Poker is a card game in which players place an ante (the amount varies from game to game, but we usually play for a nickel) and then each player gets two cards. Then the betting starts and the highest hand wins the pot.

Once everyone has called the bets on their hands, a third card is dealt face-up in the middle of the table, called the flop. Then there are more bets and players can now choose to fold, call or raise. In the case of raising, you must have a good enough hand to do so.

A strong poker player will not only consider the strength of their own hand, but will also look at the hands that their opponents are holding and will try to work out how likely it is that they have a hand that beats yours. This is called working out an opponent’s range and it is a key part of being able to make profitable decisions at the poker table.

Another important poker fundamental is playing in position. Basically, this means that you will raise more hands than your opponents in late position, and that you will call fewer hands when playing early position. It is a simple principle, but it can dramatically improve your profitability at the poker table.
