Calling FOR MY STACK with middle pair vs a complete maniac, standard?

[Go_Blue88]

Edit-- An attempt to make a catchier title.

Villian is Maniac McManiac. He pushes everything from top pair, to draws, to nothing. I've stacked him once already with a set and I feel like he's tilting here. Standard?

5 handed Hero has 1108, Villian has a lil over 400 I think.

Fold, Hero raises UTG+1 to 20 with A[img]/images/graemlins/spade.gif[/img] 8[img]/images/graemlins/spade.gif[/img], Cstation huge stack calls, VIllian calls in the sb, bb folds.

Flop-- 3[img]/images/graemlins/diamond.gif[/img] 8[img]/images/graemlins/heart.gif[/img] T[img]/images/graemlins/diamond.gif[/img]
