Flopped a set, scary turn.

I considered pushing on the flop and taking it down right there, I just raised instead. The turn brings a probable straight and/or flush. How do you play this one?

Their checks on the turn are weak. I think you have to make some sort of large bet there. If someone raises you and its not too much I'm calling and hoping for a boat/quads. If its a huge raise I'm out. The 6 actually isn't that scary since someone would have to be calling with an inside straight draw on the flop, more than likely someone just paired their sixes, its the flush you should be worried about. That river is about the worst card possible. I'm check/folding after that 8c hits.

I can't make a large bet here b/c I will not know where I stand. This is 25nl and while I have $70 on the table they have less then $25. If I bet the turn, no one is calling, they are either pushing or folding and if they push, then I'm commited to call a bet that I may not want to call.
