Poker is a game that involves both chance and skill. While the outcome of any given hand definitely involves some element of luck, in the long run the game is won by players who either make bets with positive expected value or who are able to successfully bluff other players for various strategic reasons.
The first step in learning to play poker is getting familiar with the rules of the game. Each player must put in a forced bet called a blind before they see their cards (this is how the game creates a pot to compete for and encourages competition). After the ante has been placed, players are dealt two cards each. Then there are one or more rounds of betting. The highest hand wins the pot.
In poker you want to play hands with the best odds of winning. This means a high pair, three of a kind, straight or flush. You also want to avoid weak hands like two pairs or unmatched cards.
Once betting gets around to you, you can either fold your hand, call or raise. A pair of kings off the deal is pretty good, so you could say to stay if you were satisfied with your hand’s value. However, you don’t know what your opponents have so you would probably raise if you thought you had an outstanding hand or wanted to try and scare them into folding by showing them yours.
