POKER POSITIONS

Dealer Position

At the table your position is always relative to the dealer for that hand's position. This is one reason why the deal goes around the poker table, so that everyone gets equal betting opportunity in every position.
In community games like Texas Hold`em the most desirable position is the "dealer position"/"button position",because after the flop, the person on the "dealer position" is always going to be the last to act in each round of betting.
You can play more marginal hands on the button because of this advantage.

Early Position in Poker

The 3 players to on left of the dealer are the ones who are in "early position." This is said to be the worst position in poker because you have to act first without knowing beforehand how other players are going to bet or play their hands.
Without any information on how the other players will play their hands, you will have to decide if you are going to fold or raise, it's a good move to play only the best cards in this position.

Middle Position in Poker

The players who comes after the players on the "early position" are the players who are on the "middle position". It is what it sounds like.On this position you will be able to see how the players in the early position play their hands before you act.
In general, you can play a little bit looser in middle position than early position, so you need to be careful.

Late Position in Poker

The "late position" is the best position to have in poker, "Late position" is defined as the dealer
and the players to his right.
When you are in the late position you wil have a lot more time to observe and get information about how the other players play their hand becaus you will see how the majority of the players decide how they play their cards before you have to make your own decision to call,raise or fold.
Sometimes if no one has bet in a round, the players woh are in late position may win the pot simply by raising or placing a bet(this is called "betting position") Most poker players know about betting position and may call bets to bluff when one of the players before him bets.
