live 5/10 NL flopped set 1000 BBs deep

[McStinky]

I think I played this hand OK but it was a little complicated so I want to see what people think. The game is 5/10 NL at Foxwoods and the stacks are really deep. Both villain and I have 10,000.

Villain limps in early position. He is a wealthy casual player who plays lots of hands and can stick a lot of money in on draws and bluffs when he shouldn't. Also, I have been beating up on him all day. A mediocre player raises to 30 and I call with 5[img]/images/graemlins/diamond.gif[/img]5[img]/images/graemlins/spade.gif[/img]. My image is tight, solid, occasionally tricky. A decent player with a 2500 stack reraises to 105. Since he is raising so many people, I assume he has a big hand. Villain calls, mediocre guy calls, and I call.

Flop comes 3[img]/images/graemlins/diamond.gif[/img]5[img]/images/graemlins/heart.gif[/img]6[img]/images/graemlins/club.gif[/img]. Villain leads out for 400 fairly quickly. I decide to just call. Should I always raise here? With the preflop reraiser behind me, there is a decent chance he will raise, and then I can reevaluate the situation with a lot more information and more money in the pot. He does indeed raise 500 more. Villain calls the 500, and at this point I put him on some kind of straight draw and figure it is safe to commit. Since I am not sure which cards make him a straight, I figure I need to raise big. I decide to raise the size of the pot, which is 3000 on top. I considered making a smaller raise to make it more likely that he would go crazy and push all in over the top, but ultimately I figured the raise size wouldn't change the probability of this happening enough.

Thoughts?
