I think a big limp-reraise is fine if effective stacks are 200xBB. Sure, it gives away your hand to most people, but you are really just looking for one clueless guy to either not believe you have a big hand or to be sure you have a big hand and want to "crack" you with a small pair or suited connector. There is usually that one clueless guy at every 5/10 NL table.

The guy's raise to 500 on the flop actually scares me a little. If I had played with someone a ton and had an extremely good sense of the bet amount they use, I could actually fold there (VERY rarely). But given what you know, I say shove the flop. It seems like the chances of him committing his chips won't change that much from the flop to the turn, so might as well get the money in earlier.
