50NL: am I a hero or is this an easy easy fold?

[jjlydon2]

have been playing around 1 hour at table, villian is loose passive 40/6/1.25...have seen him call preflop with ATC in and out of position. After looking at this hand I realize that I played like a total wimpola, should have raised flop but I'm curious if the turn bet is a clear fold against this opponent...is he flipping over a hand I beat here often enough for me to call/shove?
