Poker is a card game with a complex ruleset that can be played by two or more people. It is a game of chance and skill, with the latter requiring understanding of probability and statistics. A good understanding of game theory is also necessary, as well as the ability to make informed bluffs.

There are many variations on the game, but all share certain core elements. In a basic game, each player is dealt five cards and bets on whether or not they have the best hand. The more unique the combination of cards, the higher the hand rank. Players may also choose to fold, in which case they forfeit the amount bet by the other players, or call (match) a bet. The game is won by the player who makes the highest-ranking hand or, more commonly, by making a bet that no one else calls.

Some poker variants require a bet called a blind, which happens before the deal and is made by a player designated by the game’s rules. Players can raise this bet or check.

The goal is to maximise winning hands while minimising losses. This strategy is called MinMax, and it applies to many aspects of life. For example, if you are confident in a job interview, you might get through ahead of someone with a better CV. However, you could lose if you’re caught bluffing, so it’s important to weight your chances.
