65s wins a big pot

[fisherman112]

playing 5/5 live game, 6 handed
hero has 1000 in chips, villian has 500, pfr has 500
villian loves to slowplay big hands and check raise with them on later streets

utg raises to 15, villian calls in sb, hero calls in bb with 6 [img]/images/graemlins/spade.gif[/img]5 [img]/images/graemlins/spade.gif[/img]

flop is J [img]/images/graemlins/club.gif[/img]8 [img]/images/graemlins/spade.gif[/img]5 [img]/images/graemlins/club.gif[/img]

villian checks, hero check, pfr bets 25, villian calls, hero calls
yes, i know this is loose, but im thinking the turn could bring a 5,6,7 or spade, all of which turn my hand into a viable one. the price was good and i felt i had large implied odds.

turn is 7 [img]/images/graemlins/spade.gif[/img]
my dream card, i have an oesfd

all of a sudden, villian bets pot 100, i debate options here and call, pfr folds

river 9 [img]/images/graemlins/club.gif[/img]
it's the weakest of my outs and im not really happy to see it, but villian checks, at which point confirming my read of a set, i bet 125, villain calls.

thoughts?
