The problem people have when playing against aggressive players is that they are not willing to call big bets with a medium hand or bluff raise in big pots. Instead, they just call one street with a weak pair, and if the opponent continues to press with bets on the turn and river, they easily give up.In many situations against aggressive opponents, it is profitable to call on the turn or river with a hand worse than top pair.Sometimes it is a good idea to leave the table if there are too many aggressive players. It will be much easier for you to win against loose-passive opponents who only raise with absolute nuts.
