Poker is a game of cards, where players compete to form the best hand, or pot, to win at the end of each betting round. The pot is the sum of all bets placed by the players, including those made by the dealer.
A poker hand is determined by a combination of the card ranking and the situation in which you are playing. For example, a pair of kings is usually good off the deal, but is bad when another player holds A-A.
One of the keys to becoming a good poker player is learning to recognize and overcome cognitive biases. The two biggest ones are defiance and hope. Defiance is the tendency to fight for your hand even when it is unlikely to win, and can lead to disastrous results if you have bad cards. Hope is the belief that you will get paid on later streets, even if you don’t have the cards to make it happen.
The other key is knowing when to fold, or check-raise. This requires a strong understanding of the odds in poker, as well as an ability to read other players and watch for tells (not just nervous habits like fiddling with chips or wearing a ring). Using these skills allows you to understand when you are likely to get paid, and when you are not. Over time, a basic understanding of probabilities and EV estimation will become ingrained in your brain, and you’ll develop an intuition for things like frequencies and combos.
