TO HAVE (Theory)

To have as an ordinary verb means to possess.

Example:  

Shane West has a tattoo of the Celtic symbol for Gemini on his left arm

Have can also be used to mean:

          take (a meal / food or drink / a bath / a lesson, etc),

          give (a party, entertain (guests))

          encounter (difficulties/trouble)

Examples:  

Ninja Turtles have pizza for lunch.

Matt Damon has a party in Hollywood.

Denise Richards and Kate Winslet have troubles with stuff on the Internet that freak   

    them out.

To have as an auxiliary verb is used with the past participle to form tenses.  When

     HAVE is used with the infinitive, it expresses obligation. (I have to go = I must go).

Examples:  

Matt Damon has acted out in Good Will Hunting.

Kate Winslet had been nominated twice for an Oscar by the age of 23.

Christina Rucci should have played in Sleepy Hollow.
