Looks like 44 or 33 or nothing to me. Gotta pick the rite one!

two pair looks to me to be the most dangerous NL hand.

and cold calling with A3 even to a minraise?

I think this is a call because of the turn. You may fold the flop though. He's overbetting the pot on a non-scary board, which would be retarded with a set. I think a lot this is a semi bluff or 43.
