You ' re asking a very general question so it ' s impossible to give a specific answer . There are a number of ways a player can be bad calls too much , doesn ' t call enough , too passive , too nity , bluffs too much , doesn ' t understand relative hand strength , etc . Some opponents may have one bad quality and others may have 6 , these are the leaks in their game and what you use to capitalize on to make profit . If they are bluffing too much , you should generally play tighter and let them do the aggressive betting so they will try to bluff you and when they do , you will have a strong hand . Anytime you are trying to exploit your opponent , you need to have a strong sense of their play style and also how they view your play style because they may adjust their game depending on who their playing against . They may bluff your friend Steve all the time because he ' s a passive nit , but not John because he ' s a giant call station , etc .
