$100nl; top set 3way; give me a better line

[netstorm]

I checked flop becuase I have the deck crippled, and there are basically no scare cards for me. I wanted to let them catch up. Im not sure about my turn play. Do I lead out? As played, how do I proceed? Call, then shove river? Raise right now?
