Getting my feet wet in SH so expect some uber basic questions coming from me in the next while. Anyway, release the hounds!!

I'm pretty sure this one is a call anytime but this weirded me out anyway. No reads.

I know in a full table I would tend to give him credit for AA here. That UTG limp and huge cold call kinda weirded me out.
