Bluff against a super-lag

[Mackerel]

FullTilt Poker NL100 (6-max)

Villain is a super-lag 68/57/7 in ~200 hands. He's raising every other hand to 5+ BB and aggressively betting/raising almost every pot he's in. Nonetheless, I don't think he's stupid, and I've seen him take his foot of the gas and fold a few times. I've butted heads with him a couple of times, and it's about even: once he sucked out on my pocket pair after calling the whole way, and once he found a fold on the river after betting all the way when I pushed and he was crushed [img]/images/graemlins/frown.gif[/img]. Other than that, we are pretty much staying out of each others way (he's directly across the table, and has been folding quite a bit when I raise, and vice versa). But he's pretty much running over the table raising so much, and it's really starting to annoy me, when this hand comes up.

I have ~$100 (just rebought after another donk hit his two out set) and villain has me covered 3x.
