also make a bet. Each player must then place his chips into the pot, equal to the amount contributed by the players before him. This player is called the active player.

After the spread of poker in the 1850s, many variations were added. In some variations, the best hand is the best combination of two distinct pairs, or four of a kind, and in others, the highest pair wins. Another variation is called a straight.
