AK postflopp decission

[stokken]

A [img]/images/graemlins/spade.gif[/img]K [img]/images/graemlins/diamond.gif[/img] in mp stack 12K blinds 100/200 no ante yet, folded to me

Lp calls my raise of 4xbb his stack is 10K

This player has been loose, he would call with broadways os or s, with any pocket below 99, above hed reraise, I am pretty sure he would reraise with AK-T, he will also call alot with suited connectors, even high card-x suited. He is also very agressive

BB calls to, not any good read on him yet, but he has called with decent pot odds from blind more often then folded

Flopp A [img]/images/graemlins/club.gif[/img], J [img]/images/graemlins/heart.gif[/img],4 [img]/images/graemlins/heart.gif[/img]

I bet 2/3 of pot, Lp goes all inn, bb folds

Ok Here is how I see it(dont think about why I made these percentages, just be ok with them)
10% pure bluff
12% flush draw, possibly with an A
12% set
Rest two pairs, one pair in braodway, one pair unimproved by flopp, gutshot, 1 pair with the A and weak kicker

Assuming though loose and agressive, but thinking-which hands would u put him on most likely and will u call?
