BB is a fish but not out of line. Got very few hands on him.
BTN is unknown

Flop
I decided to go for a check/call although having the blockers maybe I should bet.
It's 3-way and I didn't wanna get raised, though.

Turn
I could definitely call but I'm not sure I can win the hand if I don't hit
Is it reasonable to raise here?
Does my flop check seem like I never have the nuts even if I raise turn?
