60-120 hand: Outtricking the Trickster?

[andyfox]

Haven't posted a hand in a while, maybe this one has some interest. 60-120 at Commerce. Two limpers, then a raise from a solid, unimaginative but winning player on the button. I call with A [img]/images/graemlins/club.gif[/img]5 [img]/images/graemlins/club.gif[/img] in the small blind. Big blind calls as do the two limpers. Big blind plays way too loose pre-flop, but is a terrific and tricky post-flop player; he's probably been the biggest winner in the game over the past year.

Flop comes 8 [img]/images/graemlins/club.gif[/img]7 [img]/images/graemlins/club.gif[/img]2 [img]/images/graemlins/spade.gif[/img]. I bet, big blind raises, limpers fold, button 3-bets. I call, as does big blind.

Turn is J [img]/images/graemlins/spade.gif[/img]. I check, big blind checks, button bets. She definitely has a big pair here. I call and now big blind, after hesitating slightly to think, which seems unfeigned to me, raises.

Button thinks, and, while she does, I make up my mind I'm going to raise no matter what she does.

What do you guys think?
