Opponents playing styles

Opponents' playing styles: During the hands that you don't enter, observe the playing style of each player and of the group as a whole. Does a certain player only bet when he has good cards or does he bet with anything? Does a player buy-in for a small amount of money and carefully guard it, or does she buy new chips from the dealer frequently? For the table as a whole, are showdowns frequent or rare? How do your opponents react to your play? A big mistake beginning poker players make is playing only their cards and not considering how other people are playing theirs. Your opponents' actions are a source of information that must be used.
