A card game of chance and skill, poker requires players to make the best hand possible from the cards they have. While luck has a role to play, the game is mostly played by understanding your opponents. This is done by studying the way they play and adjusting your strategy accordingly.

Before the flop, each player has two cards known as hole cards. These are hidden from the other players until the end of the betting round. Then three community cards, referred to as the flop, are revealed. This is followed by another single card referred to as the turn and then a final card referred to as the river. The winning hand is the one that has the best five-card combination from these.

Each player has the option to call (match the amount of money put in by the player before him), raise (bet more than a previous player’s bet) or fold (give up his cards). It is important to know when to make a good call, a bad call and to understand how each decision impacts your overall profitability.
