Hero is sb with A [img]/images/graemlins/club.gif[/img]5 [img]/images/graemlins/club.gif[/img]

preflop:
UTG calls, EP2 calls, 4 folds, CO raises, button folds, hero(SB) calls, BB calls, utg 3-bets, EP2 calls, CO calls, hero calls, BB calls(15 small bets)


I'm pretty sure this was a good call, I knew I had some callers behind me, the reraise was a little unexpected.

flop:
6 [img]/images/graemlins/club.gif[/img]8 [img]/images/graemlins/club.gif[/img]2 [img]/images/graemlins/spade.gif[/img]

Hero(sb) bets, BB calls, UTG raises, CO calls, Hero calls, BB calls (11,5 big bets)

I probably should have raised for value here.
But maybe I was hoping for some turn raises if a club fell or something.

BB is 48/4.8/1 for 21 hands
utg is 7/7/1 for 14 hands
co is 29/14/3 for 49 hands

turn:
T [img]/images/graemlins/club.gif[/img]

hero bets, BB folds, utg calls, co calls

river:
3 [img]/images/graemlins/heart.gif[/img]

hero bets, utg calls, co calls


What is the ideal line to milk these guys?
And was it a good preflop call?
