The better your hand, the better chance you have to stay in the game and beat other players. You will need to understand the various hand rankings to do this. For instance, with an A-Q hand, you have a high probability it will yield a good result. If you have a 4-3 hand, you will be tempted to fold.
Since there is a great deal of hand options in Poker, seasoned professionals in the game advise players to memorise as many hand rankings as possible. While you are learning, you can always use tools to help you.
A great way to illustrate this is to take community cards of 9-8-7 of the same suit while the player’s hole cards are 6 and 5 in a different suit. If an opponent has a 5 and 4 in the same suit, then they get to win the game.
