What are some of the points of conflict between Huck and his father?

Pap used to beat him..... mostly when he was sober because he couldn't catch him when he was drunk.

He used to always whale me when he was sober and could get his hands on me; though I used to take to the woods most of the time when he was around.

Pap wants Huck to give him his money.

"Looky here—mind how you talk to me; I'm a-standing about all I can stand now—so don't gimme no sass.  I've been in town two days, and I hain't heard nothing but about you bein' rich.  I heard about it away down the river, too.  That's why I come.  You git me that money to-morrow—I want it."
