Edit: I grunched.

You know, in NL a limp-reraise usually means AA, but I've found in limit some nutjobs like to do it with suited connectors, once the field has gotten big. I wouldn't be surprised to see two spades here, and I would definitely call down. I would just call the flop raise, though. He did cap preflop and is now raising you. That's not insignificant.
