Position, put simply, is where you are sat in relation to the dealer. The dealer is the best position to be sat in because you get to see what all of the other players are doing before you make your mind up. From the dealer the play goes around the table clock wise. The person to the left of the dealer is the small blind and the first to act after the flop. The person to the left of the small blind is the big blind. As these to persons have already placed a bet into the pot and the action is going clockwise, the first person to act once the initial two cards have been dealt is the person to the left of the big blind. Given that there are ten players on the table the blinds and the person to their left are said to be in early positions. The next four persons would be in middle positions and the last three in late positions. Persons in the late positions can play weaker hands that people in the other two positions. The persons in early positions must only play the very best hands because they do not have the privilege of seeing what the other players bet before they do. For example if you are in an early position and you receive a low pocket pair like sixes. You decided to say in the hand and bet. The next player then raises and maybe one or two others call. You will be then in the position of decided to equal there bet or fold. The problem is that you have already placed a bet into the pot and are pot committed. Each of the players in the hand will most likely have two cards that are both higher than yours, an Ace or a higher poker pair. Your only chance of winning will be to hit another six. Also thought the rest of this game you will have to act before the other player, thus they will always have a positional advantage. Being the last person to act, sitting with the dealer button, is a huge advantage not only can you see what everybody else does before you act you also have the opportunity to potentially double the size of the pot. If you raise, assuming everybody else stays in the pot size will double.
