There are several different ways to categorize the playing style of a particular player. When considering the ratio of raises to calls a player may be classified as aggressive, moderate or passive. Aggressive means the player frequently bets or raises rather than checking or calling (more than the norm), while passive means the opposite. Another simple set of categories is loose, moderate and tight. A tight player will play fewer hands than the norm, and tend to fold in marginal situations, while a loose player is the opposite. Players may be classified differently for pre-flop and post-flop play.
