Having trouble with a maniac

[Bones920]

I host a home tourney with a $25 buy-in. My Uncle comes over and is always drinking and after about 1 tourney he gets a little drunk and starts raising and going all-in. It seems like when I call him he has something and puts me out, but I know he can't have something every hand. I have read and applied THE PSYCHOLOGY OF POKER but he still gets the best of me. Any ideas on things that might help my game against this maniac? [img]/images/graemlins/confused.gif[/img]
