Hand vs bel0w

[roo400]

100+9 MTT, still way out of the money.
UTG is Bel0w
I read bel0w as an extreme laggy player capable of bluffing a lot. I haven't been that agressive at this table, people just gave me their chips. With that said, I don't think he raises light UTG with his image/stack. I just never knew what to do in this hand. I'll put the hand in steps.
