On the Button
So you have the dealer button in front of you, what does this mean? The greatest significance is that you are the last person to act (means to bet, raise or fold). This is the most powerful position at the table to be in. You should be playing more hands than you normally would.
Alot of information can be obtained from each player. All you do is sit back and observe. You have a free ride, at least for a while, to decide to play or fold. By raising, you can put a lot of pressure on the other opponents. Forcing them to make a decision if they want to continue playing with what they were dealt.
Your opponents will be playing the same way with the button in front of them. Be on the lookout for the “on the button” player to try to steal your blinds away. They will try to steal the blinds or try to make a raise when everyone limps (calls) in.
