All About Poker:

Poker is a card game that is scored by final card ranking. The goal of playing is to win the pool of money that is wagered. There are a number of categories of poker games that fall under the broad heading of “Poker”; each of these games differs slightly in their rules. Generally a hand (collection of cards) is dealt by the dealer from a standard deck (52 cards) and each player may offer bets based on the original set of cards. In certain variations additional cards may be added to the deck or various cards nominated as “wild cards”, these cards may be given a substitution value by any player who receives one.
After the initial deal each player will take turns making a bet. Each bet is made in a way such that a player will either raise the table bet or accept the current high bet. This betting will continue around the table until all players currently in the game have bet the same amount. The players who do not wish to continue betting are said to “fold” their cards, and can no longer participate in the current hand. The player is then permitted to substitute any or all of the cards in their hand for new cards to be drawn from the deck.

The skill within this game is in knowing which ranking are best achievable from the initial hand and probabilistically exchanging cards that are less likely to result in a winning combination. In the various flavours of poker, this combination can be based on the players on hand or by communal cards (that can’t be traded). In the case that two players have drawn identical combinations (draw), then the winner is decided by determining the holder of highest card. If the highest cards are the same then the next highest card is used, as so on. In the rare case that both card hands are identical the pot is split between players. Poker is very well known in the western world, and enjoys the attention of high profile professional competitions.
As a televised event Poker can be enjoyable not only to observe the strategy of choosing the best combination for a winning hand, but also as a game of human observation. Whilst playing a competitor may “bluff’ or feign a winning hand in order to psychologically warn off opponents from continuing to wager. In the case that a player’s “bluff” is discovered based on a minute twitch or repetitive behaviour they are said to be exhibiting a “tell” that allows their opponents to observe when they are excited about their current hand.
