There are many different combination of poker hands you get dealt at the poker table, from pocket AA to 72 offsuit. Although, having a strong starting hand like pocket AA’s, pocket KK’s, AK is important, it's not as important as having position.
The first thing to consider before deciding to call, raise, reraise or fold a hand in poker; weather it's a cash game or a tournament, if you have pocket AA's or J9 suited....it's your position at the table. Here is a diagram to show you all the poker positions:
The best position to have in poker is the “Button.” In this position you are 3rd to last to act "Pre-Flop”, last to act after the "Flop", the "Turn" and the "River". Acting last in a poker game is a huge advantage to have. You get last action, so your opponents, in most cases, reveal the strength of their hand by checking, betting, raising or reraising. If they act weak by just calling the blind preflop or checking the flop and the turn, then in most cases they are weak. Being on the button gives options to bluff when it's checked to you, to build the pot when you have a strong hand, to close the action when you are weak or drawing and to fold when opponents show strength. Playing on the button helps you know your opponents and the strength of their hands.
