[stigmata]

I think I would just call the limp-reraise and call down, just to see what the hell he's up to. I'm sure that's not a profitable line, although you will be shown good overcards or a complete bluff on occasion, making it not quite as expensive as it might seem.

I have been in this situation a few times, and most of the time it is a monster, but a couple of times it was an apparantly sane opponent getting all machismo because I isolated them out of the small blind or something.

The way you played it, he's screaming "monster" at you, and unless he's a complete nutcase you should of folded somewhere....
