Middle Position

The three or four players in the middle have an easier time of it than those in early position (EP). They get to see what the EPs do before the flop, and won't have to make any decisions after the flop until the blinds and EPs have acted. It's luxury that allows you to play a relatively wider selection of hands. If no one has enter the pot before you, you can think about raising with some of the hands you might have thrown away from early position. And if an EP has already raised, you can safely fold some of your marginal holding.
