Too tight to fold the turn?

[testaaja]

I was planning on raising preflop, but I figured I could limp in too. So these players could make mistakes on the flop/turn. I need some advices on how I ended up playing this hand, I thought on the turn my opponent could easily bluff me so I called down. Opinnions on folding turn? I was atleast getting decent odds here but I don't know if I was right to call down. I really don't know if I love the way I played or if I hate it, thoughts needed [img]/images/graemlins/smile.gif[/img].
