AK, weired spot 3/6 (6 max)

[WorkNPoker]

Ok sorry I dont have Hand History.

Villain has been pretty loose and Agg. My Image is probably TAG.

Hero $1100
Villan $980

So Iam In BB and UTG raises to 18, Hero re raises to 55 with AK.
He calls.

Flop: A [img]/images/graemlins/spade.gif[/img] 2 [img]/images/graemlins/diamond.gif[/img] 6 [img]/images/graemlins/club.gif[/img]

He checks Hero bets out $80 Villan re raises to $300


Big Re-raise there, any thoughts?

What would you put him on? I thought maybe a set but why such a big raise with a rainbow flop.
