Poker is a card game where players compete to win the most money. This is achieved by matching the cards in their hand with those in the pot (and in some variants, in other hands).
Before any action can begin, each player is required to place an ante and/or a blind bet. After these initial bets, each player gets a chance to bet, fold or call.
After betting, each player is dealt another card. This is known as the flop.
A flop consists of the first three cards that are dealt to each player. These are usually face-down. The dealer will then place a fifth card on the board which is then visible to all players.
The player with the highest ranking hand wins the pot. This can be a full house, flush, straight or pair.
One of the best ways to develop your instincts is to watch and practice with experienced players. This will give you a feel for how to react in different situations.
