$5-$10 Live- Flopped set on monotone board with maniac

[renodoc]

I don't post here often so please move this if inappropriate.

This is a live Vegas game. The villain is apparently a well-known local player. I played with him the night before this hand and he plays the same. He raises every single pot-- his VPIP is between 97-99%. And he raises the $10 blind to anywhere from $70 to $110 to $200. He also covers the entire table with over $10K in cash.

Knowing this, I tried to exploit it. The one time he failed me I limped with AK and he didn't raise (this was the only hand I can remember where he didn't) and I faced six limpers to a flop, caught an ace, and cursed both of us for not getting more money in pre-flop.

Villain has run some big bluffs, and has been called down several times, losing some pots containing several thousand dollars. He recently moved to my immediate left, which basically meant I would only play hands that I wanted to play for a raise. This disguised my hands well. I believe he thinks I'm "solid" and "don't get out of line." He commented on my play of the night before and was complimentary.

OK- Hero bought in for $3K and now has $5K stack. Villain covers and doesn't care about money. Villain's range is any two cards.

Hero is dealt K [img]/images/graemlins/heart.gif[/img] K [img]/images/graemlins/diamond.gif[/img] in the cutoff.
One limper to hero in the CO and hero limps.
Villain, as expected, makes it $200.
Folded to Hero who calls.

OK, I'll stop there. Comments appreciated. If hero calls the turn, what should the action be on the river if it bricks?
