AJs 3 handed

[Alobar]

BB in this hand is a retard. Makes bad bluffs, 3 bets PF on a whim, etc etc. Havent been playing with button much, but he seems aggresive. The table had been playing 5 handed for a while, this is only like the 2nd or 3rd hand its been 3 handed.

Button raises, I 3 bet A [img]/images/graemlins/spade.gif[/img]J[img]/images/graemlins/spade.gif[/img], BB caps, button calls.

Flop comes 7 [img]/images/graemlins/spade.gif[/img]5 [img]/images/graemlins/heart.gif[/img]5 [img]/images/graemlins/spade.gif[/img]

I bet, BB calls, Button raises, we both call.

Turn is a 7

checked to button who bets. I want to raise....bad?
