Poker is a card game played by individuals for an amount of money or chips contributed to a common pot by all players. Players compete to control the amount of money in the pot by predicting what their opponents might do and how they might behave. The game also involves making strategic decisions without knowing the exact probability of a given outcome, which is known as variance.

The rules of poker vary slightly between different games, but the general rule is that each player has two cards, and a five-card community is dealt. A player’s aim is to make the best possible five-card hand by using their own two cards and the five community cards. If a player has the best possible hand and all other players fold, then the player wins the pot (all of the chips that have been bet so far).

In poker, there are a number of strategies for winning, including tight play and aggressive play. Tight play is characterized by playing only strong hands and folding weaker ones. Aggressive play is characterized by raising and calling bets, and can be used to put pressure on other players. Both strategies can be effective, but the more successful strategy is usually a combination of these two approaches.

A tournament is an event run by an organizer at a store, convention, or other venue where people can bring their squad/deck/army/fleet and play against other awesome people who love the same game. The tournament has a specified structure that specifies how many tournament rounds will be played and sets a time limit for the tournament to be completed within.
