$10NL Flopped Set Monotone Board

[PinataUT]

I'm working on a bunch of stuff in my game. I've been 'bobbing' last 5k hands w/in $100. Popped in $200 more and started playing more aggro last 1500 hands - bleeding quickly at -6BB and not due to variance. Lots of issues - one is extracting value and another is knowing when to fold.

If it wasn't a push above
Turn: Hero?

What's the best way to extract here? At what point to I become worried if I've called the flop and a scare card comes on the turn (in other words, if there's $5 in the pot and say $50 behind instead of $3 and $3)? If it is a diamond let it go to an oversized bet or check-call and hope it doesn't get too pricey on the river?

Without commenting on this hand's results: my lean right now is to shove (edit: in those $50 behind situations) and I wind up losing people (or trapping myself lol).

Edit: Yeah, I hadn't been calling OOP with PP but didn't want to raise because of stack sizes not being deep enough.
