Poker is a card game in which players place bets into a central pot. The game has many mechanisms by which players may strategically misinform other players about the strength of their hands, as well as bluff. The game of poker combines elements of chance with psychology and mathematical expectation calculations. There is also a high degree of social interaction between players at the table.

The game begins with one or more forced bets, typically an ante and a blind bet. The dealer then shuffles and deals cards to the players, starting with the player to their left. Each player is then required to make a decision: call, fold, or raise.

Raising involves betting a certain amount above the previous player, challenging them to match or raise your bet. This can cause your opponent to fold if you have strong cards, or it can tempt them into calling a weaker hand. This can increase the size of the pot and can lead to a showdown.

The flop, turn, and river reveal additional information about the hand. The flop’s texture (suitedness, connectedness, and/or high/low) can drastically change relative hand strengths. The turn usually sees a few more bets, and the river reveals the final card, which determines whether there is a winner.
