In Texas hold 'em, as in all variants of poker, individuals compete for an amount of money or chips contributed by the players themselves. Because the cards are dealt randomly and outside the control of the players, each player attempts to control the amount of money in the pot based either on the hand they are holding, or on their prediction as to what their opponents may be holding. The game is divided into a series of hands or deals; at the conclusion of each hand, the pot is typically awarded to one player. A hand may end at the showdown, in which case the remaining players compare their hands and the highest hand is awarded the pot; that highest hand is usually held by only one player, but can be held by more in the case of a tie. The other possibility for the conclusion of a hand occurs when all but one player has folded and have thereby abandoned any claim to the pot, in which case the pot is awarded to the player who has not folded. The objective of winning players is not to win every individual hand, but rather to make mathematically and psychologically correct decisions regarding when and how much to bet, raise, call or fold. By making such decisions, winning poker players can maximize their expected gain on each round of betting, thereby increasing their long-term winnings.
