5/10 Top 2-Pair vs Strong Player

[BuBu_]

I've been playing for about 3hours and have lost concentration a bit, so am about to come off when..

6handed. Villian raises to $35 UTG. I call in SB with A [img]/images/graemlins/club.gif[/img]K[img]/images/graemlins/heart.gif[/img]. BB calls also.

Villian in hand is a very strong & very aggressive multitabler. Raises quite a few hands PF, including UTG. Stacks are ~1k each.

FLOP ($105) K [img]/images/graemlins/spade.gif[/img]J [img]/images/graemlins/spade.gif[/img]8 [img]/images/graemlins/club.gif[/img]
I lead for $75. BB folds. Villian calls.

TURN ($255) 3 [img]/images/graemlins/heart.gif[/img]
I lead for $190. Villian calls.

RIVER ($635) A [img]/images/graemlins/heart.gif[/img]
$720 left in Villians stack. I have never seen Villian call down as the aggressor before. Hero to act?
